Infrared Cutoff

Within the QCD factorization approach we compute the amplitudes for pure annihilation channels of B mesons decays into final states containing two pseudoscalar particles. These decays may be plagued by effects like nonperturbative physics and breaking of the factorization hypothesis and imply, at some extent, the introduction of an infrared cutoff in the calculation of amplitudes. We compute the decays with the help of infrared finite gluon propagators and coupling constants that were obtained in different solutions of the QCD Schwinger–Dyson equations. These solutions yield a natural cutoff for the amplitudes, and we argue that a systematic study of these B decays may provide a test for the QCD infrared behavior.

Babar Detector

The e+e- annihilation data recorded with the BABAR detector has been used to study B decays to [Formula: see text] and D*± mesons. The production fraction of inclusive [Formula: see text] and the corresponding momentum spectra have been determined. Exclusive decays [Formula: see text] have been identified with a partial reconstruction technique and their branching fractions have been measured. We also report branching fraction measurements for the exclusive hadronic modes B0 → D*- π+ and B0 → D*- ρ+.

Semileptonic B Decays

Using 250 pb-1 of data collected with the DØ detector in Run II of the Tevatron, the two narrow (L = 1) states, D1(2420) and [Formula: see text] have been observed in semileptonic decays of B mesons. Results on the D*+ π- decay mode are presented including a measurement of the branching fraction of B mesons to these states.
