Perturbative fragmentation
B. Z. Kopeliovich, H. -J. Pirner, I. K. Potashnikova +2
The Berger model of perturbative fragmentation of quarks to pions is improved by providing an absolute normalization and keeping all terms in a (1-z) expansion, which makes the cal…
Azimuthal Asymmetry of Prompt Photons in Nuclear Collisions
B. Z. Kopeliovich, A. H. Rezaeian, Ivan Schmidt
The azimuthal elliptic asymmetry v2 observed in heavy ion collisions, is usually associated with properties of the medium created in the final state. We compute the azimuthal asymm…
Remarks on confinement driven by axion-like particles in Yang-Mills theories
Patricio Gaete, Euro Spallucci
Features of screening and confinement are studied for a non-Abelian gauge theory with a mixture of pseudoscalar and scalar coupling, in the case where a constant chromo-electric, o…
On scale symmetry breaking and confinement in D=3 models
Patricio Gaete, José A. Helaÿel-Neto
Within the framework of the gauge-invariant, but path-dependent, variables formalism, we study the connection between scale symmetry breaking and confinement in three-dimensional g…
Transport properties of graphene nanoribbon heterostructures
L. Rosales, P. Orellana, Z. Barticevic +1
We study the electronic and transport properties of heterostructures formed by armchair graphene nanoribbons with intersections of finite length. We describe the system by a tight-…
Transport modulation of graphene nanoribbons with side-attached organic molecules
L. Rosales, M. Pacheco, Z. Barticevic +2
In this work we address the effects on the conductance of graphene nanoribbons (GNRs) at which organic molecules are side-attached on the ribbon ends. For simplicity, only armchair…
Heavy Ion Collisions at the LHC - Last Call for Predictions
S. Abreu, S. V. Akkelin, J. Alam +164
This writeup is a compilation of the predictions for the forthcoming Heavy Ion Program at the Large Hadron Collider, as presented at the CERN Theory Institute 'Heavy Ion Collisions…
Vortex core size in interacting cylindrical nanodot arrays
D. Altbir, J. Escrig, P. Landeros +2
The effect of dipolar interactions among cylindrical nanodots, with a vortex-core magnetic configuration, is analyzed by means of analytical calculations. The cylinders are placed…
Azimuthal anisotropy of direct photons
B. Z. Kopeliovich, H. J. Pirner, A. H. Rezaeian +1
The electromagnetic bremsstrahlung produced by a quark interacting with nucleons or nuclei is azimuthally asymmetric. In the light-cone dipole approach this effect is related to th…
Angular dependence of coercivity in magnetic nanotubes
J. Escrig, M. Daub, P. Landeros +2
The nucleation field for infinite magnetic nanotubes, in the case of a magnetic field applied parallel to the long axis of the tubes, is calculated as a function of their geometric…
Exponentially Modified QCD Coupling
Gorazd Cvetic, Cristian Valenzuela
We present a specific class of models for an infrared-finite analytic QCD coupling, such that at large space-like energy scales the coupling differs from the perturbative one by le…
Gluon self-interaction in the position space in Landau gauge
Gorazd Cvetic, Igor Kondrashuk
We propose a method to treat the three-gluon self-interaction vertex in the position space in D = 4 - 2e dimensions. As an example, we calculate a two-loop contribution to auxiliar…
Pion dominance in RPV SUSY induced neutrinoless double beta decay
Amand Faessler, Thomas Gutsche, Sergey Kovalenko +1
At the quark level there are basically two types of contributions of R-parity violating SUSY (RPV SUSY) to neutrinoless double beta decay: the short-range contribution involving on…
Evidences for two scales in hadrons
B. Z. Kopeliovich, I. K. Potashnikova, B. Povh +1
Some unusual features observed in hadronic collisions at high energies can be understood assuming that gluons in hadrons are located within small spots occupying only about 10% of…
Confinement from gluodynamics in curved space-time
Patricio Gaete, Euro Spallucci
We determine the static potential for a heavy quark-antiquark pair from gluodynamics in curved space-time. Our calculation is done within the framework of the gauge-invariant, path…
Direct photons at LHC
A. H. Rezaeian, B. Z. Kopeliovich, H. J. Pirner +1
The DGLAP improved color dipole approach provides a good description of data for inclusive direct photon spectra at the energies of RHIC and Tevatron. Within the same framework we…
Higgs Hadroproduction at Large Feynman x
Stanley J. Brodsky, Alfred S. Goldhaber, Boris Z. Kopeliovich +1
We propose a novel mechanism for the production of the Higgs boson in inclusive hadronic collisions, which utilizes the presence of heavy quarks in the proton wave function. In the…
Heavy-Quark Kinetics in the QGP at LHC
H. van Hees, V. Greco, R. Rapp
We present predictions for the nuclear modification factor and elliptic flow of D and B mesons, as well as of their decay electrons, in semicentral Pb-Pb collisions at the LHC. Hea…
Thermal Dileptons at LHC
H. van Hees, R. Rapp
We predict dilepton invariant-mass spectra for central 5.5 ATeV Pb-Pb collisions at LHC. Hadronic emission in the low-mass region is calculated using in-medium spectral functions o…
Properties of noncommutative axionic electrodynamics
Patricio Gaete, Iván Schmidt
Using the gauge-invariant but path-dependent variables formalism, we compute the static quantum potential for noncommutative axionic electrodynamics, and find a radically different…
Jet lag effect and leading hadron production
B. Z. Kopeliovich, H. -J. Pirner, I. K. Potashnikova +1
We propose a solution for the long standing puzzle of a too steeply falling fragmentation function for a quark fragmenting into a pion, calculated by Berger [1] in the Born approxi…
