4 Jul 2001 | Subject: | nucl-th astro-ph hep-ph | Abstract: | Using effective field theory, we calculate the S-factor for the hep process in a totally parameter-free formulation. The transition operators are organized according to chiral counting, and their matrix elements are evaluated using the realistic nuclear wave functions obtained in the correlated-hyperspherical-harmonics method. Terms of up to next-to-next-to-next-to-leading order in heavy-baryon chiral perturbation theory are considered. Fixing the only parameter in the theory by fitting the tritium eta-decay rate, we predict the hep S-factor with accuracy better than sim 20 %. | Source: | arXiv, nucl-th/0107012 | Services: | Forum | Review | PDF | Favorites |
