Vector Formfactors in Hard Pion Chiral Perturbation Theory.
(2011) In Nuclear Physics, Section B 846(2). p.145166 Abstract
 We use threeflavour hard pion Chiral Perturbation Theory (HPChPT) in both the heavy meson and a relativistic formulation to calculate the chiral logarithms m(2) log (m(2)/mu(2)) contributing to the formfactors of the B(s) > pi, K, eta and D(s) > pi, K, eta transitions at momentum transfer q(2) away from the endpoint q(max)(2) = (m(B)  m(M))(2). We compare our results with CLEO D > pi and D > K data. We also calculate the IsgurWise function of the B(s) > D(s) semileptonic decay away from the endpoint and the chiral logarithms for the pion and kaon electromagnetic formfactor. In twoflavour HPChPT we calculate the chiral logarithms for the pion vector and the scalar formfactors at s >> m(pi)(2). This allows... (More)

This allows us to test hard pion ChPT using the existing twoloop calculations for these quantities. (C) 2011 Elsevier B.V. All rights reserved. (Less)
