Nucleon resonances in AdS/QCD
Thomas Gutsche, Valery E. Lyubovitskij, Ivan Schmidt +1
We describe the electroproduction of the N(1440) Roper resonance in soft-wall AdS/QCD. The Roper resonance is identified as the first radially excited state of the nucleon, where h…
Chiral Symmetry Breaking and Meson Wave Functions in Soft-Wall AdS/QCD
Thomas Gutsche, Valery E. Lyubovitskij, Ivan Schmidt +1
We consider mesons composed of light and heavy quarks and discuss the construction of the corresponding meson wave functions in soft-wall AdS/QCD. We specifically take care that co…
Phenomenological Constraints to Dimensionality of the Spacetime with Torsion
Oscar Castillo-Felisola, Cristobal Corral, Ivan Schmidt +1
Using the recent limits established by ATLAS to the contact four-fermion interaction, bounds on the size of the extra dimensions of space-time have been found, by assuming that the…
J/Psi production off nuclei: a detour from SPS to LHC
B. Z. Kopeliovich, I. K. Potashnikova, Ivan Schmidt
We present a collection of selected phenomena observed in J/Psi production from proton-nucleus and heavy ion collisions at energies, ranging between the SPS and LHC. The emphasis i…
Flavor structure of generalized parton distributions from neutrino experiments
B. Z. Kopeliovich, Ivan Schmidt, M. Siddikov
The analysis of deeply virtual meson production is extended to neutrino-production of the pseudo-Goldstone mesons (pions, kaons, eta-mesons) on nucleons, with the flavor content of…
Incurable Adler relation for soft neutrino interactions
B. Z. Kopeliovich, I. K. Potashnikova, Ivan Schmidt +1
The Adler relation (AR), which bridges soft interactions of neutrinos and pions, might look as a manifestation of pion dominance. However neutrino cannot fluctuate to a pion becaus…
