Parameter space of baryogenesis in the nu MSM

Inar Timiryasov, Shintaro Eijima

The Standard Model accompanied with two right-handed neutrinos with masses below the weak scale can explain the observed baryon asymmetry of the Universe. Moreover, this model is at least partially testable in the forthcoming experiments such as NA62, SHiP ...

Baryogenesis in the vMSM: recent developments

Extension of the Standard Model with two right-handed neutrinos provides an economic and testable explanation of the origin of the baryon asymmetry of the Universe. We review recent progress in understanding dynamics of the asymmetry generation. We also pr ...

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 ...

Neutrinoless double beta decay and low scale leptogenesis

Marco Drewes, Shintaro Eijima

The extension of the Standard Model by right handed neutrinos with masses in the GeV range can simultaneously explain the observed neutrino masses via the seesaw mechanism and the baryon asymmetry of the universe via leptogenesis. It has previously been cl ...

Lepton universality in the nu MSM

Shintaro Eijima

We consider the nu MSM which is an extension of the Standard Model by three right-handed neutrinos with masses below the electroweak scale, in which the origins of neutrino masses, dark matter, and baryon asymmetry of the universe are simultaneously explai ...

Hypermagnetic fields and baryon asymmetry from pseudoscalar inflation

Eray Sabancilar

We show that maximally helical hypermagnetic fields produced during pseudoscalar inflation can generate the observed baryon asymmetry of the Universe via the B + L anomaly in the Standard Model. We find that most of the parameter space of pseudoscalar infl ...

Asymmetric Particle Behavior during Size Segregation

Christophe Ancey, Kasper van der Vaart

We have performed oscillatory shear experiments on a bidisperse granular mixture in combination with refractive index matched scanning in order to resolve particle motion in three-dimensions during size-segregation. We find that small particles segregate f ...

Leading effects beyond the standard model

Francesco Riva

Using the predictive power of the effective field theory approach, we present a physical parametrization of the leading effects beyond the standard model (BSM), which gives us at present the best way to constrain heavy new physics at low energies. We show ...

Inflation, leptogenesis, and Yukawa quasiunification within a supersymmetric left-right model

Roberta Armillis

A simple extension of the minimal left-right symmetric supersymmetric grand unified theory model is constructed by adding two pairs of superfields. This naturally violates the partial Yukawa unification predicted by the minimal model. After including super ...

Quantum dimer model for the spin-1/2 kagome Z(2) spin liquid

Frédéric Mila, Ioannis Rousochatzakis

We revisit the description of the low-energy singlet sector of the spin-1/2 Heisenberg antiferromagnet on kagome in terms of an effective quantum dimer model. With the help of exact diagonalizations of appropriate finite-size clusters, we show that the emb ...
