DVCS via color dipoles: Nonperturbative effects
B. Z. Kopeliovich, Ivan Schmidt, M. Siddikov
We study the DVCS amplitude within the color dipole approach. The light-cone wave function of a real photon is evaluated in the instanton vacuum model. Our parameter free calculati…
Search for Tau Flavour Violation at the LHC
E. Carquin, J. Ellis, M. E. Gomez +2
We explore the prospects for searches at the LHC for sparticle decays that violate lepton number, in the light of neutrino oscillation data and the seesaw model for neutrino ma…
Transverse Momentum Broadening in Semi-inclusive DIS on Nuclei
S. Domdey, D. Grunewald, B. Z. Kopeliovich +1
Using a three stage model of hadron formation we calculate the change of the transverse momentum distribution of hadrons produced in semi-inclusive deep inelastic scattering (SIDIS…
Modular application of an Integration by Fractional Expansion (IBFE) method to multiloop Feynman diagrams
Ivan Gonzalez, Ivan Schmidt
We present an alternative technique for evaluating multiloop Feynman diagrams, using the integration by fractional expansion method. Here we consider generic diagrams that contain…
Metastable states influence on the magnetic behavior of the triangular lattice: Application to the spin-chain compound Ca3Co2O6
R. Soto, G. Martínez, M. N. Baibich +2
It is known that the spin-chain compound Ca3Co2O6 exhibits very interesting plateaus in the magnetization as a function of the magnetic field at low temperatures. The origin of the…
Unitarity bound for gluon shadowing
B. Z. Kopeliovich, E. Levin, I. K. Potashnikova +1
Although at small Bjorken x gluons originated from different nucleons in a nucleus overlap in the longitudinal direction, most of them are still well separated in the transverse pl…
First measurement of direct photoproduction on the proton
CLAS Collaboration, M. Battaglieri, R. De Vita +1
We report on the results of the first measurement of exclusive meson photoproduction on protons for GeV and GeV. Data were collected w…
Hadrons in AdS / QCD correspondence
Alfredo Vega, Ivan Schmidt
We present an holographical soft wall model which is able to reproduce not only Regge spectra for hadrons with arbitrary integer spin, but also with spin 1/2 and 3/2, and with an a…
Glauber - Gribov approach for DIS on nuclei in N=4 SYM
E. Levin, J. Miller, B. Z. Kopeliovich +1
In this paper the Glauber-Gribov approach for deep-inelastic scattering (DIS) with nuclei is developed in N=4 SYM. It is shown that the amplitude displays the same general properti…
Applied High Energy QCD
B. Z. Kopeliovich, A. H. Rezaeian
These lectures stress the theoretical elements that underlie a wide range of phenomenological studies of high-energy QCD, which include both soft and hard processes. After a brief…
A Precise Measurement of the Neutron Magnetic Form Factor GMn in the Few-GeV2 Region
J. Lachniet, A. Afanasev, H. Arenhövel +5
The neutron elastic magnetic form factor GMn has been extracted from quasielastic electron scattering data on deuterium with the CEBAF Large Acceptance Spectrometer (CLAS) at Jeffe…
Cronin effect for protons and pions in pA collisions
A. H. Rezaeian, Zhun Lu
Pions and protons production cross-sections are analyzed in proton-proton and proton-nucleus collisions at the RHIC energy at midrapidity. We employ the pQCD factorization scheme s…
Confining potential from interacting magnetic and torsion fields
Patricio Gaete, José A. Helaÿel-Neto
Adopting the gauge-invariant but path-dependent variables formalism, we study the coupling of torsion fields with photons in the presence of an external background electromagnetic.…
Quantum-mechanical description of in-medium fragmentation
B. Z. Kopeliovich, H. -J. Pirner, I. K. Potashnikova +3
We present a quantum-mechanical description of quark-hadron fragmentation in a nuclear environment. It employs the path-integral formulation of quantum mechanics, which takes care…
Long-term operation of a multi-channel cosmic muon system based on scintillation counters with MRS APD light readout
A. Akindinov, V. Golovin, E. Grigoriev +7
A Cosmic Ray Test Facility (CRTF) is the first large-scale implementation of a scintillation triggering system based on a new scintillation technique known as START. In START, the…
Electroproduction of p π^{+} π^{-} off protons at 0.2<Q^{2}<0.6 GeV^{2} and 1.3<W<1.57 GeV with CLAS
G. V. Fedotov, V. I. Mokeev, V. D. Burkert +5
This paper reports on the most comprehensive data set obtained on differential and fully integrated cross sections for the process . The data were collec…
Azimuthal Asymmetry of pions in pp and pA collisions
B. Z. Kopeliovich, A. H. Rezaeian, Ivan Schmidt
We investigate the azimuthal asymmetry v2 of produced pions in pp and pA collisions at both RHIC and SPS energies. In our approach, based on the pQCD parton model and the light-con…
Measurement of unpolarized semi-inclusive pi+ electroproduction off the proton

Semi-inclusive pi+ electroproduction on protons has been measured with the CLAS detector at Jefferson Lab. The measurement was performed on a liquid-hydrogen target using a 5.75 Ge…
Oscillations of Dirac and Majorana neutrinos in matter and a magnetic field
Maxim Dvornikov, Jukka Maalampi
We study the evolution of massive mixed Dirac and Majorana neutrinos in matter under the influence of a transversal magnetic field. The analysis is based on relativistic quantum me…
