Measurement of the Effective Weak Mixing Angle in $p\bar{p}\to Z/{\gamma }^{\ast }\to {\ell }^{+}{\ell }^{-}$ Events

D0 Collaboration

We present a measurement of the effective weak mixing angle parameter ${\sin }^2{\theta }_{\text{eff}}^{\ell }$, in $p\bar{p}\to Z/{\gamma }^{\ast }\to {\mu }^{+}{\mu }^{-}$ events at a center of mass ener…
