The cos 2 phi asymmetry of Drell-Yan and J/psi production in unpolarized ppbar scattering

Vincenzo Barone, Zhun Lu, Bo-Qiang Ma

We investigate the cos 2 phi azimuthal asymmetry in Drell--Yan and J/psi production from unpolarized ppbar scattering at GSI-HESR energies. The contribution to this asymmetry arisi…

A detailed analysis of dipolar interactions and analytical approximations in arrays of magnetic nanowires

D. Laroze, J. Escrig, P. Landeros +3

The investigation of the role of interactions in magnetic wire arrays is complex and often subject to strong simplifications. In this paper we obtained analytical expressions for t…

Magnetic-field effects on transport in carbon nanotube junctions

L. Rosales, M. Pacheco, Z. Barticevic +2

Here we address a theoretical study on the behaviour of electronic states of heterojunctions and quantum dots based on carbon nanotubes under magnetic fields. Emphasis is put on th…

Photon-assisted transport in a carbon nanotube

P. A. Orellana, M. Pacheco

We investigate the quantum transport through a single-wall carbon nanotube connected to leads in the presence of an external radiation field. We analyze the conductance spectrum as…

Generalized Path Dependent Representations for Gauge Theories

Marat C. Reyes

A set of differential operators acting by continuous deformations on path dependent functionals of open and closed curves is introduced. Geometrically, these path operators are int…

Connection between the Sivers function and the anomalous magnetic moment

Zhun lu, Ivan Schmidt

The same light-front wave functions of the proton are involved in both the anomalous magnetic moment of the nucleon and the Sivers function. Using the diquark model, we derive a si…

Extended Black Box Theorem for Lepton Number and Flavor Violating processes

M. Hirsch, S. Kovalenko, I. Schmidt

We revisit the well known "Black Box" theorem establishing a fundamental relation between the amplitude of neutrinoless double beta decay and the effective Majorana neutrino mass.…

Time Evolution of Jets and Perturbative Color Neutralization

B. Z. Kopeliovich, J. Nemchik, Ivan Schmidt

In-medium production of leading hadrons in hard reactions, carrying the main fraction of the jet momentum, involves two stages: (i) the parton originated from the hard process prop…

Various versions of analytic QCD and skeleton-motivated evaluation of observables

Gorazd Cvetic, Cristian Valenzuela

We present skeleton-motivated evaluation of QCD observables. The approach can be applied in analytic versions of QCD in certain classes of renormalization schemes. We present two v…

Lepton flavor violation in muonium decay and muon colliders in models with heavy neutrinos

Gorazd Cvetic, Claudio O. Dib, Choong-Sun Kim +1

We study the lepton-flavor-violating reaction $μ^{+} e^{-} \to e^{+} e^{-}$ within two extensions of the standard model that include heavy neutrinos. The reaction is studied in the low ene…

Glue drops inside hadrons

B. Z. Kopeliovich, B. Povh, Ivan Schmidt

We present experimental evidences for the existence of a semi-hard scale in light hadrons. This includes the suppression of gluon radiation that is seen in high mass hadron diffrac…

Lorentz Violating Julia-Toulouse Mechanism

Patricio Gaete, Clovis Wotzasek

We propose a new Lorentz invariant violating extension for the pure photonic sector of the Standard Model due to the condensation of topological defects in the context of the Julia…

Confinement from constant field condensates

Patricio Gaete, Eduardo Guendelman, Euro Spallucci

For a $(2 + 1)$ -dimensional reformulated SU(2) Yang-Mills theory, we compute the interaction potential within the framework of the gauge-invariant but path-dependent variables formal…

Confinement from spontaneous breaking of scale symmetry

Patricio Gaete, Eduardo Guendelman

We show that one can obtain naturally the confinement of static charges from the spontaneous symmetry breaking of scale invariance in a gauge theory. At the classical level a confi…

Thermal Operator and Cutting Rules at Finite Temperature and Chemical Potential

F. T. Brandt, Ashok Das, Olivier Espinosa +2

In the context of scalar field theories, both real and complex, we derive the cutting description at finite temperature (with zero/finite chemical potential) from the cutting rules…

Implications of R-parity violating supersymmetry for atomic and hadronic EDMs

Amand Faessler, Thomas Gutsche, Sergey Kovalenko +1

We calculate the electric dipole moments (EDM) of the neutral Hg(199) atom, deuteron, nucleons and neutral hyperons Lambda, Sigma(0) and Xi(0) in the framework of a generic SUSY mo…
