LHCb - Measuring the CKM Angle γ Using B0 → DK+π− Decays at LHCb

A measurement of the CKM angle $\gamma$ using $B^0 \to D K^+ \pi^-$, $D \to (K_S^0 h^+ h^-, h^+ h^-, h^+ h^- h^+ h^-)$ decays with $h=K, \pi$ is presented. A simultaneous binned fit is performed on all decays in both the B and D-decay phase space to optimise sensitivity to $\gamma$. Binned populati...

description A measurement of the CKM angle $\gamma$ using $B^0 \to D K^+ \pi^-$, $D \to (K_S^0 h^+ h^-, h^+ h^-, h^+ h^- h^+ h^-)$ decays with $h=K, \pi$ is presented. A simultaneous binned fit is performed on all decays in both the B and D-decay phase space to optimise sensitivity to $\gamma$. Binned population distribution and strong-phase parameters are measured for the first time in the B-decay phase space. Current progress is described alongside preliminary background-inclusive pseudo-experiment study results to estimate the expected statistical sensitivity to $\gamma$.
