Phys. Rev. Lett. 101, 102002 (2008) [4 pages]Factorization Theorems for Exclusive Heavy-Quarkonium ProductionReceived 26 May 2008; published 4 September 2008 We outline the proofs of the factorization theorems for exclusive two-body charmonium production in B-meson decay and e+e- annihilation to all orders in perturbation theory in quantum chromodynamics. We find that factorized expressions hold up to corrections of order mc/mb in B-meson decay and corrections of order mc2/s in e+e- annihilation, where mc is the charm-quark mass, mb is the bottom-quark mass, and √s is the e+e- center-of-momentum energy. © 2008 The American Physical Society URL:
