Towards the measurement of the CKM angle γ using the Tree-level decay B --> D[hh]K*[Ksπ] at the LHCb experiment

Abstract : This document presents, a preliminary study towards the measurement of the CKM angle through the tree level decay B --> D[hh]KὨ[Ksπ] where hh = K+K−, π+π− or Kπ. Using the LHCb data collected in 2011 2012 and the Monte Carlo simulation sample, a selection on discriminating variables has been preformed in order to purify the decay chain from the background events. Following the selection cuts, the reconstructed invariant mass distributions of the particles Ks,Kπ,D,B were presented. The subsisting events were split based on D’s final state and B’s charge. Afterwards, they were used for the GLW and ADS methods where the CP violation observables AADS, RADS, ACP+, RCP+ were measured experimentally.
