Quark model study of the semileptonic B -> pi decay
Quark model study of the semileptonic B -> pi decay
The semileptonic decay B→π is studied starting from a simple quark model and taking into account the effect of the B* resonance. A novel, multiply subtracted, Omnès dispersion relation has been implemented to extend the predictions of the quark model to all physical q2 values. We find |Vub| = 0.0034 ± 0.0003(exp.) ± 0.0007(theory), in good agreement with experiment.

Abstract
The semileptonic decay B→π is studied starting from a simple quark model and taking into account the effect of the B* resonance. A novel, multiply subtracted, Omnès dispersion relation has been implemented to extend the predictions of the quark model to all physical q2 values. We find |Vub| = 0.0034 ± 0.0003(exp.) ± 0.0007(theory), in good agreement with experiment.
