16 Jul 2015 | | Abstract: | The pentaquark component is included in the proton wave functions to study
phi meson production proton-antiproton annihilation reactions. With all
possible configurations of the uuds subsystem proposed for describing the
strangeness spin and magnetic moment of the proton, we estimate the branching
ratios of the annihilation reactions at rest proton-antiproton to phi + X
(X=pi, eta, rho, omega) from atomic proton-antiproton S- and P-wave states by
using effective quark line diagrams incorporating the 3P0 model. The best
agreement of theoretical prediction with the experimental data is found when
the pentaquark configuration of the proton wave function takes the flavor-spin
symmetry, [4]_FS [22]_F [22]_S. | | Source: | arXiv, 1507.4503 | | Services: | Forum | Review | PDF | Favorites | |
