Higher-Twist Distribution Amplitudes of the K Meson in QCD
Patricia Ball, V. M. Braun, A. Lenz
We present a systematic study of twist-3 and twist-4 light-cone distribution amplitudes of the K meson in QCD. The structure of SU(3)-breaking corrections is studied in detail. Non…
Exclusive Semileptonic and Rare B-Meson Decays in QCD
Patricia Ball, V. M. Braun
We present the first complete results for the semileptonic and rare radiative form factors of B-mesons weak decay into a light vector-meson (rho, omega, K*, phi) in the light-cone…
Resummation of Running Coupling Effects in Semileptonic B Meson Decays and Extraction of
P. Ball, M. Beneke, V. M. Braun
We present a determination of from semileptonic B decays that includes resummation of supposedly large perturbative corrections, originating from the running of the stro…
Radiative Corrections to Nonleptonic Inclusive B Decays and the Semileptonic Branching Ratio of B Mesons
P. Ball
We calculate the radiative corrections to the nonleptonic inclusive B decay mode taking into account the charm quark mass. The corrections increase the decay rate by (4…
The Mass Definition in Hqet and a New Determination of V
P. Ball, U. Nierste
Positive powers of the mass parameter in a physical quantity calculated with the help of heavy quark effective theory originate from a Wilson coefficient in the matching of QCD and…
Quenched Staggered Spectrum at Beta=6.0, 6.2 and 6.4
Greg Kilcup
We give a preliminary report on the hadron spectrum on an ensemble of quenched lattices at values of 6.0, 6.2 and 6.4, using staggered fermions and collaborators Rajan Gupta an…
