A workable basis of quark configurations $s^3$, $s^2p$ and $sp^2$ at light front has been constructed to describe the high-$Q^2$ behavior of transition form factors and helicity amplitudes in the electroproduction of the lightest nucleon resonances,

We suggest a description of the beam asymmetry in $p \bar p$ and $\Lambda \bar \Lambda$ photoproduction off the proton $\vec\gamma + p \to p \bar p + p$ and $\vec\gamma + p \to \Lambda \bar\Lambda + p$, takes into account the contribution of the scal

We suggest a theoretical framework for the description of double photon and proton-antiproton photoproduction off the proton gamma + p -> 2 gamma + p and gamma + p -> antip + p + p which takes into account the contribution of the scalar mesons f0(137

A relativistic light-front quark model is used to describe both the elastic nucleon and nucleon-Roper transition form factors in a large Q2 range, up to 35 GeV2 for the elastic and up to 12 GeV2 for the resonance case. Relativistic three-quark config

The Roper resonance is considered as a mixed state of a three-quark core configuration and a hadron molecular component N+sigma. Based on this ansatz we study electroproduction of the Roper resonance. The strong and electromagnetic couplings induced

We study the p(e,e' pi+)n reaction in the framework of an effective Lagrangian approach including nucleon, pi and rho meson degrees of freedom and show the importance of the rho-meson t-pole contribution to sigmaT, the transverse part of cross sectio

We suggest a description of the beam asymmetry in p (p) over bar and Lambda(Lambda) over bar photoproduction off the proton (gamma) over bar + p -> p (p) over bar + p and (gamma) over bar + p -> Lambda(Lambda) over bar + P , which takes into account
