Possible Manifestation of a Non-Pointness of the Electron in $e^+e^-$ Annihilation Reaction at Centre of Mass Energies 55-207 GeV
/ Chen, Yutao (Hefei, CUST) ; Lin, Chih-Hsun (Taiwan, Inst. Phys.) ; Liu, Minghui (Hefei, CUST) ; Sakharov, Alexander S. (Manhattan Coll., Riverdale ; CERN) ; Ulbricht, Jürgen (Zurich, ETH) ; Zhao, Jiawei (Hefei, CUST)
The experimental data from VENUS, TOPAS, OPAL, DELPHI, ALEPH and L3 collaborations, collected from 1989 to 2003, are applied to study the QED framework through direct contact interaction terms approach, using the annihilation reaction $\rm e^+ e^-\rightarrow \gamma\gamma(\gamma)$. The analysis involves performing of a $\chi^{2}$ test to detect the presence of an excited electron $e^{*}$ and evidence of non-point like behavior in the $e^+e^-$ annihilation zone. [...]

Higgs Induced Triboluminescence in Binary Black Hole Mergers
/ Chitishvili, Mariam (Javakhishvili State U.) ; Gogberashvili, Merab (Javakhishvili State U. ; Tbilisi, Inst. Phys.) ; Konoplich, Rostislav (Manhattan Coll., Riverdale) ; Sakharov, Alexander S. (Manhattan Coll., Riverdale ; CERN)
We conjecture that the Higgs potential can be significantly modified when it is in close proximity to the horizon of an astrophysical black hole, leading to the destabilization of the electroweak vacuum. In this situation, the black hole should be encompassed by a shell consisting of a "bowling substance" of the nucleating new phase bubbles. [...]

Robust Constraint on Lorentz Violation Using Fermi-LAT Gamma-Ray Burst Data
/ Ellis, John (King's Coll. London ; CERN) ; Konoplich, Rostislav (New York U. (main) ; Manhattan Coll., Riverdale) ; Mavromatos, Nikolaos E. (King's Coll. London ; U. Valencia (main)) ; Nguyen, Linh (Manhattan Coll., Riverdale) ; Sakharov, Alexander S. (New York U. (main) ; Manhattan Coll., Riverdale ; CERN) ; Sarkisyan-Grinbaum, Edward K. (CERN ; Texas U., Arlington (main))
Models of quantum gravity suggest that the vacuum should be regarded as a medium with quantum structure that may have non-trivial effects on photon propagation, including the violation of Lorentz invariance. Fermi Large Area Telescope (LAT) observations of gamma-ray bursts (GRBs) are sensitive probes of Lorentz invariance, via studies of energy-dependent timing shifts in their rapidly-varying photon emissions.
