Measurement of CP observables in B± → DK± and B± → Dπ± with D → K0 SK±π∓ decays

Measurement of the branching fractions for B+ -> D+ D- K+, B+ -> D- D+ K+, and B0 -> D*- D0 K+ decays

Pavol Stefko

Charmed hadron spectroscopy is a quickly progressing field that has enjoyed a growing interest in recent years from both theorist and experimentalists. Open-charmed hadrons consist of a heavy

Search for B+ -> mu(+)nu(mu) and B+ -> mu N+ with inclusive tagging

Olivier Schneider, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Donghyun Kim

We report the result for a search for the leptonic decay of B+ -> mu(+)nu mu using the full Belle dataset of 711 fb(-1) of integrated luminosity at the gamma(4S) resonance. In the Standard Model leptonic B-meson decays are helicity and Cabibbo-Kobayashi-Ma ...
