Modern experimental facilities such as TJNAF and Julich are probing the baryonic structure and interactions at intermediate energies (∼ GeV), through electromagnetic and strong reactions involving high momentum transfer [1]. To describe the NN interaction in the intermediate energy range (∼ 300 MeV-1 GeV), particle production mechanisms have to be included. Relativistic effects became also impo...

Using a previously established effective Lagrangian model we describe anti-kaon induced reactions on the nucleon. The dominantly contributing channels in the cm-energy region from threshold up to 1.72 GeV are included (KN , πΣ, πΛ). We solve the Bethe-Salpeter equation in an unitary K-matrix approximation .

The Bethe-Salpeter equation plays a crucial role in understanding the physics of correlated fermions, relating to optical excitations solids as well resonances high-energy physics. Yet, it is notoriously difficult control numerically, typically requiring an effort that scales polynomially with energy and accuracy. This puts many interesting systems out computational reach. Using intermediate re...

We investigate coherent matter wave transport in isotropic 3D speckle potentials by using the Bethe–Salpeter equation and self-consistent theory of localization. This model constitutes an efficient tool to properly evaluate corrections Boltzmann diffusion taking into consideration quantum interference terms between multiple-scattering paths. calculate analytically numerically static current den...
