Sterile neutrinos as dark matter

I describe the sterile neutrino dark matter candidate and discuss how it may fit into the overall picture of physics beyond the Standard Model. ...

Search for B+ -> mu(+)nu(mu) and B+ -> mu N+ with inclusive tagging

Olivier Schneider, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Donghyun Kim

We report the result for a search for the leptonic decay of B+ -> mu(+)nu mu using the full Belle dataset of 711 fb(-1) of integrated luminosity at the gamma(4S) resonance. In the Standard Model leptonic B-meson decays are helicity and Cabibbo-Kobayashi-Ma ...

A White Paper on keV sterile neutrino Dark Matter

Antoine Pierre Emmanuel Alexis Merle, Alexey Boyarsky, Laurent Gastaldo, Jonathan Leon Wolf, Julien Lesgourgues, Oleg Ruchayskiy, Marco Drewes, Igor Tkachev, Jan Hamann

We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved - cosmology, astrophysics, nuclear, and particle physics - in each case viewed from both theoretical and experimental/o ...

Satellite galaxies in semi-analytic models of galaxy formation with sterile neutrino dark matter

Alexey Boyarsky, Oleg Ruchayskiy

The sterile neutrino is a viable darkmatter candidate that can be produced in the early Universe via non-equilibrium processes, and would therefore possess a highly non-thermal spectrum of primordial velocities. In this paper we analyse the process of stru ...

Constraint on neutrino masses from SDSS-III/BOSS Ly alpha forest and other cosmological probes

Julien Lesgourgues, Arnaud Borde

We present constraints on the parameters of the ACDM cosmological model in the presence of massive neutrinos, using the one-dimensional Ly alpha forest power spectrum obtained with the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky ...

Cosmology with self-interacting sterile neutrinos and dark matter: A pseudoscalar model

Short baseline neutrino oscillation experiments have shown hints of the existence of additional sterile neutrinos in the eV mass range. Such sterile neutrinos are incompatible with cosmology because they suppress structure formation unless they can be prev ...

Search for neutrino-induced particle showers with IceCube-40

Matthias Wolf, Shirit Cohen, Sofia Vallecorsa, Mark Tobin, Mathieu Ribordy, Xiaoxia Bai

We report on the search for neutrino-induced particle showers, so-called cascades, in the IceCube-40 detector. The data for this search were collected between April 2008 and May 2009 when the first 40 IceCube strings were deployed and operational. Three co ...

Can active-sterile neutrino oscillations lead to chaotic behavior of the cosmological lepton asymmetry?

While the cosmic baryon asymmetry has been measured at high accuracy to be 6.1 x 10(-10), a corresponding lepton asymmetry could be as large as 10(-2) if it hides in the neutrino sector. It has been known for some time that such an asymmetry could be gener ...

Dark matter, baryogenesis and neutrino oscillations from right-handed neutrinos

Marco Drewes, Laurent Canetti, Tibor Frossard

We show that, leaving aside accelerated cosmic expansion, all experimental data in high energy physics that are commonly agreed to require physics beyond the Standard Model can be explained when completing the model by three right-handed neutrinos that can ...

Sterile Neutrinos as the Origin of Dark and Baryonic Matter

Marco Drewes, Laurent Canetti

We demonstrate for the first time that three sterile neutrinos alone can simultaneously explain neutrino oscillations, the observed dark matter, and the baryon asymmetry of the Universe without new physics above the Fermi scale. The key new point of our an ...
