Abstract

We calculate the ratio f(Bs)/f(Bd) by following the Oakes method which is based on chiral symmetry breaking, but we improve his calculationby performing the calculation of the factor [0\(b) over bar gamma(5)s\B-s]/[0\(b) over bar gamma(5)d\B-d] in a mock meson model. In this calculation we improved the mock meson model by using a value of the parameter beta which is obtained by the variational method in the relativistic quark model. We also calculate f(Ds)/fD(d), and then (f(Bs)/f(Bd))/(f(Ds)/f(Dd)). In this method we also obtain the ratio f(Bs)/f(Ds) and f(Bd)/f(Dd) which are important for the knowledge of CP violation and B-(B) over bar mixing.
