Helicity amplitudes in $$B \rightarrow D^{*} \bar{\nu } l$$ B→D∗ν¯l decay
Abstract We use a recent formalism of the weak hadronic reactions that maps the transition matrix elements at the quark level into hadronic matrix elements, evaluated with an elaborate angular momentum algebra that allows finally to write the weak matrix elements in terms of easy analytical formulas...
