dc.description.abstract | We discuss two-photon and hadronic production of Bc mesons in nonrelativistic
bound state approximation and to lowest order in the coupling
constants a and a s . It is shown that in photon-photon collisions, heavy
quark fragmentation is dominated by recombination of b and c quarks up
to the highest accessible transverse momenta. In contrast, in hadroproduction,
which at high energies mainly involves gluon-gluon collisions, the
fragmentation mechanism dominates at transverse momenta py > mRc,
providing a simple and satisfactory approximation of the complete 0(a ) )
results in the high-px regime. Contradictions in previous publications
on hadroproduction of Bc mesons are clarified. We also present predictions
for cross sections and differential distributions at present and future
accelerators. | pl_PL |
