Standard Model Precision Electroweak Measurements at HL-LHC and Future Hadron Colliders

Abstract

We investigate the uncertainties for current and future measurements of electroweak (EW) parameters at hadron colliders. These include the measurement of the mass of the top quark ($M_T$), the direct measurement of the mass of the W boson ($M_W^{direct}$), the measurement of the effective EW mixing angle ${\sin }^2{\theta }_{\mathrm{eff}}^{\mathrm{lept}}$(M${}_Z$), and the measurement of the on-shell EW mixing angle ${\sin }^2{\theta }_W=1-M_W^2/M_Z^2$ which is equivalent to an indirect measurement of the W mass ($M_W^{indirect}$). Reduction of a factor of 2 to 3 in the measurement errors is expected in the future.
