15 Dec 1999 | | Journal: | PiN Newslett. 15 (1999) 118-122 | | Subject: | nucl-th | | Affiliation: | Lab for Nuclear Science, M.I.T., Cambridge, MA ; Dept. of Physics, V.P.I., Blacksburg, VA ; Dept. of Physics, The George Washington University, Washington, D.C. | | Abstract: | A new result for the nucleon sigma term from an updated pion-nucleon partial-wave and dispersion relation analysis of the Virginia Polytechnic Institute (now George Washington University) group is discussed. Using a method similar to that of Gasser, Leutwyler, Locher, and Sainio, we obtain Sigma=90 +/- 8 MeV (preliminary), in disagreement with the canonical result 64 +/- 8 MeV, but consistent with expectations based on new information on the $pi$NN coupling constant, pionic atoms, and the Delta resonance width. | | Source: | arXiv, nucl-th/9912034 | | Services: | Forum | Review | PDF | Favorites | |
