Relativistic corrections to double Bc meson production in e+e- annihilation
Abstract
Within the framework of nonrelativistic QCD (NRQCD) factorization, we investigate the relativistic corrections to the production of double Bc mesons in e+e- annihilation. The study covers center-of-mass energies from the production threshold up to 2mZ, considering both the photon and Z0-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.
