Use of event-level neutrino telescope data in global fits for theories of new physics

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

We present a fast likelihood method for including event-level neutrino telescope data in parameter explorations of theories for new physics, and announce its public release as part of DarkSUSY 5.0.6. Our construction includes both angular and spectral info ...

Matter and antimatter in the universe

Marco Drewes, Laurent Canetti

We review observational evidence for a matter-antimatter asymmetry in the early universe, which leads to the remnant matter density we observe today. We also discuss bounds on the presence of antimatter in the present-day universe, including the possibilit ...

Search for GeV-Scale Sterile Neutrinos Responsible for Active Neutrino Oscillations and Baryon Asymmetry of the Universe

Standard Model fails to explain neutrino oscillations, dark matter, and baryon asymmetry of the Universe. All these problems can be solved with three sterile neutrinos added to SM. Quite remarkably, if sterile neutrino masses are well below the electroweak ...

Search for dark matter from the Galactic halo with the IceCube Neutrino Telescope

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

Self-annihilating or decaying dark matter in the Galactic halo might produce high energy neutrinos detectable with neutrino telescopes. We have conducted a search for such a signal using 276 days of data from the IceCube 22-string configuration detector ac ...

Review of Particle Physics

This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summa ...

The role of sterile neutrinos in cosmology and astrophysics

Alexey Boyarsky, Oleg Ruchayskiy

We present a comprehensive overview of an extension of the Standard Model that contains three right-handed (sterile) neutrinos with masses below the electroweak scale [the Neutrino Minimal Standard Model (vMSM)]. We consider the history of the Universe fro ...

Model independent constraints on mass-varying neutrino scenarios

Julien Lesgourgues

Models of dark energy in which neutrinos interact with the scalar field supposed to be responsible for the acceleration of the Universe usually imply a variation of the neutrino masses on cosmological time scales. In this work we propose a parametrization ...

Review of Particle Physics

Olivier Schneider, Pierre Vogel, Greig Alan Cowan, Jian Liu

This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2778 new measurements from 645 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summa ...

Sterile neutrino dark matter as a consequence of nuMSM-induced lepton asymmetry

It has been pointed out by one of the authors (Shaposhnikov 2008Preprint0804.4542) that in the νMSM (Standard Model extended with three right-handed neutrinos with masses smaller than the electroweak scale), there is a corner in the parameter space where C ...

How to find neutral leptons of the nuMSM?

An extension of the Standard Model by three singlet fermions with masses smaller than the electroweak scale allows to explain simultaneously neutrino oscillations, dark matter and baryon asymmetry of the Universe. We discuss the properties of neutral lepto ...
