Near threshold enhancement of thepp¯mass spectrum inJ/Ψdecay

et al. 2005

We investigate the nature of the near-threshold enhancement in the pp invariant mass spectrum of the reaction J/Ψ→γpp reported recently by the BES Collaboration. Using the Jülich NN model we show that the mass dependence of the pp spectrum close to the threshold can be reproduced by the S-wave pp final state interaction in the isospin I=1 state within the Watson-Migdal approach. However, because of our poor knowledge of the NN interaction near threshold and of the J/Ψ→γpp reaction mechanism and in view of the controversal situation in the decay J/Ψ→π 0 pp, where no obvious signs of a pp final state interaction are seen, explanations other than final state interactions cannot be ruled out at the present stage.

“…Note that in Ref. [30], using the I = 1, 1 S 0p p potential from A(OBE) model [37,38] the authors reproduce thepp near-threshold spectrum (the peak) rather well for J/ψ → γpp decay based on the WM approximation. We then recalculate it, as a comparision, but now using the DWBA to take account of thepp FSI.…”

Abstract:After the observation of the strong near-threshold enhancement of proton-antiproton mass spectrum in J/ψ → γpp decay, lots of theoretical investigations have been available such as new resonance, the final-state pp interaction (FSI), pp bound state (or baryonium), glueball, or other exotic (tetra-quark) states. Here, we provide a short review on the current status, especially on the pertinent discussions concerning its relation to pp interaction, for which the emphasis is put on the recently constructed chiral potential.

“…However, it is desirable to study thep interactions with the nuclear medium within other theoretical approaches, such as microscopic models ofNN interaction based on mesonexchange models [3][4][5] or chiralNN interaction models [6,7]. Comparison between thesē NN interaction models could bring valuable information about in-mediump interactions in the direct confrontation with the data fromp atoms andp scattering off nuclei, as well as predictions forp-nuclear quasi-bound states.…”

Abstract. We studied thep interactions with the nuclear medium within the 2009 version of the ParisNN potential model. We constructed thep-nucleus optical potential using the Paris S -and P-wavepN scattering amplitudes and treated their strong energy and density dependence self-consistently. We considered a phenomenological P-wave term as well. We calculatedp binding energies and widths of thep bound in various nuclei. The P-wave potential has very small effect on the calculatedp binding energies, however, it reduces the corresponding widths noticeably. Moreover, the S -wave potential based on the Paris amplitudes supplemented by a phenomenological P-wave term yields thep binding energies and widths in very good agreement with those obtained within the RMF model consistent withp-atom data.
