The weak angle gamma from one-particle inclusive CP asymmetries in the B(s) system

Abstract

We compute CP asymmetries of one-particle inclusive B(s) --> D(s) X decay rates. We find that the weak angle gamma could in principle be extracted from these asymmetries although they are very small. Taking the decay width difference into account, we find that the time integrated CP asymmetries are of the order A=1.4 10^(-4) sin(gamma). Some large uncertainties remain due to the lack of experimental data.
