Muonium Lifetime and Heavy Quark Decays∗ (lessons Learned from Muonium)
When asked to speak at this Symposium honoring the distinguished scientific career of Vernon Hughes, I knew the word “muon” would have to appear in my title and some property of that particle would provide my theme. Indeed, everyone at Yale knows the answer to I.I. Rabi’s famous question, uttered when confirmation of the muon’s existence was announced: “Who ordered that?” It must have been Rabi...
متن کاملCharm meson radiative decays
Combining heavy quark effective theory and the chiral Lagrangian approach we investigate D meson radiative decays. First, we reanalyse D∗ → Dγ decays using heavy quark spin symmetry, chiral symmetry Lagrangian, but including also the light vector mesons. Then, we calculate branching ratios D → V γ. We make some comments on the Cabbibo suppressed decays D → ρ/ωγ and the branching ratios of D → P...

متن کاملSemileptonic B Meson Decays
We review some of the most important topics in the semileptonic decays of B mesons, with emphasis on recent results from CLEO and LEP. We discuss the current data samples, inclusive and exclusive semileptonic decay branching fractions, and form factor measurements in the context of HQET.
متن کاملA Constituent Quark-Meson Model for Heavy Meson Decays
I describe a model for heavy meson decays based on an effective quark-meson lagrangian. I consider the heavy mesons S with spin and parity J = (1, 0), H with J = (1, 0) and T μ with J = (2, 1), i.e. S and P wave heavy-light mesons. The model is constrained by the known symmetries of QCD in the mQ → ∞ for the heavy quarks and chiral symmetry in the light quark sector. Using a very limited number...
