Fifth IUCSS Summer School and Workshop on the

Lorentz- and CPT-violating Standard-Model Extension

May 10-19, 2024

Indiana University, Bloomington

The Fifth IUCSS Summer School and Workshop on the Standard-Model Extension (SME) will be held as an online event hosted by the Physics Department, Indiana University in Bloomington, from Friday May 10 to Sunday May 19, 2024. This School is aimed primarily at students and researchers in theory and experiment who seek a pedagogical introduction to the SME framework.

The School will cover the fundamentals of the field, including the effective field theory framework for Lorentz and CPT violation. This framework will serve as the stepping stone for more advanced explorations of current trends in phenomenological, experimental, and theoretical research areas, progressing to the forefront of the study of Lorentz and CPT symmetry. This lecture material will be reinforced and supplemented by discussion sessions. The School will also provide the participants a showcase for their own work in short presentations. An IUCSS Workshop on recent research in SME physics will be held concurrently during the last part of the School.

Topics scheduled for coverage include:

  • Theory
    • relationships among local and global spacetime transformations
    • origins of spacetime-symmetry violations
    • spontaneous violations, NG and massive modes
    • explicit breaking, no-go constraints
    • role of effective field theory
    • minimal and nonminimal SME in Minkowski spacetime
    • quantum corrections, renormalization
    • gravitational SME
    • Riemann-Finsler and Lorentz-Finsler geometries
  • Phenomenology
    • sidereal variations, spherical decomposition
    • level shifts in atomic and nuclear systems
    • observables in particle traps
    • effects on neutrino oscillations, propagation, and decay
    • flavor-changing signals in leptons and hadrons
    • predictions for particle colliders and storage rings
    • gravitational phenomenology
    • astrophysical signatures
    • applications in condensed-matter physics
  • Experiment
    • resources for identifying existing constraints
    • matter-antimatter comparisons
    • spectroscopic studies of atoms and nuclei
    • tests with neutrinos
    • QCD effects in DIS, Drell-Yan processes, meson oscillations, top decays
    • bounds from flavor-changing effects
    • laboratory and solar-system tests of gravity
    • searches using astrophysical observations

There is no registration fee for the School or Workshop, but online registration on or before Friday May 3, 2024 is required. The total attendance is likely to be capped, so early registration is advised to avoid disappointment.
