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. As Bourjaily put it: Why are you summing up millions of things when the answer is just one function?, We knew at the time that we had an important result, Parke said.

The answer for each scattering amplitude takes the form of a volume of a high dimensional polytope defined by the positivity of grassmanians, hence the name amplituhedron. There are diagrams with one loop, two loops, three loops and so on increasingly baroque iterations of the scattering process that contribute progressively less to its total amplitude. VWx%3f|NV7?%zHEbW5Y)e4OuT0g. Article 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. 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.

Schwarz and J. Scherk, Supersymmetric Yang-Mills Theories, Nucl. It is therefore very premature to say that this makes conventional quantum field theory obsolete. For those who keep asking about interesting, promising ideas about fundamental physics to work on, twistors are something they definitely should look into.

S.N. 3 0 obj Next page. stream On certain two-dimensional boundaries, where the Amplituhedron geometry reduces to a polygon, we check that both spaces map to the same dual polygon. The amplituhedron A 6, 2 (2) is the image of the top-cell for the positive Grassmannian G + (2, 6), labelled by the decorated permutation {3,4,5,6,7,8}. Thinking about both this talk and the Tegmark story, an odd parallel occurred to me. In planar N = 4 supersymmetric YangMills theory, also equivalent to the perturbative topological B model string theory in twistor space, an amplituhedron is defined as a mathematical space known as the positive Grassmannian. Edward Witten described the work as "very unexpected" and said that "it is difficult to guess what will happen or what the lessons will turn out to be".[5]. Is it always clear that when one simplifies these integrands, we do not lose the information when one simplify these terms out? But its not from the object changing. P. Benincasa and M. Parisi, Positive geometries and differential forms with non-logarithmic singularities. It enables simplified calculation of particle interactions in some quantum field theories. We propose that for the cases with minimal number of points the canonical form of these geometries corresponds to the product of parity conjugate amplitudes at tree as well as loop level. 259 (2021) 107653, [arXiv:2002.07146].

F. Gliozzi, J. Scherk and D.I. This is exciting because people have always speculated that some of these things may be emergent in theories of quantum gravity. In 1986, scientists used supercomputers and Feynman diagrams to calculate the likelihoods of various outcomes of six gluon interactions. 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.

The Amplituhedron Nima Arkani-Hamed, Jaroslav Trnka Perturbative scattering amplitudes in gauge theories have remarkable simplicity and hidden infinite dimensional symmetries that are completely obscured in the conventional formulation of field theory using Feynman diagrams. [9][7], The geometric nature of the theory suggests in turn that the nature of the universe, in both classical relativistic spacetime and quantum mechanics, may be described with geometry. He sketched line drawings of all the ways a scattering process could occur and then summed the likelihoods of the different drawings. Nima Arkani-Hamed Article Now integrands are not trivial things but an amplitude is much more difficult. This work is a baby step in that direction.. The amplituhedron, or a similar geometric object, could help by removing two deeply rooted principles of physics: locality and unitarity. I've seen a talk where Arkani-Hamed claimed to have made some progress since then but it's not published yet. % Bourjaily, S. Franco, D. Galloni and C.

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.

[10], Since the planar limit of the N=4 supersymmetric YangMills theory is a toy theory that does not describe the real world, the relevance of this technique for more realistic quantum field theories is still unknown, but it provides promising directions for research into theories about the real world. The amplituhedron can be given a self-contained denition in a few lines as done below in section 9. This undermines the case for even a transient, unobservable existence for such virtual particles. S. Franco, D. Galloni, B. Penante and C. Wen, Non-Planar On-Shell Diagrams, JHEP 06 (2015) 199 [arXiv:1502.02034] [INSPIRE]. If space works as it seems to be working, then every particle in existence has an information 'tail' that extends outwards by as much as 99.9% of the particle's true size. [3] The scattering amplitude can thus be thought of as the volume of a certain polytope, the positive Grassmannian, in momentum twistor space. I. Prlina, M. Spradlin, J. Stankowicz, S.

Cite this article. Interactions that were previously calculated with mathematical formulas thousands of terms long can now be described by computing the volume of the corresponding jewel-like amplituhedron, which yields an equivalent one-term expression. There are further constraints imposed by requirements of locality and unitarity and all these constraints together are sufficient to construct the scattering amplitudes in the planar limit without doing the sum over Feynman diagrams. But what to do with it?, The message of Parke and Taylors single-term result took decades to interpret. The news that physicists have discovered a geometrical object that simplifies a lot our models of quantum physics has recently became viral. You will find that more technical answers here get more upvotes and this at least avoided equations. Article Now it is just considered to be another toy model, albeit a very sophisticated one with gravity, gauge fields and matter in 4 dimensions.

Because we know that ultimately, we need to find a theory that doesnt have unitarity and locality, Bourjaily said, its a starting point to ultimately describing a quantum theory of gravity..
