Abstract

In this work we tried to predict the parameters of BcB^{*}_c meson. Simple assumptions gave us following parametres mBc=6329±10m_{B_{c}^{*}}=6329\pm 10 MeV and fBc=535.5±57.8f_{B_{c}^{*}}= 535.5\pm57.8 MeV (for ΛBc=2.26±0.14\Lambda_{B_{c}^{*}}=2.26\pm 0.14 GeV in covariant confined quark model). We calculated widths of radiative decays of BqB^*_{q} mesons, where q=u/d,s,cq=u/d,s,c and compared them with other theoretical works. It was shown that the width of the BcB_{c}^{*} meson very sensitive to the mass mBcm_{B_{c}^{*}} as expected and less to the size parameter ΛBc\Lambda_{B_{c}^{*}}.
