Eighth Meeting on


May 12-16, 2019

Indiana University, Bloomington

The Eighth Meeting on CPT and Lorentz Symmetry will be held in the Physics Department, Indiana University in Bloomington, Indiana, U.S.A. on May 12-16, 2019. The meeting will focus on tests of these fundamental symmetries and on related theoretical issues, including scenarios for possible violations.

Topics include:

  • experimental and observational searches for CPT and Lorentz violation involving
    • accelerators and colliders
    • astrophysical birefringence, dispersion, and anisotropy
    • atomic and molecular spectroscopy
    • cavities, oscillators, resonators
    • Cherenkov radiation
    • clock-comparison measurements
    • CMB polarimetry
    • cosmic rays
    • decays of atoms, nuclei, and particles
    • equivalence-principle tests with matter and antimatter
    • exotic atoms, muonium, positronium
    • gauge bosons, the Higgs boson
    • gravimetry
    • gravitational waves
    • high-energy astrophysical observations
    • hydrogen and antihydrogen spectroscopy
    • lasers, masers
    • matter-wave interferometry
    • meson and baryon properties
    • neutral-meson interferometry
    • neutrino mixing and propagation, neutrino-antineutrino oscillations
    • particle-antiparticle comparisons
    • photon and particle scattering
    • post-Newton gravity in the solar system and beyond
    • second- and third-generation particles
    • short-range gravity
    • sidereal and annual time variations, compass asymmetries

    • time-of-flight measurements
    • torsion and nonmetricity
    • trapped particles, ions, and atoms

  • theoretical and phenomenological studies of CPT and Lorentz violation involving
    • physical effects at the level of the Standard Model, General Relativity, and beyond
    • origins and mechanisms for violations
    • classical and quantum field theory, gravitation, particle physics, and strings
    • mathematical foundations, Finsler geometry
