Factorization in B -> K pi e+e- decays
Benjamin Grinstein, Dan Pirjol
We derive factorization relations for the transverse helicity amplitudes in the rare decays B-> Kπl+l- at leading order in Lambda/m_b, in the kinematical region with an energetic k…

A Precision Model Independent Determination of |Vub| from B -> pi e nu
M. Christian Arnesen, Ben Grinstein, Ira Z. Rothstein +1
A precision method for determining |Vub| using the full range in q^2 of B-> pi \ell nu data is presented. At large q^2 the form factor is taken from unquenched lattice QCD, at q^2=…
