At one time (about 1980) N=8 SUGRA was considered a candidate theory of everything until it was noticed that its gauge group is too small and it does not have chiral fermions or room for symmetry breaking. T. Lukowski, On the Boundaries of the m = 2 Amplituhedron, arXiv:1908.00386 [INSPIRE]. This constrains the form that the scattering amplitudes can take since they must be a representation of these symmetries. Lett. The usual picture of space and time, and particles moving around in them, is a construct. The mathematical tools needed are twistors and grassmanians. And unitarity holds that the probabilities of all possible outcomes of a quantum mechanical interaction must add up to one. Phys. B 122 (1977) 253 [INSPIRE]. P.

Interactions that were previously What's the difference between a power rail and a signal line? They will have to find a way to go beyond the planar limit, generalise to higher dimensions, include gravity and identify the relevant symmetries for string theory. The amplituhedron, or a similar geometric object, could help by removing two deeply rooted principles of physics: locality and unitarity. P. Benincasa and M. Parisi, Positive geometries and differential forms with non-logarithmic singularities. Note: This article was updated on December 10, 2013, to include a link to the first in a series of papers on the amplituhedron. For quantum mechanics and gravity to coexist, locality has to go, and the amplituhedron suggests that this is possible.

For what my opinion is worth I do think that this new way of looking at quantum field theories will turn out to something that generalises to something that is really part of nature. A. Hodges, Eliminating spurious poles from gauge-theoretic amplitudes, JHEP 05 (2013) 135 [arXiv:0905.1473] [INSPIRE]. We cant rely on the usual familiar quantum mechanical space-time pictures of describing physics, Arkani-Hamed said. More complicated diagrams have loops, where colliding particles turn into unobservable virtual particles that interact with each other before branching out as real final products. 2021, 111 (2021). Tegmark early in his career downplayed the multiverse part of his interests, in order to make sure people took him seriously as a scientist. Math. Res. These numbers are what particle physicists calculate and test to high precision at particle accelerators like the Large Hadron Collider in Switzerland. xWn6@c$HhCEYI,'=,9-I93C]t?GQ twchn.

Trnka, Unwinding the Amplituhedron in Binary, JHEP 01 (2018) 016 [arXiv:1704.05069] [INSPIRE]. The on-shell scattering process "tree" may be described by a positive Grassmannian, a structure in algebraic geometry analogous to a convex polytope, that generalizes the idea of a simplex in projective space. The real excitement is in the idea that it extends in some way to theories which could be physical. Also as usual though, its unclear why he thinks its a good idea to not bother trying to fit his talk into a conventional length, but just keep talking. L. Ferro, T. ukowski and R. Moerman, From momentum amplituhedron boundaries toamplitude singularities and back, JHEP 07 (2020) 201 [arXiv:2003.13704] [INSPIRE]. as in example? The details of a particular scattering process dictate the dimensionality and facets of the corresponding amplituhedron. Due to the group-theoretic structure underlying color decompositions, color-ordered amplitudes enjoy various identities which relate different orderings. Phys.

[1] Arkani-Hamed suggests this is why amplituhedron theory simplifies scattering-amplitude calculations: in the Feynman-diagrams approach, locality is manifest, whereas in the amplituhedron approach, it is implicit. P. Tourkine, Integrands and loop momentum in string and field theory, Phys. I have advocated the idea that string theory has very large symmetries in the form of necklace algebras so these ideas seem on the right track to me. Just as the inside of a triangle is a region in a two-dimensional space bounded by intersecting lines, the simplest case of the positive Grassmannian is a region in an N-dimensional space bounded by intersecting planes. The resulting observable quantities are the same as calculated by other methods so you don't have to throw away the usual textbooks on quantum mechanics and quantum field theory; they haven't been invalidated. B 425 (1994) 217 [hep-ph/9403226] [INSPIRE]. SKU:PC7258611. These days, its somewhat the reverse, with Arkani-Hamed using, if not the multiverse, quantum gravity research at the boundaries of science, in order to get people to take seriously his work on what they otherwise might decide was just an obscure corner of mathematical physics. N. Arkani-Hamed, J.L. String theory, a framework that treats particles as invisibly small, vibrating strings, is one candidate for a theory of quantum gravity that seems to hold up in black hole situations, but its relationship to reality is unproven or at least confusing. It represents a novelty not only in physics but also in mathematics, generalizing the concept of a convex polygon. J.L. S.N. Commun. The amplituhedron can be given a self-contained de nition in a few lines as done below in section 9. The degree of efficiency is mind-boggling, said Jacob Bourjaily, a theoretical physicist at Harvard University and one of the researchers who developed the new idea. I. Prlina, M. Spradlin, J.

The amplituhedron is not a physical object, but an abstraction that allows scientists to model how the details of particle interactions play out. 259 (2021) 107653, [arXiv:2002.07146]. Williams and Y.X. Yes, a lot of what is fashionable is not worthwhile.

(N is the number of particles involved in a scattering process.). The simplest Feynman diagrams look like trees: The particles involved in a collision come together like roots, and the particles that result shoot out like branches. No matter what your views on that, I think if one goes back and looks at the topics fashionable at any given moment in HEP theory, most of the time youll find that some of the fashionable topics didnt turn out to be worthwhile, while people doing some very unfashionable things in obscurity turned out to be doing something much more worthwhile. Recently, a strange duality has been found between string theory and quantum field theory, indicating that the former (which includes gravity) is mathematically equivalent to the latter (which does not) when the two theories describe the same event as if it is taking place in different numbers of dimensions. There was a lot about quantum gravity of an extremely vague sort. volume2021, Articlenumber:111 (2021) <> Penrose developed twistors also with a quantum gravity motivation: they provide a very different set of basic variables, with usual space-time points not the fundamental objects.

But at the time, gluons and their interactions were so complex that understanding them seemed impossible especially since calculating gluon interaction outcomes involved hundreds of Richard Feynman diagrams and pages of algebra. A seemingly simple event, such as two subatomic particles called gluons colliding to produce four less energetic gluons (which happens billions of times a second during collisions at the Large Hadron Collider), involves 220 diagrams, which collectively contribute thousands of terms to the calculation of the scattering amplitude. eFY1ZZI&:FYS^w-j0qz+ 5`;d57Mm*va1nw;#w=-NN]]9R06JuDLi@L$eNm{.U Rev. Its volume represents, in theory, the total amplitude of all physical processes. Having space-time and unitarity as a derived concept may be a step towards emergence but it is not the same thing. In other words, locality might be an emergent feature of space-time. Introduction.-The amplituhedron in planar N 4 SYM [1] [2] [3] is arguably one of the most surprising mathematical structures of scattering amplitudes we have seen, where basic principles like. E. Herrmann, C. Langer, J. Trnka and M. Zheng, Positive Geometries for One-Loop Chiral Octagons, arXiv:2007.12191 [INSPIRE]. Math. The physicists hoped that the amplitude of a scattering process would emerge purely and inevitably from geometry, but locality and unitarity were dictating which pieces of the positive Grassmannian to add together to get it. Why is superdeterminism generally regarded as a joke? Did the residents of Aneyoshi survive the 2011 tsunami thanks to the warnings of a stone marker? J. L.

Lam and H. Thomas, Binary Geometries, Generalized Particles and Strings, and Cluster Algebras, arXiv:1912.11764 [INSPIRE]. Article Article The news that physicists have discovered a geometrical object that simplifies a lot our models of quantum physics has recently became viral. The revelation that particle interactions, the most basic events in nature, may be consequences of geometry significantly advances a decades-long effort to reformulate quantum field theory, the body of laws describing elementary particles and their interactions.

The pieces of the positive Grassmannian that were being calculated with twistor diagrams and then added together by hand were building blocks that fit together inside this jewel, just as triangles fit together to form a polygon. One wants to extend these methods to loops, to higher order terms in 1/(number of colors), and to non-conformally invariant theories like ordinary Yang-Mills (at the tree level, ordinary and N=4 super YM give the same results). Rev. It is therefore very premature to say that this makes conventional quantum field theory obsolete. The basic idea was that the central objects of the theory were rays of light, twistors, rather than particles, and the various terms of the method could be interpreted as volumes of tetrahedrons in twistor space. In mathematics and theoretical physics (especially twistor string theory), an amplituhedron is a geometric structure introduced in 2013 by Nima Arkani-Hamed and Jaroslav Trnka.

Twistor theory involves some wonderfully different ways of thinking about four-dimensional geometry, and these seem far more likely to play some role in future advances in the direction of unification than any of the tired ones (GUTs, SUSY, string theory) that have dominated the field for so long. Using Feynman diagrams, the same calculation would take roughly 500 pages of algebra.

There is some hope that the ideas can be broadened beyond the planar limit but that may be a long way off. Artists rendering of the amplituhedron, a newly discovered mathematical object resembling a multifaceted jewel in higher dimensions. At least at tree level the scattering amplitude for tree level is the same as the scattering amplitude for non-supersymmetric theories or QCD for gluon scattering. Instead of describing scattering processes in terms of familiar variables like position and time and depicting them in thousands of Feynman diagrams, the BCFW relations are best couched in terms of strange variables called twistors, and particle interactions can be captured in a handful of associated twistor diagrams. j;lmQ,! They are local and unitary in space-time, but they are not necessarily very convenient or well-adapted to the shape of this jewel itself, Skinner said. Probably only $N=4$ but during the SUSY 2013 talk, Nima indicated he has an idea what it means to describe non-scale-invariant theories - a whole new region that can produce singularities away from the main "jewel". They then made an educated guess and posited a one-line formula to replace the more than 200 Feynman diagrams and countless lines of algebra and their single equation was correct. In other words, the traditional machinery of quantum field theory, involving hundreds of Feynman diagrams worth thousands of mathematical terms, was obfuscating something much simpler. How can I explain to my manager that a project he wishes to undertake cannot be performed by the team?
