New Constraint for Isotropic Lorentz Violation from LHC Data
David Amram, Killian Bouzoud, Nicolas Chanon +3
New calculations for the kinematics of photon decay to fermions in vacuo under an isotropic violation of Lorentz invariance (LV), parameterized by the Standard-Model Extension (SME…
Nonminimal planar electrodynamics modified by higher-derivative terms
Letícia Lisboa-Santos, João A. A. S. Reis, Marco Schreck +1
We consider a (2+1)-dimensional modified electrodynamics endowed with terms that are either Lorentz-invariant or Lorentz-violating and involve an ever increasing number of derivati…
The boundary of the gravitational Standard-Model Extension
Carlos M. Reyes, Marco Schreck
A modification of General Relativity that is based on the gravitational Standard-Model Extension and incorporates nondynamical background fields has recently been studied via the A…
New Developments in the Hamiltonian Formulation of the Gravitational Standard-Model Extension
M. Schreck
This chapter of the proceedings for the Ninth Meeting on CPT and Lorentz Symmetry is dedicated to the Hamiltonian formulation of the minimal gravitational Standard-Model Extension.…
Hubble tension as a guide for refining the early Universe: Cosmologies with explicit local Lorentz and diffeomorphism violation
Mohsen Khodadi, Marco Schreck
This paper is dedicated to assessing modified cosmological settings based on the gravitational Standard-Model Extension (SME). Our analysis rests upon the Hubble tension (HT), whic…
