| dc.description | We determine chiral loop corrections to the B meson decay amplitudes to positive and negative parity charmed mesons within a framework which combines heavy quark and chiral symmetries. We find that corrections due to states of opposite parity are competitive with the contributions arising from K and eta meson loops. Since lattice studies rely on the chiral behavior of the amplitudes we discuss the chiral limit of our results. We also comment on the extraction of 1/m_B, 1/m_D subleading form factors relevant for the studies of B_q to D_q tau nu decays, which are sensitive to possible helicity-suppressed new physics contributions. | |
