Energy transfer between electrons and ions in collision cascades in solids
Abstract This paper attempts an overview of the mechanisms, rates, and characteristics of the several processes by which electronic and ionic energy exchange can occur. This energy exchange raises questions about widely accepted assumptions, and the ...

The chiral critical point in 3-flavour QCD
Abstract We determine the second order endpoint of the line of first order phase transitions, which occur in the light quark mass regime of 3-flavour QCD at finite temperature, and analyze universal properties of this chiral critical point. A...

Photon propagation in space–time with a compactified spatial dimension
Abstract The one-loop effects of vacuum polarization induced by untwisted fermions in QED in a nonsimply connected space–time with topology S 1×R 3 are investigated. It is found that photon propagation in...

Hard photon and neutral pion production in cold nuclear matter
Abstract The production of hard photons and neutral pions in 190 MeV proton induced reactions on C, Ca, Ni, and W targets has been for the first time concurrently studied. Angular distributions and energy spectra up to the kinematical limit are...

Randall–Sundrum scenario at nonzero temperature
Abstract The effect of temperature is investigated in the Randall–Sundrum brane-world scenario. It is shown that for a spacetime ansatz motivated by similarity with AdS/CFT correspondence several features of the model, such as its Z ...

b-quark mediated neutrinoless μ−–e− conversion in presence of R-parity violation
Abstract We found that in supersymmetric models with R-parity non-conservation ( R / p SUSY) the...

Chiral anomalies in noncommutative YM theories
Abstract Using cohomological methods we discuss several issues related to chiral anomalies in noncommutative U(N) YM theories in any even dimension. We show that for each dimension there is only one solution of the WZ consistency condition and that...

Center vortices on SU(2) lattices
Abstract We show that gauge invariant definitions of thin, thick and hybrid center vortices, defined by Kovacs and Tomboulis on SO(3)×Z(2) configurations, can also be defined in SU(2). We make this connection using the freedom of choosing a...

Criterion for Blind Signals Separation Based on Correlation Function
Abstract Blind separation of source signals usually relies either on the condition of statistically independence or involving their higher-order cumulants. The model of two channels signal separation is considered. A criterion based on correlation...

Nonlinear gravitational waves and their polarization
Abstract Vacuum gravitational fields invariant for a non-Abelian Lie algebra generated by two Killing fields whose commutator is light-like are analyzed. It is shown that they represent non-linear gravitational waves obeying to two non-linear...

Possible improvements on the mass of ντ using leptonic D±s decays
Abstract We show how a very accurate measurement of the branching ratios of the leptonic decay modes of the D ± S mesons can lead to an improvement in the mass...

The wobbling mode in 167Lu
Abstract High spin states in 167Lu were populated through the 123Sb(48Ca, xn) reaction at 203 MeV. Four, presumably triaxial, strongly deformed (TSD) bands have been found in this nucleus. Several transitions linking an...

Lorentz invariance relations among parton distributions revisited
Abstract We revisit the derivation of the so-called Lorentz invariance relations between parton distributions. In the most important cases these relations involve twist-3 and transverse momentum dependent parton distributions. It is shown that these ...

Extra gauge symmetry for extra supersymmetry
Abstract It is shown that the extra supersymmetry of tensionless superstring and super p-brane is accompanied by the presence of new bosonic gauge symmetries. It permits to use composed coordinates encoding all physical degrees of freedom of the...

Cluster interpretation of parity splitting in alternating parity bands
Abstract The parity splitting in actinides is described with a cluster model of oscillations in mass asymmetry coordinate. The spin dependence of the calculated parity splitting is in a good agreement with the experimental data. ...

On the recently proposed mimetic Dark Matter
Abstract Recently, an interesting gravitational model was proposed in order to mimic the effect of Dark Matter. Chamseddine and Mukhanov in the arXiv preprint 1308.5410 have separated the conformal mode of a physical metric in the form of a squared...

Effective macroscopic interfacial transport equations in strongly heterogeneous environments for general homogeneous free energies
Abstract We study phase field equations in perforated domains for arbitrary free energies. These equations have found numerous applications in a wide spectrum of both science and engineering problems with homogeneous environments. Here, we focus on...
