Deviations of exact neutrino textures using radiative neutrino masses
D. Wegman
The Weinberg operator allows for the construction of radiative Majorana neutrino masses. In this letter, it will be shown that it is possible to construct a one-loop diagram that w…
Probing decaying heavy dark matter with the 4-year IceCube HESE data
Atri Bhattacharya, Arman Esmaili, Sergio Palomares-Ruiz +1
After the first four years of data taking, the IceCube neutrino telescope has observed 54 high-energy starting events (HESE) with deposited energies between 20 TeV and 2 PeV. The b…
Enhanced neutrino emissivities in pseudoscalar-mediated Dark Matter annihilation in Neutron Stars
M. Cermeño, M. A. Pérez-García, R. A. Lineros
We calculate neutrino emissivities from self-annihilating dark matter () in the dense and hot stellar interior of a (proto)neutron star. Using a model where dark matter interact…
Stability of pentaquarks with a two- plus three-body chromoelectric interaction
Fl. Stancu
We study the stability of pentaquarks within a schematic model based on SU(3) color symmetry, by taking into account algebraic arguments leading to a chromoelectric interaction con…
Radiative Two-Loop Neutrino Masses with Dark Matter
C. Simoes, D. Wegman
Using the Weinberg operator, we present a full collection of genuine two-loop models for neutrino mass generation, which contain a dark matter particle as one of the internal messe…
Parton correlations in same-sign pair production via double parton scattering at the LHC
Federico Alberto Ceccopieri, Matteo Rinaldi, Sergio Scopetta
Same-sign boson pairs production is a promising channel to look for signatures of double parton interactions at the LHC. The corresponding cross section has been calculated by…
