Preface

The Seventh Meeting on CPT and Lorentz Symmetry, CPT16, was held from Monday June 20 to Friday June 24, 2016 in the Physics Department at Indiana University, Bloomington. The event was the latest in a series of conferences held every three years since inception in 1998 and focused on investigations of spacetime symmetries and their violations. This volume contains brief reports on the presentations at the meeting.

Many contributions concern experimental and observational issues related to the search for CPT and Lorentz violation. Topics covered include accelerator and collider experiments, astrophysical studies, decays and propagation of particles, equivalence-principle tests with matter and antimatter, matter interferometry, neutrino and antineutrino mixing and propagation, oscillations and decays of neutral mesons, searches with resonant cavities and laser interferometers, spectroscopy of atoms and various exotic species including antihydrogen, and tests of gravity in the laboratory and beyond. The theoretical works treat the phenomenology of CPT and Lorentz violation, its possible origins and mechanisms, and mathematical topics such as Finsler geometry. The reports are ordered following first the program of talks and then the posters.

The meeting owes its success to numerous people who worked intensely behind the scenes. Ralf Lehnert handled many of the crucial organizational aspects. Daily operations were assured by Kathy Hirons, Yunhua Ding, Josh Foster, gnes Roberts, Neil Russell, Arnaldo Vargas, Alexandre Vieira, Zhi Xiao, and Rui Xu. Assistance with digital imaging and animations was provided by Kevin Kosteleck. I would also like to express my appreciation to Glenda Bitner, Susan Brown, Anne Foley, and Dave Sprinkle for their help with meeting logistics and to Yubing Zhai and Linda Kwan for their efficient work on the current proceedings and earlier volumes in this series. Funding for the meeting was provided in part by the Indiana University Center for Spacetime Symmetries (IUCSS) and by the Indiana University Office of the Vice Provost for Research.

We study sub-part per billion systematic effects in a Bragg-diffraction atom interferometer relevant to a precision-measurement of the fine-structure constant. The multi-port nature of Bragg diffraction gives rise to parasitic interferometers, which we suppress using a magic Bragg pulse duration. The sensitivity of the apparatus is improved by the addition of AC Stark shift compensation, which permits direct experimental study of sub-ppb systematics. This upgrade allows for a 310
