Title: X(1576) and the final state interaction effect

Abstract

We study whether the broad peak X(1576) observed by BES Collaboration arises from the final state interaction effect of {rho}(1450 1700) decays. The interference effect could produce an enhancement around 1540 MeV in the K{sup +}K{sup -} spectrum with typical interference phases. However, the branching ratio B[J/{psi}{yields}{pi}{sup 0}{rho}(1450 1700)]{center_dot}B[{rho}(1450 1700){yields}K{sup +}K{sup -}] from the final state interaction effect is far less than the experimental data.

  • The angular correlation between photons of about 1210 kev and the 244K conversion electrons was determined. The high-energy photons were also recorded in coincidence with the 244--kev photons. The multipolarity of the 1210and 1300- kev transitions was determined. (R.E.U.)
  • Recently, the BES Collaboration observed a broad resonant structure X(1576) with a large width being around 800 MeV and assigned its J{sup PC} number to 1{sup --}. We show that the isospin of this resonant structure should be assigned to 1. This state might be a molecule state or a tetraquark state. We study the consequences of a possible K*(892)-{kappa} molecular interpretation. In this scenario, the broad width can easily be understood. Carefully searching this resonant structure in the J/{psi}{yields}{pi}{sup +}{pi}{sup -}{pi}{sup 0} and J/{psi}{yields}K{sup +}K{sup -}{pi}{sup +}{pi}{sup -}{pi}{sup 0} decays should be important for understanding the structure of X(1567)
  • We consider the x-ray resonant Raman scattering (RRS) in La in the whole M{sub 4,5} region ending with a state with a 4p hole, along the sequence 3d{sup 10}4f{sup 0}{r_arrow}3d{sup 9}4f{sup 1}{r_arrow}3d{sup 10}4p{sup 5}4f{sup 1}. The final state configuration mixes with that with two 4d holes, i.e., 3d{sup 10}4d{sup 8}4f{sup n+2} having almost the same energy. Thus RRS must be described by introducing final-state configuration interaction (CI) between states with one 4p hole and with two 4d holes. This approach allows detailed experimental data on La metal to be interpreted on the basis of a purely ionic approach. It ismore » shown that the inclusion of CI is crucial and has very clear effects. The calculations with the Kramers-Heisenberg formula describe all measured spectral features appearing in the strict Raman regime, i.e., dispersing with the incident photon energy. In the experiment also a nondispersive component is present when the excitation energy is greater than about 2 eV above the M{sub 5} peak. The shape and position of this component is well accounted for by a model based on all possible partitions of the excitation energy between localized and extended states. However the intensity of the nondispersive component is greater in the measurements, suggesting a rearrangement in the intermediate excited state. The comparison of ionic calculations with the metal measurements is legitimate, as shown by the comparison between the measurements on La metal and on LaF{sub 3} with M{sub 5} excitation giving the same spectrum within the experimental accuracy. Moreover the experiment shows that the final lifetime broadening is much greater in the final states corresponding to lower outgoing photon energies than in the states corresponding to higher outgoing photon energies.« less
  • From analysis of experimental data on quasielastic scattering of high energy electrons by the nuclei /sup 6/Li, /sup 7/Li, and /sup 9/Be we have obtained the dependence on momentum transfer of the position of the quasielastic scattering peak for scattering of electrons by the nucleus relative to the free-proton elastic-scattering peak. This dependence is related to the effect of the final-state interaction on the quasielastic scattering cross section.
  • The model of independent single-particle sources is used to study the effect of the s-wave interaction in the final state on the correlations of two particles with small relative momenta. The contribution of the final-state interaction to the correlation function is detemined by the scattering amplitude and the space-time dimensions of the generation region. The case of two neutrons is studied in detail. It is shown that at a scale of 2--3 F the effect of the neutron interaction significantly exceeds the interference correlations of noninteracting identical particles with spin 1/2. The nature of the correlations is discussed for themore » pairs K/sup 0//sub S/K/sup 0//sub S/, ..pi../sup +/..pi../sup +/(..pi../sup -/..pi../sup -/), np, and ..pi../sup +/..pi../sup -/. Formulas are obtained which takes into account the combined contribution of the Coulomb and short-range forces. The effect of the Coulomb interaction on the correlations of two protons is studied.« less
