| 英文摘要 | We investigate the o(alpha(s)upsilon(2)) correction to the process of pseudoscalar quarkonium decay to two photons in nonrelativistic qcd (nrqcd) factorization framework. the short-distance coefficient associated with the relative-order upsilon(2) nrqcd matrix element is determined to next-to-leading order in as through the perturbative matching procedure. some technical subtleties encountered in calculating the o(alpha(s)) qcd amplitude are thoroughly addressed. |
