Description
Title: Transverse spin asymmetry as a probe of new physics beyond the SM
Speaker: Bin Yan
Abstract:
The absence of signals for new heavy resonances at the LHC suggests that the scale of new physics (NP) likely significantly exceeds the electroweak scale. The Standard Model Effective Field Theory (SMEFT) has become a valuable framework for systematically capturing potential NP effects, with leading contributions expected from dim-6 operators. However, chirality-flipping dim-6 operators for light fermions, which are poorly constrained as their interference with the SM will be highly suppressed. In this talk, I will discuss recent progress in exploring these NP effects through transverse polarization effects without such suppression, and it also offering a new avenue to investigate potential CP violation effects.
