Abstract
Within the framework of nonrelativistic QCD (NRQCD) factorization, we investigate the relativistic corrections to the production of double 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 factors of approximately 0.6. The azimuthal asymmetry, angular distribution, and transverse momentum distribution are also presented.
