Abstract
The cross section of the γγ → B c(B c ∗) bc process is calculated. It is shown that near threshold the pseudoscalar state production is much suppressed with respect to the vector one. At large energies their ratio becomes σ(B c ∗) σ(B c) ∼ 4 . The process of heavy quark recombination dominates in the production of B c(B c ∗) states. The fragmentation process b → B c comes into play at high p t values only, while its contribution remains nondominant.
