Branching Fractions for D0 -> K+K- and D0 -> pi+pi-, and a Search for CP Violation in D0 Decays

The Fermilab E791 Collaboration, E. M. Aitala

Using the large hadroproduced charm sample collected in experiment E791 at Fermilab, we have measured ratios of branching fractions for the two-body singly-Cabibbo-suppressed charg…

Study of Semileptonic Decays of B Mesons to Charmed Baryons

CLEO Collaboration, G. Bonvicini et al

Using data collected by the CLEO II detector at the center-of-mass energy on or near the Upsilon(4S) resonance, we have determined the 90% confidence level upper limit B(Bbar --> L…

Observation of the Radiative Decay

CLEO Collaboration, J. Bartelt et al

We have observed a signal for the decay D*+ -> D+ gamma at a significance of 4 standard deviations. From the measured branching ratio B(D*+ -> D+ gamma)/B(D*+ -> D+ pi0)=0.055 +- 0…

Polarised Quark Distributions in the Nucleon from Semi-Inclusive Spin Asymmetries

Spin Muon Collaboration

We present a measurement of semi-inclusive spin asymmetries for positively and negatively charged hadrons from deep inelastic scattering of polarised muons on polarised protons and…
