A Precise Determination of from Lattice QCD

C. T. H. Davies, K. Hornbostel, G. P. Lepage +3

We present a new determination of the QCD strong coupling constant based on precise lattice calculations of the spectrum. The largest systematic uncertainty in previous such de…

Rigorous QCD Analysis of Inclusive Annihilation and Production of Heavy Quarkonium

Geoffrey T. Bodwin, Eric Braaten, G. Peter Lepage

A rigorous QCD analysis of the inclusive annihilation decay rates of heavy quarkonium states is presented. The effective-field-theory framework of nonrelativistic QCD is used to se…

Effective Lagrangian Approach to Weak Radiative Decays of Heavy Hadrons

Hai-Yang Cheng, Chi-Yee Cheung, Guey-Lin Lin +3

Motivated by the observation of the decay by CLEO, we have systematically analyzed the two-body weak radiative decays of bottom and charmed hadrons. There e…

Measurement of the Branching Fraction for D^+ \to K^- π^+ π^+

The CLEO collaboration

Using the CLEO-II detector at CESR we have measured the ratio of branching fractions, ${\cal B}(D^+\rightarrow K^- π^+ π^+)/{\cal B}(D^0 \rightarrow K^-π^+) = 2.35 \pm 0.16 \pm 0.1…

Measurement of Cabibbo Suppressed Decays of the Lepton

The CLEO Collaboration

Branching ratios for the dominant Cabibbo-suppressed decays of the lepton have been measured by CLEO~II in annihilation at CESR (~GeV) using kaons…

Study of the Decay $Λ_c \to Λl^+ ν_{l}

The CLEO Collaboration

Using the CLEO II detector at CESR, we observe 500 pairs consistent with the semileptonic decay . We measure $σ(e^+ e^- \to Λ_c X) \dot {cal B}(Λ_c^+ \to…

Observation of a New Charmed Strange Meson

The CLEO Collaboration

Using the CLEO-II detector, we have obtained evidence for a new meson decaying to . Its mass is {}~MeV/ and its width is $16^{+5}…

Critical Exponents without the Epsilon Expansion

Mark Alford

We argue that the sharp-cutoff Wilson renormalization group provides a powerful tool for the analysis of second-order and weakly first-order phase transitions. In particular, in a…

Improved Theory of the Muonium Hyperfine Structure

T. Kinoshita, M. Nio

Terms contributing to the hyperfine structure of the muonium ground state at the level of few tenths of kHz have been evaluated. The radiative correction has been calcul…

Corrections to Chiral Dynamics of Heavy Hadrons: SU(3) Symmetry Breaking, (with some minor corrections)

Hai-Yang Cheng, Chi-Yee Cheung, Guey-Lin Lin +3

In previous publications we have analyzed the strong and electromagnetic decays of heavy mesons and heavy baryons in a formalism which incorporates heavy-quark and chiral symmetrie…
