The Hawking paradox and the Bekenstein resolution in higher-dimensional spacetimes / Hod, Shahar
The black-hole information puzzle, first discussed by Hawking four decades ago, has attracted much attention over the years from both physicists and mathematicians. [...]

Quasi-local holographic dualities in non-perturbative 3d quantum gravity I – Convergence of multiple approaches and examples of Ponzano–Regge statistical duals / Dittrich, Bianca ; Goeller, Christophe ; Livine, Etera R. ; Riello, Aldo
This is the first of a series of papers dedicated to the study of the partition function of three-dimensional quantum gravity on the twisted solid torus with the aim to deepen our understanding of holographic dualities from a non-perturbative quantum gravity perspective. [...]

WKB approximation for a deformed Schrodinger-like equation and its applications to quasinormal modes of black holes and quantum cosmology / Lu, Fenghua ; Lv, Bochen ; Wang, Peng ; Yang, Haitang
In this paper, we use the WKB approximation method to approximately solve a deformed Schrodinger-like differential equation: [−ħ2∂ξ2g2(−iħα∂ξ)−p2(ξ)]ψ(ξ)=0 , which are frequently dealt with in various effective models of quantum gravity, where the parameter α characterizes effects of quantum gravity.

Indirect search for light charged Higgs bosons through the dominant semileptonic decays of top quark t  →  b (→ B / D  +  X )+ H + (→ τ + ν τ ) / Abbaspour, S. ; Moosavi Nejad, S. Mohammad ; Balali, M.
In this work we introduce a new channel to indirect search for the light charged Higgs bosons, which are predicted in several extensions of the standard model (SM) such as the two-Higgs-doublet models (2HDMs). [...]

Muon-to-electron conversion in mirror fermion model with electroweak scale non-sterile right-handed neutrinos / Hung, P.Q. ; Le, Trinh ; Tran, Van Que ; Yuan, Tzu-Chiang
The muon-to-electron conversion in aluminum, titanium and gold nuclei is studied in the context of a class of mirror fermion model with non-sterile right-handed neutrinos having masses at the electroweak scale. [...]

A framework for finding anomalous objects at the LHC / Chakraborty, Amit ; Iyer, Abhishek M. ; Roy, Tuhin S.
Search for new physics events at the LHC mostly rely on the assumption that the events are characterized in terms of standard-reconstructed objects such as isolated photons, leptons, and jets initiated by QCD-partons. [...]
