Dalitz analyses with B → Dh(h) decays at LHCb

We present studies performed by the LHCb experiment with beauty to open charmed meson decays B→Dh(h(′))B→Dh(h(′)), h(′)=π,Kh(′)=π,K. Using the 1 fb−11 fb−1 results of B±→(hh(′))Dh±B±→(hh(′))Dh±, 1 fb−11 fb−1 results of B±→(K∓π±π+π−)Dh±B±→(K∓π±π+π−)Dh± and 1 fb−1+2 fb−11 fb−1+2 fb−1 results of model-independent Dalitz plot analysis of B±→(KShh)DK±B±→(KShh)DK± modes, γ is constrained to be (67±12)°(67±12)°. Further LHCb measurements with multi-body B or D decays are presented in the proceeding. The results include the model-dependent measurements of B±→(KShh)DK±B±→(KShh)DK± and the CP violation measurements of B±→(KSKπ)Dh±B±→(KSKπ)Dh± and B→(hh(′))DK⁎0B→(hh(′))DK⁎0.
