Color-Octet Fragmentation and the psi' Surplus at the Tevatron
Eric Braaten, Sean Fleming
The production rate of prompt 's at large transverse momentum at the Tevatron is larger than theoretical expectations by about a factor of 30. As a solution to this puzzle, we…
Perturbative QCD Fragmentation Functions as a Model for Heavy-Quark Fragmentation
E. Braaten, K. Cheung, S. Fleming +1
The perturbative QCD fragmentation functions for a heavy quark to fragment into heavy-light mesons are studied in the heavy-quark limit. The fragmentation functions for S-wave pseu…
Radiative Corrections to Quarkonium Decays: From a Model to a Rigorous Theory
Eric Braaten
Most previous calculations of the annihilation decay rates of heavy quarkonium were based on factorization assumptions that were unproven and, in some cases, even incorrect. The re…
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…
