[ sin2θWeff = 0.23142±0.00073(stat)±0.00052(sys)±0.00056(theory) ] The LHCb collaboration has submitted a paper based on run 1 data which reports the measurement of a fundamental parameter of the Standard Model (SM), the electroweak mixing angle, θW. This parameter quantifies the relative strengths of electromagnetism and the weak force. It is, therefore, an important experimental challenge to…
