Oscillation frequency of B and B mesons in a QCD potential model with relativistic effect

Abstract

Wavefunction at the origin with the incorporation of relativistic effect leads to singularity in a specific potential model. To regularise the wavefunction, we introduce a short distance scale here and use it to estimate masses and decay constants of Bd and Bs mesons within the QCD potential model.These values are then used to compute the oscillation frequency ΔmB of Bd and Bs mesons. The values are found to be in good agreement with experiment and other theoretical values.
