A Case Study of COVID Mass Gain Phenomenon: W Bosons

• Pouya Asadi (Massachusetts Institute of Technology)

Electroweak precision tests allow us to look for new models beyond the Standard Model. I will review how electroweak precision fits are carried out and how the new CDF II measurement of W mass affects the fit. I will also discuss the contribution of some simplified extensions of Standard Model to oblique parameters S and T that can explain the observed anomaly.
