Parallel session C3: Mesons in Matter 1
- Tetsuo Hyodo (Tokyo Metropolitan University)
Coherent pion photoproduction on nuclei is an efficient tool for studying nucleon density and determining neutron skin thickness. However, a reliable description of pion scattering and other medium effects is needed for these purposes. We build a universal model describing both pion scattering and photoproduction on spin-zero nuclei within the same framework. We develop second-order momentum...
The status of recent theoretical and experimental research related to the properties of the $\phi$ meson in nuclear matter is reviewed, focusing on observables that will be measured at the J-PARC E16 experiment, including dilepton and $K^+K^-$ decay modes and their angular distributions. The relation of these observables to fundamental properties of the strong interaction and nuclear matter,...
The scalar and the tensor glueballs ($J^{PC}=0^{++}$ and $2^{++}$) are, according to lattice results, the two lightest particle in the Yang-Mills sector of QCD. We study the scattering of two scalar and two tensor glueballs starting from the well known dilaton potential, that depends on a single dimentionful parameter, denoted as $\Lambda_G$. Upon a proper choice of the unitarization scheme,...
