“…[11]. The strong decay widths of B c (3 1 S 0 ) and B c (3 3 S 1 ) predicted by us are comparable to those predicted in recent works [18,59]. Both B c (3 1 S 0 ) and B c (3 3 S 1 ) might be broad states with a width of ∼ 100 MeV.…”

“…The results for the M1 transitions, E1 dominant transitions and strong decays of the 3S -wave states are given in Tables III, VII and X, respectively. There are only a few works about the radiative and strong decay properties of the 3S -wave states [11,18,59,60]. The M1 transitions of the 3S -wave states roughly agree with the predictions in Ref.…”

Using the newly measured masses of B c (1S ) and B c (2S ) from the CMS Collaboration and the 1S hyperfine splitting determined from the lattice QCD as constrains, we calculate the B c mass spectrum up to the 6S multiplet with a nonrelativistic linear potential model. Furthermore, using the wave functions from this model we calculate the radiative transitions between the B c states within a constituent quark model. For the higher mass B c states lying above DB threshold, we also evaluate the Okubo-Zweig-Iizuka (OZI) allowed two-body strong decays with the 3 P 0 model. Our study indicates that besides there are large potentials for the observations of the low-lying B c states below the DB threshold via their radiative transitions, some higher mass B c states, such as B c (2 3 P 2 ), B c (2 3 D 1 ), B c (3 3 D 1 ), B c (4 3 P 0 ), and the 1F-wave B c states, might be first observed in their dominant strong decay channels DB, DB * or D * B at the LHC for their relatively narrow widths.PACS numbers:

“…We summarize the properties of these states in Table I where we quote the Particle Data Group (PDG) values, averaged over charge states [18]. At the same time, there have been numerous theoretical calculations of the properties of these states [8,[19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. In this brief note we will compare the predictions of a particular quark model [7,8] to the measured properties of the recently observed excited bottom mesons.…”

Excited B-mesons have been observed by the D0, CDF, LHCb and CMS experiments. We use the predictions of the relativized quark model to make quark model spectroscopic assignments for these states. We identify the B * 2 (5747) and B1 (5721) as the B * 2 [1 3 P2] and B1[1P1] states and the B * s2 (5840) and Bs1(5830) as the B * s2 [1 3 P2] and Bs1[1P1]states. More information is needed to identify the BJ (5970) and BJ (5840) states and we suggest a number of measurements to make this identification: the determination of their J P quantum numbers and either confirming or ruling out their decays to the Bπ final state. With the current information available we believe it most likely that the BJ (5970) is the B * [2 3 S1] state, with the BJ (5840) needing confirmation.PACS numbers:

“…This work employed SHO mesonic wavefunctions with a fixed Gaussian width. Two additional papers have computed B and D meson spectra with the Godfrey-Isgur model [26,27]. They have also calculated strong decays using a very similar method to that presented here; the main difference is that the latter group incorporated a quark form factor in the 3 P 0 vertex to suppress high energy decay modes and used SHO mesonic wavefunctions with a single Gaussian width.…”

Properties of bottom and bottom-strange mesons are computed in two relativized quark models. Model masses and wavefunctions are used to predict radiative transition rates and the 3 P0 quark pair creation model is used to compute strong decay widths. A comparison to recently observed bottom and bottom-strange states is made. We find that there are numerous excited B and Bs mesons that have relatively narrow widths and significant branching ratios to simple final states such as Bπ, B * π, BK, and B * K that could be observed in the near future.
