Order m alpha^8 Contributions to the Decay Rate of Orthopositronium

P. Labelle, G. P. Lepage, U. Magnea

We discuss how contributions to the order orthopositronium decay rate can be separated into two categories, one due to relativistic momenta and calculable in ter…

Radiatively-Induced First-Order Phase Transitions: The Necessity of the Renormalization Group

Mark Alford, John March-Russell

We advocate a (Wilson) renormalization-group (RG) treatment of finite-temperature first-order phase transitions, in particular those driven by radiative corrections such as occur i…

Corrections to Chiral Dynamics of Heavy Hadrons: (I) 1/M Correction

H. Y. Cheng, C. Y. Cheung, G. L. Lin +3

In earlier publications we have analyzed the strong and radiative decays of heavy hadrons in a formalism which incorporates both heavy-quark and chiral symmetries. In particular, w…

Heavy Quark and Chiral Symmetry Predictions for Semileptonic Decays B->D(D*),pi,l,nu

H-Y Cheng, C-Y Cheung, W. Dimm +4

We study in detail the prediction for the semileptonic decays by heavy quark and chiral symmetry. The branching ratio for $\bar{B} \to D π\ell \ba…

Metastability in Two Dimensions and the Effective Potential

M. Alford, M. Gleiser

We study analytically and numerically the decay of a metastable phase in (2+1)-dimensional classical scalar field theory coupled to a heat bath, which is equivalent to two-dimensio…
