Design concepts for the Cherenkov Telescope Array CTA: An advanced facility for ground-based high-energy gamma-ray astronomy

Marcos Daniel Actis, +685 more
TL;DR: The ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes as mentioned in this paper, which is an international initiative to build the next generation instrument, with a factor of 5-10 improvement in sensitivity in the 100 GeV-10 TeV range and the extension to energies well below 100GeV and above 100 TeV.
Journal ArticleDOI

A Lower bound on the right-handed neutrino mass from leptogenesis

TL;DR: In the see-saw model, the baryon asymmetry of the Universe can be generated by the decay of the lightest right-handed neutrino, νR as discussed by the authors.
Journal ArticleDOI

A facility to search for hidden particles at the CERN SPS: the SHiP physics case.

Sergey Alekhin, +95 more
TL;DR: It is demonstrated that the SHiP experiment has a unique potential to discover new physics and can directly probe a number of solutions of beyond the standard model puzzles, such as neutrino masses, baryon asymmetry of the Universe, dark matter, and inflation.
Journal ArticleDOI

A facility to Search for Hidden Particles at the CERN SPS: the SHiP physics case

TL;DR: The SHiP (Search for Hidden Particles) experiment at CERN as discussed by the authors was designed to search for new physics in the largely unexplored domain of very weakly interacting particles with masses below the Fermi scale, inaccessible to the LHC experiments.
Journal ArticleDOI

Fermi LAT Search for Internal Bremsstrahlung Signatures from Dark Matter Annihilation

TL;DR: In this article, a new adaptive procedure was proposed to select optimal target regions that takes into account both standard and contracted dark matter profiles, with a significance of 3.1σ (4.3σ) for an internal bremsstrahlung-like signal that would correspond to a dark matter mass of ~150 GeV.
