A possible resolution of the e+e- --> Nbar N puzzle | | Marek Karliner

12 Aug 2001 | | Journal: | eConf C010430 (2001) W10 | | Subject: | hep-ph | | Affiliation: | Tel-Aviv University | | Abstract: | We sketch some recent ideas proposed as the mechanism behind the puzzling experimental results on baryon-antibaryon production in e+e- annihilation close to threshold. The essential new point in the proposed mechanism is that it is a two-stage process, with a coherent state of pions serving as an intermediary between e+e- and the baryon-antibaryon system. Skyrmion-antiskyrmion annihilation is proposed as a concrete computational framework for a quantitative description of the baryon-antibaryon annihilation. We also point out the possible connection to similarly puzzling data on baryon-antibaryon production in photon-photon collision. | | Source: | arXiv, hep-ph/0108106 | | Services: | Forum | Review | PDF | Favorites | |
