Blaze: A High performance Big Data Computing System for High Energy Physics

open access: yesJournal of Physics: Conference Series, 2023
High energy physics (HEP) is moving towards extremely high statistical experiments and super-large-scale simulation of theory. In order to handle the challenge of rapid growth of data volumes, distributed computing and storage frameworks in Big Data area

String theory: an update [PDF]

open access: yes, 2002
An overview of some of the developments in string theory over the past two years is given, focusing on four topics: realistic (standard model like) models from string theory, geometric engineering and theories with fluxes, the gauge theory-gravity ...

The Gravitational Two-Loop Counterterm is Asymptotically Safe [PDF]

open access: yes, 2016
Weinberg's asymptotic safety scenario provides an elegant mechanism to construct a quantum theory of gravity within the framework of quantum field theory based on a non-Gau{\ss}ian fixed point of the renormalization group flow.

RG flow and thermodynamics of causal horizons in higher-derivative AdS gravity

open access: yesJournal of High Energy Physics, 2016
In arXiv:1508.01343 [hep-th], one of the authors proposed that in AdS/CFT the gravity dual of the boundary c-theorem is the second law of thermodynamics satisfied by causal horizons in AdS and this was verified for Einstein gravity in the bulk.

Quantum machine learning in high energy physics [PDF]

open access: yesMachine Learning: Science and Technology, 2020
Machine learning has been used in high energy physics (HEP) for a long time, primarily at the analysis level with supervised classification. Quantum computing was postulated in the early 1980s as way to perform computations that would not be tractable ...

Flat-space Quantum Gravity in AdS/CFT [PDF]

open access: yes, 2015
Motivated by the task of understanding microscopic dynamics of an evolving black hole, we present a scheme describing gauge-fixed continuous time evolution of quantum gravitational processes in asymptotically flat spacetime using the algebra of CFT ...

Explainability of High Energy Physics events classification using SHAP

open access: yesJournal of Physics: Conference Series, 2023
Complex machine learning models have been fundamental for achieving accurate results regarding events classification in High Energy Physics (HEP). However, these complex models or black-box systems lack transparency and interpretability. In this work, we

Trans-Planckian Issues for Inflationary Cosmology [PDF]

open access: yes, 2012
The accelerated expansion of space during the period of cosmological inflation leads to trans-Planckian issues which need to be addressed. Most importantly, the physical wavelength of fluctuations which are studied at the present time by means of ...

NGN, QCD_2 and chiral phase transition from string theory [PDF]

open access: yes, 2006
We construct a D2-D8-$\bar{D8}$ configuration in string theory, it can be described at low energy by two dimensional field theory. In the weak coupling region, the low energy theory is a nonlocal generalization of Gross-Neveu(GN) model which dynamically ...
