    • Abstract

       

      The charmless nonleptonic decay modes $B \rightarrow f_{0} K(\pi)$ involving a scalar and a pseudoscalar meson in the final state are studied. The scalar meson $f_{0}$ is considered as a $q\bar{q}$ state, as favored by some recent studies. Using the generalized factorization approach, the branching ratios and CP violation parameters are computed for these modes. The form factors are calculated using the results from relativistic light front quark model and the ISGW2 model. It is found that the direct CP violation parameters in these modes are small. However, the obtained branching ratios are not in agreement with the experimental data. Therefore, these modes may be considered as possible probes for new physics.
