Muonium Decay
Andrzej Czarnecki, G. Peter Lepage, William J. Marciano
Modifications of the mu+ lifetime in matter due to muonium (M = mu+ e-) formation and other medium effects are examined. Muonium and free mu+ decay spectra are found to differ at O…
Flavor-Symmetry Restoration and Symanzik Improvement for Staggered Quarks
G. Peter Lepage
We resolve contradictions in the literature concerning the origins and size of unphysical flavor-changing strong interactions generated by the staggered-quark discretization of QCD…
Redesigning Lattice QCD
G. Peter Lepage
There has been major progress in recent years in the development of improved discretizations of the QCD action, current operators, etc for use in numerical simulations that employ…
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…
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…
P-Wave Charmonium Production in B-Meson Decays
Geoffrey T. Bodwin, Eric Braaten, Tzu Chiang Yuan +1
We calculate the decay rates of mesons into P-wave charmonium states using new factorization formulas that are valid to leading order in the relative velocity of the charmed qu…
