Low-Mass Baryon-Antibaryon Enhancements in B Decays | | Jonathan L. Rosner
; | | Date: |
10 Mar 2003 | | Journal: | Phys.Rev. D68 (2003) 014004 | | Subject: | hep-ph | | Abstract: | The nature of low-mass baryon-antibaryon enhancements seen in B decays is explored. Three possibilities include (i) states near threshold as found in a model by Nambu and Jona-Lasinio, (ii) isoscalar states with $J^{PC} = 0^{pm +}$ coupled to a pair of gluons, and (iii) low-mass enhancements favored by the fragmentation process. Ways of distinguishing these mechanisms using angular distributions and flavor symmetry are proposed. | | Source: | arXiv, hep-ph/0303079 | | Services: | Forum | Review | PDF | Favorites | |
