Analyticity, renormalization, and evolution of the soft-quark function
Geoffrey T. Bodwin, June-Haak Ee, Jungil Lee +1
We compute the renormalization and evolution of the soft-quark function that appears in the factorization theorem for Higgs-boson decays to two photons through a -quark loop. Ou…
Inclusive and production in decay at in nonrelativistic QCD factorization
Zhi-Guo He, Bernd A. Kniehl, Xiang-Peng Wang
We study and inclusive production in decay within the framework of nonrelativistic-QCD (NRQCD) factorization. In the latter case, for which no experimental data exi…
Pseudoscalar Quarkonium+gamma Production at NLL+NLO accuracy
Hee Sok Chung, June-Haak Ee, Daekyoung Kang +3
We consider the exclusive pseudoscalar heavy-quarkonium (eta_{b,c}) production in association with a photon at future lepton colliders where the collider energies of O(10^2) GeV ar…
Breakdown of NRQCD Factorization in Processes Involving Two Quarkonia and its Cure
Zhi-Guo He, Bernd A. Kniehl, Xiang-Peng Wang
We study inclusive processes involving two heavy quarkonia in nonrelativisitic QCD (NRQCD) and demonstrate that, in the presence of two P-wave Fock states, NRQCD factorization brea…
Inclusive production in decay at in NRQCD factorization
Zhi-Guo He, Bernd A. Kniehl, Xiang-Peng Wang
Inclusive production from decay is studied within the framework of nonrelativistic QCD (NRQCD) factorization at leading order in , which include…
