Physical and mathematical evidences for a negative-rank tensor
Patricio Gaete, Clovis Wotzasek
We propose and study the properties of a new potential demanded by the self-consistency of the duality scheme in electromagnetic-like field theories of totally anti-symmetric tenso…
Confinement effects from interacting chromo-magnetic and axion fields
Patricio Gaete, Euro Spallucci
We study a non-Abelian gauge theory with a pseudo scalar coupling ϕε^{μναβ} F_{μν}^a F_{αβ}^a in the case where a constant chromo-electric, or chromo-magnetic, strength expectation…
Relation between Lepton Flavor Violating Processes
Sergey Kovalenko, Ivan Schmidt
We demonstrate the existence of model independent one-to-one correspondence relations between different lepton flavor violating processes (LFV). Applying the criterion of naturalne…
Quark and Gluon Sivers Functions
Ivan Schmidt
The physics of hadron single transverse spin asymmetries is discussed. Possible measurements of both the quark and gluon Sivers functions are proposed.
Generalized Distribution Amplitudes at the pole
Zhun Lu, Ivan Schmidt
We investigate the exclusive two-pion production at the -pole through the process . In the kinematical region where the invariant mass of the two pions is m…
Large critical exponents for some second order uniformly elliptic operators
Maria J. Esteban, Patricio Felmer, Alexander Quaas
In this paper we investigate the critical exponents of two families of Pucci's extremal operators. The notion of critical exponent that we have chosen for these fully nonlinear ope…
Double Higgs Production and Quadratic Divergence Cancellation in Little Higgs Models with T Parity
Claudio O. Dib, Rogerio Rosenfeld, Alfonso Zerwekh
We analyze double Higgs boson production at the Large Hadron Collider in the context of Little Higgs models. In double Higgs production, the diagrams involved are directly related…
Strong CP violation and the neutron electric dipole form factor
J. Kuckei, Claudio Dib, Amand Faessler +4
We calculate the neutron electric dipole form factor induced by the CP violating theta-term of QCD, within a perturbative chiral quark model which includes pion and kaon clouds. On…
Double Higgs Production at the LHC as a robust test of Little Higgs models
Claudio O. Dib, Rogerio ROsenfeld, Alfonso Zerwekh
We analyze double Higgs boson production at the LHC in the context of Little Higgs models. In double Higgs production, the diagrams involved are directly related to those that caus…
Large Rapidity Gap Processes in Proton-Nucleus Collisions
B. Z. Kopeliovich, I. K. Potashnikova, Ivan Schmidt
The cross sections for a variety of channels of proton-nucleus interaction associated with large gaps in rapidity are calculated within the Glauber-Gribov theory. We found inelasti…
A modification of minimal analytic QCD at low energies
G. Cvetic, C. Valenzuela, I. Schmidt
We present an approach which allows for modifications of the (minimal) analytic QCD model of Shirkov, Solovtsov et al. The discontinuity function of the (minimal) analytic QCD coup…
Thermal Operator Representation of Finite Temperature Graphs
Fernando T. Brandt, Ashok Das, Olivier Espinosa +2
Using the mixed space representation (t,p) in the context of scalar field theories, we prove in a simple manner that the Feynman graphs at finite temperature are related to the cor…
Recursive method to obtain the parametric representation of a generic Feynman diagram
Ivan Gonzalez, Ivan Schmidt
A recursive algebraic method which allows to obtain the Feynman or Schwinger parametric representation of a generic L-loops and (E+1) external lines diagram, in a scalar $ϕ^{3}\opl…
Coulomb interaction effects on the electronic structure of radial polarized excitons in nanorings
Z. Barticevic, M. Pacheco, J. Simonin +1
The electronic structure of radially polarized excitons in structured nanorings is analyzed, with emphasis in the ground-state properties and their dependence under applied magneti…
Shadowing and Antishadowing in Neutrino Deep Inelastic Scattering
Ivan Schmidt
The coherence of multiscattering quark nuclear processes leads to shadowing and antishadowing of the electromagnetic nuclear structure functions in agreement with measurements. Thi…
Scalar meson mediated nuclear mu-e conversion
Amand Faessler, Th. Gutsche, Sergey Kovalenko +2
We study the nuclear mu-e conversion in the general framework of the effective Lagrangian approach without referring to any specific realization of the physics beyond the standard…
Neutrino emission rates in highly magnetized neutron stars revisited
Mario Riquelme, Andreas Reisenegger, Olivier Espinosa +1
Magnetars are a subclass of neutron stars whose intense soft-gamma-ray bursts and quiescent X-ray emission are believed to be powered by the decay of a strong internal magnetic fie…
Muonium-antimuonium conversion in models with heavy neutrinos
Gorazd Cvetic, Claudio O. Dib, C. S. Kim +1
We study muonium-antimuonium conversion and mu+ e- to mu- e+ scattering within two different lepton-flavor-violating models with heavy neutrinos: model I is a typical seesaw that v…
Transverse single spin asymmetries in photon production
Ivan Schmidt, Jacques Soffer, Jian-Jun Yang
Transverse single-spin asymmetries (SSA) in inclusive reactions are now considered to be directly related to the transverse momentum of the fundamental partons involv…
Duality and confinement in D=3 models driven by condensation of topological defects
Patricio Gaete, Clovis Wotzasek
We study the interplay of duality and confinement in certain three-dimensional models induced by the condensation of topological defects. To this end we check for the confinement p…
Spontaneous CP Symmetry Breaking at the Electroweak Scale
Cristian Valenzuela
We present a top-condensation model in which the CP symmetry is spontaneously broken at the electroweak scale due to the condensation of two composite Higgs doublets. In particular…
Persistent current magnification in a double quantum-ring system
P. A. Orellana, M. Pacheco
The electronic transport in a system of two quantum rings side-coupled to a quantum wire is studied via a single-band tunneling tight-binding Hamiltonian. We derived analytical exp…
