Ultra-high energy extragalactic neutrinos interacting with ultra-light dark matter
(2012-11-01)
We show the results and discussions of the study of a possible suppression of the extragalactic neutrino flux during its propagation due to a nonstandard interaction with a candidate field to dark matter. In particular, ...

Total hadronic cross section and the elastic slope: An almost model-independent connection
(Elsevier Science BvAmsterdamHolanda, 2012)
Short-distance part of the interaction of D mesons and nucleons
(2008-12-01)
The short-distance part of the low energy interaction of D-mesons and nucleons is investigated in the context of a quark model. The quark model is based on Coulomb gauge QCD. The model contains a confining Coulomb potential ...

The KASCADE-Grande energy spectrum of cosmic rays and the role of hadronic interaction models
(ElsevierAmsterdam, 2014-05)
Previous results obtained by KASCADE-Grande using the QGSjetII-02 hadronic interaction model have shown that the energy spectrum of cosmic rays between '10 POT. 16' eV and '10 POT. 18' eV exhibits a significant hardening ...
Asymptotic Scenarios for the Proton's Central Opacity: An Empirical Study
(Amer Inst Physics, 2015-01-01)
We present a model-independent analysis of the experimental data on the ratio X between the elastic and total cross-sections from pp and p (p) over bar scattering in the c.m. energy interval 5 GeV - 8 TeV. Using a novel ...
Detailed parametrization of neutrino and gamma-ray energy spectra from high energy proton-proton interactions
(American Physical Society, 2016-02)
Gamma rays and neutrinos are produced as a result of proton-proton interactions that occur in different astrophysical contexts. The detection of these two types of messengers is of great importance for the study of different ...
