Relativistic corrections to double B c meson production in e + e – annihilation*
Abstract
Abstract Within the framework of nonrelativistic quantum chronodynamics factorization, we investigate relativistic corrections to the production of a pair of family mesons in annihilation. The study covers center-of-mass energies from the production threshold up to , considering both the photon and -boson propagated processes. We find that the relativistic corrections are significant, with the corresponding K factors of approximately 0.6. The azimuthal asymmetry, angular distribution, and transverse momentum distribution are also presented.
