Final state interaction effects in B{sup 0} → J/ψπ{sup 0} decay
- Semnan University, Physics Department (Iran, Islamic Republic of)
In this research the exclusive decay of B{sup 0} → J/ψπ{sup 0} is calculated by QCD factorization (QCDF) method and final-state interaction (FSI). First, the B{sup 0} → J/ψπ{sup 0} decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the B{sup 0} → J/ψπ{sup 0} decay. For this decay, the D{sup +}D{sup −}* and D{sup 0}<##> $$ /bar D^{0*} $$ D-bar {sup 0∗} via the exchange of D{sup −}, D{sup −}* and <##> $ /bar D^0 $$ D-bar {sup 0}, <##> $$ /bar D^{0*} $ D-bar {sup 0∗} mesons are chosen for the intermediate states. The above intermediate states are calculated by using the QCDF method. The experimental branching ratio of B{sup 0} → J/ψπ{sup 0} decay is (1.76 ± 0.16) × 10{sup −5} and our results calculated by QCDF and FSI are (0.56 ± 0.11) × 10{sup −5} and (1.3 ± 0.09) × 10{sup −5}, respectively.
