### Abstract

(Formula presented) violation from physics beyond the standard model is investigated in (Formula presented) decays: (Formula presented) The semileptonic B-meson decay to a D meson with an emission of a single pion is analyzed with heavy quark effective theory and chiral perturbation theory. In the decay process, we include various excited states as intermediate states decaying to the final hadrons, (Formula presented) (Formula presented) violation is implemented in a model independent way, in which we extend the leptonic current by including complex couplings of the scalar sector and those of the vector sector in extensions of the standard model. With these complex couplings, we calculate the (Formula presented)-odd rate asymmetry and the optimal asymmetry. We find that the optimal asymmetry is sizable and can be detected at (Formula presented) level with about (Formula presented)-meson pairs, for some reference values of new physics effects.
