Reconciling resonant leptogenesis and baryogenesis via neutrino oscillations

Mikhail Chapochnikov, Inar Timiryasov, Juraj Klaric

Right-handed neutrinos offer an elegant solution to two well-established phenomena beyond the Standard Model (SM)-masses and oscillations of neutrinos, as well as the baryon asymmetry of the Universe. It is also a minimalistic solution, since it requires o ...

MeV-scale seesaw and leptogenesis

Marco Drewes, Michele Lucente, Valerie Fiona Domcke

We study the type-I seesaw model with three right-handed neutrinos and Majorana masses below the pion mass. In this mass range, the model parameter space is not only strongly constrained by the requirement to explain the light neutrino masses, but also by ...

Self-interacting neutrinos: Solution to Hubble tension versus experimental constraints

Emmanuel Stamou

Exotic self-interactions among the Standard Model neutrinos have been proposed as a potential reason behind the tension in the expansion rate, H-0, of the universe inferred from different observations. We constrain this proposal using electroweak precision ...

An allowed window for heavy neutral leptons below the kaon mass

Alexey Boyarsky, Oleg Ruchayskiy, Inar Timiryasov, Juraj Klaric, Kyrylo Bondarenko

The extension of the Standard Model with two gauge-singlet Majorana fermions can simultaneously explain two beyond-the-Standard-model phenomena: neutrino masses and oscillations, as well as the origin of the matter-antimatter asymmetry in the Universe. The ...

Feebly-Interacting Particles:FIPs 2020 Workshop Report

Martin Bauer, Alexey Boyarsky, Oleg Ruchayskiy, Lesya Shchutska, Marco Drewes

With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader particle and astrophysics community for exploring the physics of light and feebl ...

Probing sub-eV Dark Matter decays with PTOLEMY

Alexey Boyarsky, Kyrylo Bondarenko

When the Dark Matter mass is below the eV-scale, its cosmological occupation number exceeds the ones of photons from the cosmic microwave background as well as of relic neutrinos. If such Dark Matter decays to pairs of neutrinos, it implies that experiment ...

Euclid preparation: IX. EuclidEmulator2-power spectrum emulation with massive neutrinos and self-consistent dark energy perturbations

Georges Meylan, Fabio Finelli, Richard Massey, Gianluca Castignani, Yi Wang

We present a new, updated version of the EuclidEmulator (called EuclidEmulator2), a fast and accurate predictor for the nonlinear correction of the matter power spectrum. 2 per cent level accurate emulation is now supported in the eight-dimensional paramet ...

Test of lepton flavor universality and search for lepton flavor violation in B -> Kll decays

Olivier Schneider, Sun Hee Kim, Mingkui Wang, Chao Wang, Donghyun Kim, Lei Li, Yiming Li, Xiao Wang

We present measurements of the branching fractions for the decays B -> K mu(+)mu(-) and B -> Ke(+)e(-), and their ratio (R-K), using a data sample of 711 fb(-1) that contains 772 x 10(6) B (B) over bar events. The data were collected at the Gamma(4S) reson ...
