(DNP) T1-6 Precision Physics and Tests of Fundamental Symmetries | Physique de précision et tests des symétries fondamentales (DPN)
- Jeffery Martin (The University of Winnipeg)
This talk reviews selected topics of the Fundamental Symmetries sector of Nuclear Physics from the theoretical point of view. It focuses on three themes of interest to the Canadian experimental community: electric dipole moments, neutral currents, and beta decays. Lepton flavor violation, where major new international experiments are about to come online, will also be discussed.
Experimental tests of fundamental symmetries using nuclei and other particles subject to the strong nuclear force have led to the discovery of parity (P) violation and the discovery of charge-parity (CP) violation. It is believed that additional sources of CP-violation may be needed to explain the apparent scarcity of antimatter in the observable universe. A particularly sensitive and...
The MOLLER experiment at Jefferson Lab aims for an ultra-precise determination of the weak mixing angle $\sin^2\theta_W$ by measuring the parity-violating asymmetry $A_{\rm PV}$ in polarized electron-electron (Moller) scattering. For the approved 88 calendar week run, the proposed accuracy on $A_{\rm PV}$ is 0.7 parts per billion corresponding to an overall relative measurement accuracy of...
The MOLLER (Measurement Of a Lepton Lepton Electroweak Reaction) experiment, in preparation at Jefferson Lab, aims to constrain physics beyond the Standard Model using parity-violating Moller scattering at 11 GeV. The parity-violating asymmetry between the cross-sections for right- and left-handed helicity beam electrons scattered from the atomic electrons in a liquid hydrogen target is...
