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…
Impact of Lorentz violation on anomalous magnetic moments of charged leptons
Andreas Crivellin, Fiona Kirk, Marco Schreck
We address the question whether a violation of Lorentz symmetry can explain the tension between the measurement and the Standard-Model prediction of the anomalous magnetic moment o…
