摘要：
The ratios of B-d and B-s meson decay constant have been estimated using the variational method in conjunction with the relativistic Hamiltonian of the heavy meson in the framework of the statistical model. The ratio of CKM matrix elements \upsilon(td)/upsilon(ts)\ has been extracted from B-omicron-B-omicron mixing using the estimated decay constants and ratio of B-d and B-s mass differences, The results are found to be in good agreement with the existing theoretical and experimental predictions.
