New Physics Probes: Atomic Parity Violation, Polarized Electron Scattering and Neutrino-Nucleus Coherent Scattering

Understand

Atomic Parity Violation (APV) is usually quantified in terms of the weak nuclear charge $Q_W$ of a nucleus, which depends on the coupling strength between the atomic electrons and quarks.

• In this work, we review the importance of APV to probing new physics using effective field theory.
• Furthermore, using $SU(2)$ invariance, we correlate our findings with those from neutrino-nucleus coherent scattering.
• Moreover, we investigate signs of parity violation in polarized electron scattering and show how precise measurements on the Weinberg angle, $\sin \theta_W$, will give rise to competitive bounds on light mediators over a wide range of masses and interactions strength.
