摘要：

In this work, we study higher Bc mesons to the L = S, P, D, F, G multiplets using the Cornell potential model, which takes account of the screening effect. The calculated mass spectra of Bc states are in reasonable agreement with the present experimental data. Based on the spectroscopy, partial widths of all allowed radiative transitions and strong decays of each state are also evaluated by applying our numerical wave functions. Comparing our results with the former results, we point out the difference among various models and derive new conclusions obtained in this paper. Our theoretical results are valuable for searching more Bc mesons in experiments.
