Abstract

We predict the masses of the lowlying BcB_c mesons with JP=0,1,0+,1+,2+J^P = 0^-,\,1^-,\,0^+,\,1^+,\,2^+, using a flavor dependent interaction pattern which gives an unified successful description of the light, heavy-light and heavy mesons and is also appliable to the radial excited heavy mesons. The errors are controlled carefully. With the errors from the RL approximation subduced, our predictions are consistent with the lQCD and quark model results, which supports strongly that the flavor dependent interaction pattern is reasonable. Our predictions provide significant guides to the experiment search of the BcB_c mesons.
