Measurement of the Bc- meson production fraction and asymmetry in 7 and 13 TeV pp collisions
Abstract
The production fraction of the Bc- meson with respect to the sum of B- and B0 mesons is measured in both 7 and 13 TeV center-of-mass energy pp collisions produced by the Large Hadron Collider (LHC), using the LHCb detector. The rate, approximately 3.7 per mille, does not change with energy, but shows a transverse momentum dependence. The Bc- - Bc+ production asymmetry is also measured, and is consistent with zero within the determined statistical and systematic uncertainties of a few percent.
