Uncertainties in Estimating Hadronic Production of the Meson Bc and Comparisons between TEVATRON and LHC

Abstract

The uncertainties in estimating the hadronic production of the Bc meson are studied under the framework of the complete αs4 approach of the perturbative QCD and the gluon-gluon fusion mechanism. Quantitative comparisons on the production at TEVATRON and LHC are made. Considering the detectors at TEVATRON and LHC, we have also estimated the production with proper kinematic cuts. Based on the results, we conclude that the experimental studies of the Bc meson at the two colliders will be complimentary and stimulative. We find that as c.m. energy is increasing from RUN-I to RUN-II at TEVATRON, the production cross-section increases about 20%.
