Original · EN

In the heavy quark effective field theory of QCD, we analyze the order 1/mQ contributions to heavy to light vector decays. Light cone sum rule method is applied with including the effects of 1/mQ order corrections. We then extract |Vub| from B -> rho l nu decay up to order of 1/mQ corrections.
