We succeed in reproducing the ℓ = 1 B mesons B1(5720), B*2(5745), and B*s2(5839) that were recently reported by D0 and CDF, using our semi-relativistic quark potential model, which also succeeds in predicting the mass spectra of the narrow DsJ, as well as broad D*0(0+) and D′1(1+) particles observed a couple of years ago. The mass of higher excited states (ℓ = 1, 2) of B and Bs mesons, which have not yet been observed, is also predicted to first order in p/mb with the internal quark momentum p and the b quark mass mb. We find that the corresponding BsJ are below the BK/B*K threshold and should have narrow decay widths, contrary to most other predictions. Also, already established states (ℓ = 0 and ℓ = 1) of D, Ds, B, and Bs heavy mesons are simultaneously reproduced in good agreement with experimental data, within one percent accuracy. To calculate these D/Ds and B/Bs heavy mesons, we use different values of the strong coupling, αcs and αbs, respectively.
