Second IUCSS Workshop on

Theoretical Aspects of the Standard-Model Extension

November 6-7, 2020

Indiana University, Bloomington

The Second IUCSS Workshop on Theoretical Aspects of the Standard-Model Extension will be held as an online event hosted by the Physics Department, Indiana University in Bloomington, Indiana, U.S.A. on November 6-7, 2020.

The Workshop focus will primarily be on theoretical and phenomenological aspects of violations of spacetime symmetries in the context of the comprehensive effective field theory based on General Relativity and the Standard Model, the Standard-Model Extension (SME). The format will consist of short live-streamed talks summarizing recent developments and prospects for future advances.

Topics in the SME to be discussed at the Workshop are expected to include:

  • realistic effective field theory with gravity, gauge, and matter fields
  • origins and mechanisms for violations of spacetime symmetries
  • spontaneous and explicit Lorentz and diffeomorphism breaking
  • causality, stability, unitarity, CPT, spin-statistics
  • mathematical foundations, Riemann-Finsler and Lorentz-Finsler geometry
  • nonminimal gravitational, gauge, and matter sectors, Chern-Simons terms
  • Nambu-Goldstone, massive, gauge, and auxiliary modes, constrained quantization
  • radiative corrections, renormalization, Casimir effect
  • field redefinitions, coordinate and frame choices
  • post-Newton gravity, gravitational waves, black holes, equivalence principle
  • phenomenology of abelian and nonabelian field theories
  • birefringence, dispersion, and anisotropy in the gravity, gauge, and matter sectors
  • spin dependence in matter-gravity and matter-gauge couplings
  • condensed-matter applications, Weyl semimetals
  • experimental and observational searches for violations

There is no registration fee for this Workshop, but online registration before Tuesday November 3 is required. The total attendance is likely to be capped, so early registration is advised to avoid disappointment.
