Meson-Nucleon Interactions: Meson-Nucleon Interactions
- Philipp Gubler (JAEA)
The pion-pion scattering amplitude is required for the calculation of the pion form factor in the timelike region from Lattice QCD. We present results from a recent lattice calculation of both quantities and discuss their impact on the lattice determination of the hadronic vacuum polarization contribution to $(g-2)_\mu$. These results pave the way towards computing the more complicated Delta...
Antikaon hydrogen atoms offer an ideal framework to study strong-interaction processes, allowing to perform experiments at vanishing relative energies between the antikaon and the nucleon, which will give access to the basic low-energy parameters, like the antikaon-nucleon scattering lengths. The antikaon hydrogen reaction is well understood from the recent results obtained from KpX at KEK,...
The $\omega$ meson is one of the important particles to describe the nucleon-nucleon interaction. Nevertheless, scattering between the omega meson and nucleon is not well established. Recently we have performed high precision photoproduction experiment of the $\omega$ meson from the proton near the threshold. The total cross sections are determined at incident energies ranging from 1.08 to...
Finite volume multiple-particle interaction is studied in a two-dimensional complex $\phi^4$ lattice model. The existence of analytical solutions to the $\phi^4$ model in two-dimensional space and time makes it a perfect model for the numerical study of finite volume effects of multi-particle interaction. The spectra from multiple particles are extracted from the Monte Carlo...
