"Atomic calculations for tests of fundamental physics"Marianna Safronova , University of Delaware [Host: Kent Paschke]
ABSTRACT:
I will give an overview of applications of atomic calculations for atomic physics tests of fundamental physics, including the study of parity violation, search for EDM, and search for variation of fundamental constants. The goals of high-precision atomic parity violation (APV) studies are to search for new physics beyond the standard model of the electroweak interaction by accurate determination of the weak charge and to probe parity violation in the nucleus. I will discuss the current status and future prospects of atomic parity violation studies and the implications for searches for physics beyond the standard model. The recent advances in theoretical methodology that allowed to reduce theoretical uncertainty in the analysis of the cesium experiment are briefly outlined. I will also discuss recent accurate calculation of the nuclear spin-dependent parity-violating amplitude. New result still leads to the discrepancy between constraints on weak nucleon-nucleon coupling obtained from the cesium anapole moment and those obtained from other nuclear PV measurements.
