The behavior of the masses, decay constants and widths of the B, D, and D* mesons in terms of the temperature is studied. The temperature dependency of the form factors responsible for such decays are also obtained. These temperature-dependent form factors are used to investigate the variation of the branching ratios with respect to the temperature. It is shown that the branching ratios do not change up to T/T-c = 0.3, however they start to diminish with increasing the temperature after this region and vanish at the critical or deconfinement temperature.eninfo:eu-repo/semantics/closedAccessQCDArticle10.1103/PhysRevD.81.0960018192-s2.0-77953159520N/AWOS:000278145100081Q1
