Investigation of momentum space correlations of particles produced in high energy reactions requires taking final state interactions into account, a crucial point of any such analysis. Coulomb interaction between charged particles is the most importa...

We review a series of unitarization techniques that have been used during the last decades, many of them in connection with the advent and development of current algebra and later of Chiral Perturbation Theory. Several methods are discussed like the...

$J/\psi$, a charmonium bound state made of a charm and an anti-charm quark, was discovered in the 1970s and confirmed the quark model. Because the mass of charm quarks is significantly above the quantum chromodynamics (QCD) scale ${\mathsf{\Lambda }}_{QCD}$, charmoni...

Within the framework of dispersion theory, we study the the processes $e^{+}{e}^{-}\to \varphi \left(2170\right)\to \varphi \pi \pi \left(K\overline{K}\right)$. The strong pion–pion final-state interactions, especially the $K\overline{K}$ coupled channel in the S wave, are taken in...

Satellite excitations and final state configuration interactions appear due to the many-electron correlations and result in a photoelectron spectrum complex final state structure instead of single lines corresponding to one-hole states. In the presen...

In neutrino event generators, for models for neutrino and electron scattering, only inclusive cross sections are implemented. When these models are used to describe a semi-inclusive cross section, the event generator attaches the hadron variables bas...

The role of initial state (ISI) and final state (FSI) ion–ion interactions in heavy-ion double-charge-exchange (DCE) reactions $A(Z,N)\to A(Z\pm 2,N\mp 2)$ are studied for double single-charge-exchange (DSCE) reactions given by sequentia...
