Virtual contributions from D⁎(2007)0 and D⁎(2010)± in the B → Dπh decays
We study the quasi-two-body decays B→D⁎h→Dπh with h=(π,K) in the perturbative QCD approach and focus on the virtual contributions from the off-shell D⁎(2007)0 and D⁎(2010)± in the four measured decays B¯0→D0π+π−, B¯0→D0π+K−, B−→D+π−π− and B−→D+π−K−. For the B¯0→D⁎+π−→D0π+π− and B¯0→D⁎+K−→D0π+K− deca...
