Absolute branching fraction measurements of exclusive D-0 semileptonic decays

Abstract

With the first data sample collected by the CLEO-c detector at the psi(3770) resonance we have studied four exclusive semileptonic decays of the D-0 meson. Our results include the first observation and absolute branching fraction measurement for D-0->rho(-)e(+)nu(e) and improved measurements of the absolute branching fractions for D-0 decays to K(-)e(+)nu(e), pi(-)e(+)nu(e), and K(*-)e(+)nu(e).
