Iulia M. Comsa, Moritz Firsching, Thomas Fischbacher
2019 Journal of High Energy Physics  
Using de Wit-Nicolai D=4 N=8 SO(8) supergravity as an example, we show how modern Machine Learning software libraries such as Google's TensorFlow can be employed to greatly simplify the analysis of high-dimensional  ...  We provide detailed information on the location, symmetries, and particle spectra and charges of 192 critical points on the scalar manifold of SO(8) supergravity, including one newly discovered N=1 vacuum  ...  unusual Machine Learning adventure.  ...

Prescriptive Unitarity for Non-Planar Six-Particle Amplitudes at Two Loops [article]

Jacob L. Bourjaily, Enrico Herrmann, Cameron Langer, Andrew J. McLeod,, Jaroslav Trnka
2019 arXiv   pre-print
Importantly, we use the same basis of integrands for both theories, so that the presence or absence of residues at infinite loop momentum becomes a feature detectable by inspecting the cuts of the theory  ...  This work has been updated to take into account the results of [arXiv:1911.09106], which leads to a simpler and more uniform representation of these amplitudes.  ...  Acknowledgements This work was performed in part at the Aspen Center for Physics, which is sup-  ...

L-Violating Supersymmetry - Implementation in PYTHIA and study of LHC discovery potential [article]

P. Z. Skands
2001 arXiv   pre-print
The subsequent analysis uses a combination of primitive cuts and neural networks to optimize the discriminating power between signal and background events.  ...  In the Minimal Supersymmetric Standard Model (MSSM), the simultaneous appearance of lepton and baryon number violation causes the proton to decay much faster than the experimental bound allows.  ...  In many ways, the master thesis is likely to be the only chance a student gets to learn about and discuss within so few pages so many aspects of his/her field, here from quantum gravity effects on global  ...

Physics in the CERN Theory Division [chapter]

1996 History of CERN  
The two most important supergravity models, the first N = 1 supergravity and the largest N = 8 one, were discovered at the Ecole Normale Superieure in Paris, where also many of their properties have been  ...  The N = 8 supergravity was the end of a road, the road to Symmetry.

Theoretical Summary Lecture for EPS HEP99 [article]

Michael E. Peskin
2000 arXiv   pre-print
In this article, I review a number of topics that were highlighted at the meeting and have more general importance in high energy physics.  ...  This is the proceedings article for the concluding lecture of the 1999 High Energy Physics Conference of the European Physical Society.  ...  In the process, we have learned that physics at this microscopic scale has a basis as rational as chemistry. Quarks and leptons move, not by magic, but because there is a mechanism at work.  ...

Expanding the parameter space of natural supersymmetry

Amin Aboubrahim, Wan-Zhe Feng, Pran Nath
2020 Journal of High Energy Physics  
The U(1) X and the hypercharge U(1) Y of the MSSM have kinetic and Stueckelberg mass mixing where the mixings are ultraweak.  ...  Models of this type are testable in dark matter direct and indirect detection experiments and at the high luminosity and high energy LHC.  ...  The scan is carried out with xBIT [62] which uses pytorch for artificial neural networks (ANN) on which the machine learning scan algorithm [63] is based and xSLHA [64] for reading SLHA files.  ...

Beyond the Standard Model [chapter]

Eliezer Rabinovici
2020 Particle Physics Reference Library  
Magic The universe as viewed with string probes is full of magic ambiguities and symmetries unheard of before.  ...  Over this decade we have learned or should have learned the importance of patience, humility, and diversity of ideas. Not the type of lessons that theoretical physicists appreciate too much.  ...

Correlations vs connectivity in R-charge

Joan Simón
2018 Journal of High Energy Physics  
The holographic relation between quantum correlations and connectivity of spacetime is explored for single R-charged AdS_5 black holes and their half-BPS limits (superstars).  ...  In a two boundary set-up, the wormhole between both universes reduces to a designable and computable quantum mechanical correlation between the dual microscopic degrees of freedom in the BPS limit.  ...  R 4 AdS = 4πgsN 4 s and G10 = 8π 6 g 2 2 8 s (see for example [62] ).  ...

General Relativity, Mental Causation, and Energy Conservation [article]

J. Brian Pitts
2019 arXiv   pre-print
The conservation of energy and momentum have been viewed as undermining Cartesian mental causation since the 1690s.  ...  Modern discussions of the topic tend to use mid-19th century physics, neglecting both locality and Noether's theorem and its converse.  ...  Acknowledgments This work is supported by the John Templeton Foundation, grant #60745. It does not necessarily reflect the views of the Foundation.  ...

Scale invariance vs conformal invariance [article]

Yu Nakayama
2014 arXiv   pre-print
We give a complementary holographic argument based on the energy-condition of the gravitational system and the space-time diffeomorphism in order to support the claim of the symmetry enhancement.  ...  We believe that the possible enhancement of conformal invariance from scale invariance reveals the sublime nature of the renormalization group and space-time with holography.  ...  Chen for the host, and all the participants for kind invitation and stimulating discussions. I also thank all the people I talked with for stimulating discussions on the subject.  ...

Aspects of M-theory and quantum information

Leron Borsten, Michael Duff
The dawn of the 21st-century has also played witness to the birth of the information age and with it the world of quantum information science.  ...  In 2006 the entropy formula for a particular 8-charge black hole appearing in M-theory was found to be given by the 'hyperdeterminant', a quantity introduced by the mathematician Cayley in 1845.  ...  The magic supergravities F A = F(J A 3 ) again have U-dualities given by the magic square [40] .  ...
