Magnetic diffusion effects on the Ultra-High Energy Cosmic Ray spectrum and composition
(Iop Publishing, 2013-09)
We discuss the effects of diffusion of high energy cosmic rays in turbulent extra-galactic magnetic fields. We find an approximate expression for the low energy suppression of the spectrum of the different mass components ...
The Gamow-state description of the decay energy spectrum of neutron-unbound 25O
(Elsevier Science, 2018-02)
We show the feasibility of calculating the decay energy spectrum of neutron emitting nuclei within the Gamow-state description of resonances by obtaining the decay energy spectrum of 25O. We model this nucleus as a valence ...
On the energy of the protons producing the very high-energy astrophysical neutrinos
(IOP Publishing, 2021-03)
We study the distribution of the energy of the protons that can produce an astrophysical neutrino with a given observed energy, in the TeV-PeV range, both through pp or pγ interactions. Due to the increasing multiplicity ...
Decay of Batchelor and Saffman rotating turbulence
(American Physical Society, 2012-12)
The decay rate of isotropic and homogeneous turbulence is known to be affected by the large-scale spectrum of the initial perturbations, associated with at least two canonical self-preserving solutions of the von Kármán-Howarth ...
Anisotropy and nonuniversality in scaling laws of the large-scale energy spectrum in rotating turbulence
(American Physical Society, 2012-09)
Rapidly rotating turbulent flow is characterized by the emergence of columnar structures that are representative of quasi-two-dimensional behavior of the flow. It is known that when energy is injected into the fluid at an ...
Progress in high-energy cosmic ray physics
(Elsevier Science, 2018-01)
We review some of the recent progress in our knowledge about high-energy cosmic rays, with an emphasis on the interpretation of the different observational results. We discuss the effects that are relevant to shape the ...
The shape of the extragalactic cosmic ray spectrum from galaxy clusters
(IOP Publishing, 2016-08-05)
We study the diffusive escape of cosmic rays from a central source inside a galaxy cluster to obtain the suppression in the outgoing flux appearing when the confinement times get comparable or larger than the age of the ...
Transverse-momentum resummation and the spectrum of the Higgs boson at the LHC
(Elsevier Science, 2006-12)
We consider the transverse-momentum (qT) distribution of generic high-mass systems (lepton pairs, vector bosons, Higgs particles,...) produced in hadron collisions. At small qT, we concentrate on the all-order resummation ...
Dual structure in the charge excitation spectrum of electron-doped cuprates
(American Physical Society, 2017-12)
Motivated by the recent resonant x-ray scattering (RXS) and resonant inelastic x-ray scattering (RIXS) experiments for electron-doped cuprates, we study the charge excitation spectrum in a layered t-J model with the ...
