4 Jul 2002 | Journal: | Phys.Rev. D66 (2002) 031901 | Subject: | hep-ph | Affiliation: | U. Innsbruck), R.J. Crewther (U of Adelaide & U. of Durham), F.M. Steffens (IFT, Sao Paulo) and A.W. Thomas (CSSM, U. of Adelaide | Abstract: | We combine Witten’s renormalization group with the matching conditions of Bernreuther and Wetzel to calculate at next-to-leading order the complete heavy-quark contribution to the neutral-current axial-charge measurable in neutrino-proton elastic scattering. Our results are manifestly renormalization group invariant. | Source: | arXiv, hep-ph/0207071 | Services: | Forum | Review | PDF | Favorites |
