 | \small Resolution on the \phit angle as a function of the \epem invariant mass as obtained from \lhcb simulated events. |
 | \small Invariant mass distribution for (a) the \BdKstGamToee and (b) the \BdKstee decay modes and the three trigger categories grouped together. The dashed line is the signal PDF, the light grey area corresponds to the combinatorial background and the dark grey area is the PR background. The solid line is the total PDF. The two vertical dotted lines on the \BdKstee plot indicate the signal window that is used in the angular fit. |
