Title: B decays into a scalar/tensor meson: In pursuit of determining the CKM angle {gamma}

Abstract

In this work, I suggest a new way for determining the CKM angle {gamma} via B decays into a scalar/tensor meson without any hadronic uncertainty. The proposed idea makes profits of the two triangles formed by the B{sup {+-}}{yields}(D{sup 0},D{sup 0},D{sub CP}{sup 0})K*{sub 0(2)}{sup {+-}} (1430) decay amplitudes. The advantages in it are large CP asymmetries and the avoidance of the use of doubly Cabibbo-suppressed D decays. Branching ratios of B{sup {+-}}{yields}(D{sup 0},D{sup 0},D{sub CP}{sup 0})K*{sub 0(2)}{sup {+-}} (1430) are estimated to have the order 10{sup -6}- 10{sup -5} and therefore measurable on the ongoing LHCb experiment and future experimental facilities. The usefulness of other related channels, for instance the neutral B{sub d} decays into DK*{sub 0(2)} (1430) and B{sub s}{yields}(D{sup 0},D{sup 0})M(M f{sub 0}(980),f{sub 0}(1370),f Prime {sub 2}(1525),f{sub 1}(1285),f{sub 1}(1420),h{sub 1}(1180)), the B{yields}D{sup {+-}}a{sub 0,2}{sup {+-}} for the extraction of {gamma}+ 2{beta} and the B{sub s}{yields}D{sup {+-}}K*{sub 0,2}{sup {+-}} to access {gamma}+ 2{beta}{sub s}, is also discussed in brevity.
