Resolved photoproduction of the $B_c$ meson in electron-proton collisions
Abstract
We present a systematic study of meson photoproduction at electron--proton colliders within the framework of nonrelativistic QCD (NRQCD) factorization. In addition to the dominant direct channel , we include resolved contributions initiated by and subprocesses. Total cross sections and transverse-momentum distributions are calculated for several collider configurations, including HERA, LHeC, FCC-, and EIC. The numerical results show that the direct channel provides the leading contribution over the entire kinematic range. However, the resolved channel yields a non-negligible correction, reaching the level of in the low- region where most events are produced, and it becomes increasingly important at higher collision energies. The channel is found to be numerically insignificant.
