E. Herrmann and J. Parra-Martinez, Logarithmic forms and differential equations for Feynman integrals, JHEP 02 (2020) 099 [arXiv:1909.04777] [INSPIRE]. 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. 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. The amplituhedron looks like an intricate, multifaceted jewel in higher dimensions. Rev. Y. J. 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".

A. Hodges, Eliminating spurious poles from gauge-theoretic amplitudes, JHEP 05 (2013) 135 [arXiv:0905.1473] [INSPIRE]. Article In this paper, we show how the Kleiss-Kuijf relations arise from the geometry of the momentum amplituhedron. This is a modest advance in mathematical physics, one that for some reason a few months ago garnered a lot of hype (see here for more about this). The new paper will still only be about ${\cal N} = 4$, right? Finally, in 2005, a new research team derived the guesswork equation for that same six-gluon interaction, and this time they had a solid guess about what their method (the BCFW method, named after the researchers' last names) could mean. Now integrands are not trivial things but an amplitude is much more difficult. Rev. We will motivate its denition from elementary considerations, and show how scattering amplitudes are extracted from it. The terms in these BCFW relations were coming from a different world, and we wanted to understand what that world was, Arkani-Hamed said. When subatomic particles interact, different outcomes are possible. I dont know how long the talk actually went on.

There is no way in this geometry to decouple the piece which is space-time from the piece which is quantum mechanics. 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. J.S., The conclusion, then, is that adding those up gives you the volume of a mysterious polyhedron albeit a mind-bogglingly difficult one from a computational standpoint. L. Ferro and T. Lukowski, Amplituhedra, and Beyond, arXiv:2007.04342 [INSPIRE]. I've seen a talk where Arkani-Hamed claimed to have made some progress since then but it's not published yet. It enables simplified calculation of particle interactions in some quantum field theories. (N is the number of particles involved in a scattering process.). Encoded in its volume are the most basic features of reality that can be calculated, "scattering amplitudes," which represent the likelihood that a certain set of particles will turn into certain other particles upon colliding.

About an hour and a half into the talk, people were reminded that he doesnt mind if they leave while hes speaking. It was a geometric representation of real particle data, such as the likelihood that two colliding gluons will turn into four gluons. It is possible that true emergence may be a feature in a wider generalisation of the theory especially if it can be applied to quantum gravity where emergence is expected to be a feature.

To say that the multiverse mania is fashionable you have to provide evidence: what fraction of the vacua contain string theorists? A particle is only as local as its leading and trailing edges (in terms of 2-D visualization of information propagation in a low-pass filtered system/space) are in terms of how such a particle is interacting with the 'edges' of another particle (which is why electron size differs depending on which other particle is used to measure it.).

Open Access . As seems to often be the case, the Arkani-Hamed talk was a bit bizarre as an event. Triangles in sacred geometry are thought to symbolize balance and harmony. 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. We have to learn new ways of talking about it. Phys. 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. This is a modest advance in mathematical . Z. Bern, J. J. M. Carrasco and H. Johansson, New Relations for Gauge-Theory Amplitudes, Phys. The parameters of the problem change: it becomes a purely mathematical problem. ", True, except for the time part. What is being calculated are scattering amplitudes in a conformally invariant theory, with the simplest example the planar limit of tree-level amplitudes of N=4 super Yang-Mills. It should offer a completely new way to calculate the probability amplitudes in quantum field theories relatively to the usual Feynman diagrams but the observable results are finally the same. 2023 Springer Nature Switzerland AG. 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. The latest tool for calculating how particles interact (figure 2) was introduced in a December 2013 paper, "The Amplituhedron," by Nima Arkani-Hamed, Professor in the School of Natural Sciences, and his student Jaroslav Trnka.The amplituhedron gives a concrete example of a theory where the description of physics using spacetime and quantum mechanics is emergent, rather than fundamental. is there a chinese version of ex. qLUw&:6Y#n+1Ao2&7 @-CNA for some basic info, links, and the big picture.

0 In 1986, scientists used supercomputers and Feynman diagrams to calculate the likelihoods of various outcomes of six gluon interactions. The publication of the paper by Arkani-Hamed and Trnka is imminent. The above output gives us the number of boundaries of each dimension in the amplituhedron. [3][4], The connection between the amplituhedron and scattering amplitudes is a conjecture that has passed many non-trivial checks, including an understanding of how locality and unitarity arise as consequences of positivity. The amplituhedron is not built out of space-time and probabilities; these properties merely arise as consequences of the jewels geometry. Article We have indications that both ideas have got to go, Arkani-Hamed said. In a conventional perturbative approach to quantum field theory, such interactions may require the calculation of thousands of Feynman diagrams, most describing off-shell "virtual" particles which have no directly observable existence. Lower-dimensional amplituhedra, which correspond to interactions between finite numbers of particles, live on the faces of this master structure. 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. [1][2], Amplituhedron theory challenges the notion that spacetime locality and unitarity are necessary components of a model of particle interactions. The usual way to calculate scattering amplitudes in quantum field theory is by adding together the effects of many Feynman diagrams, but the number and complexity of diagrams increases rapidly as the number of loops increases and if the coupling is strong the sum converges slowly making it difficult to do accurate calculations. However I do think that many more advances will be required to work up from super yang mills to sugra and then string theory.

Yesterday Nima Arkani-Hamed was here at Columbia, giving a theory seminar on the topic of the Amplituhedron, which is a characterization of the integration region in a calculation of scattering amplitudes by integrating over regions in the so-called positive Grassmannian. Of course I was aware of some of the twistor part of the amplitudes story (see for instance here), but I was unaware of the important role played by Andrew Hodges, of Penroses twistor group at Oxford, in these recent developments.
