“…Just as in all other potential models, we too cannot expect to obtain precise meson masses for all the states. So we adjust the V 0 value in our potential to a new value i.e -0.01545 GeV so as to set the B c (2s) mass equal to the observed value as done by T.Wang et al in their analysis based on the instantaneous approximated Bethe-Salpeter approach [27]. With the newly adjusted value of V 0 and other relevant input parameters (22,23), we predict the mass of meson states: B * c (2s), B c (2s), B * c (3s) and B c (3s) as:…”

“…Since rigorous field theoretic formulation with a first principle application of QCD for reliable estimation of the hadronic matrix element has not so far been possible, most of the theoretical attempts take resort to phenomenological approaches to probe the non-perturbative QCD dynamics. Different theoretical attempts [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] including various versions of potential models based on Bethe-Salpeter (BS) approach, light front quark (LFQ) model and QCD sum rules etc. have been employed to evaluate the B c -spectrum and predict the mass, lifetime and decay widths of the ground and excited B c and B * c meson states.…”

We study M1-transitions involving mesons: B c (1s), B * c (1s), B c (2s), B * c (2s), B c (3s) and B * c (3s) in the relativistic independent quark (RIQ) model based on a flavor independent average potential in the scalar-vector harmonic form. The transition form factor for B * c → B c γ is found to have analytical continuation from spacelike to physical timelike region. Our predicted coupling constant g B * c Bc = 0.34 GeV −1 and decay width Γ(B * c → B c γ) = 23 eV agree with other model predictions. In view of possible observation of B c and B * c s-wave states at LHC and Z-factory and potential use of theoretical estimate on M1-transitions, we investigate the allowed as well as hindered transitions of orbitally excited B c -meson states and predict their decay widths in overall agreement with other model predictions. We consider the typical case of B * c (1s) → B c (1s)γ, where our predicted decay width which is found quite sensitive to the mass difference between B * c and B c mesons may help in determining the mass of B *

“…To estimate the production rates in experiments, the production of the excited B c states were often discussed in the literature [40][41][42][43][44][45][46][47][48][49][50][51][52][53]. As the dominant decay modes, the electromagnetic transitions of the low-lying B c states were also widely estimated in the literature [7][8][9][10][11][12][13][14][15][16][54][55][56][57][58]. However, the studies of the OZIallowed strong decays for the high-lying B c states are confined only to a few calculations [17,18,59,60].…”

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:

The Concise Guide to PHARMACOLOGY 2021/22 is the fifth in this series of biennial publications. The Concise Guide provides concise overviews, mostly in tabular format, of the key properties of nearly 1900 human drug targets with an emphasis on selective pharmacology (where available), plus links to the open access knowledgebase source of drug targets and their ligands (https://www.guidetopharmacology.org), which provides more detailed views of target and ligand properties. Although the Concise Guide constitutes over 500 pages, the material presented is substantially reduced compared to information and links presented on the website. It provides a permanent, citable, point‐in‐time record that will survive database updates. The full contents of this section can be found at http://onlinelibrary.wiley.com/doi/bph.15543. Transporters are one of the six major pharmacological targets into which the Guide is divided, with the others being: G protein‐coupled receptors, ion channels, nuclear hormone receptors, catalytic receptors and enzymes. These are presented with nomenclature guidance and summary information on the best available pharmacological tools, alongside key references and suggestions for further reading. The landscape format of the Concise Guide is designed to facilitate comparison of related targets from material contemporary to mid‐2021, and supersedes data presented in the 2019/20, 2017/18, 2015/16 and 2013/14 Concise Guides and previous Guides to Receptors and Channels. It is produced in close conjunction with the Nomenclature and Standards Committee of the International Union of Basic and Clinical Pharmacology (NC‐IUPHAR), therefore, providing official IUPHAR classification and nomenclature for human drug targets, where appropriate.
