In this episode, we are thrilled to host the renowned physicist, Dr. Kotwal, to explore the implications of the new and precise measurement of the W boson mass. The W boson, a mediator of the weak force between elementary particles, has its mass heavily constrained by the symmetries of the Standard Model (SM) of particle physics. Therefore, measuring the mass of the W boson poses a stringent test of the SM.

Dr. Kotwal discusses the Collider Detector at Fermilab (CDF) Collaboration's recent findings, which unexpectedly revealed that the mass of the W boson was significantly higher than the SM predicts. This discrepancy, measured at an impressive 7 standard deviations, is drawn from data collected in proton-antiproton collisions at the Tevatron particle accelerator.

Delving into the implications of this finding, Dr. Kotwal helps listene ...
