It is shown, using a track-level simulation, that the use of the $D_s^- \to K^{*0}K^-$ decay channel for $D_s^-$ reconstruction, in additioon with the previously studied $D_s^- \to \phi \pi^-$ mode, enables two fold gain in the ATLAS…

$B^\pm \to (D^0, \bar D^0, D_{CP})K^{*\pm}_{0,2}$ decays are helpful in determining the CP violation angle $\gamma$, and we analyze these decay processes within the perturbative QCD approach based on $k_T$ factorization. We found that the…
