1. Particle physics origin of the 5 MeV bump in the reactor antineutrino spectrum? / Berryman, Jeffrey M. ; Brdar, Vedran ; Huber, Patrick
One of the most puzzling questions in neutrino physics is the origin of the excess at 5 MeV in the reactor antineutrino spectrum. [...]

2. Conformal realization of the neutrino option / Brdar, Vedran ; Emonds, Yannick ; Helmboldt, Alexander J. ; Lindner, Manfred
It was recently proposed that the electroweak hierarchy problem is absent if the generation of the Higgs potential stems exclusively from quantum effects of heavy right-handed neutrinos which can also generate active neutrino masses via the type-I seesaw mechanism. [...]

3. Production of keV sterile neutrinos in supernovae: New constraints and gamma-ray observables / Argüelles, Carlos A. ; Brdar, Vedran ; Kopp, Joachim
We study the production of sterile neutrinos in supernovae, focusing in particular on the keV-MeV mass range, which is the most interesting range if sterile neutrinos are to account for the dark matter in the Universe. [...]

4. Low scale left-right symmetry and naturally small neutrino mass / Brdar, Vedran ; Smirnov, Alexei
We consider the low scale (10-100 TeV) left-right symmetric model with “naturally” small neutrino masses generated through the inverse seesaw mechanism. [...]

5. Producing a new fermion in coherent elastic neutrino-nucleus scattering: from neutrino mass to dark matter / Brdar, Vedran ; Rodejohann, Werner ; Xu, Xun-Jie
We consider the production of a new MeV-scale fermion in coherent elastic neutrino-nucleus scattering. [...]

6. The new ν MSM ( νν MSM): radiative neutrino masses, keV-scale dark matter and viable leptogenesis with sub-TeV new physics / Baumholzer, Sven ; Brdar, Vedran ; Schwaller, Pedro
We study the scenario in which the Standard model is augmented by three generations of right-handed neutrinos and a scalar doublet. [...]

7. X-Ray Lines from Dark Matter Annihilation at the keV Scale / Brdar, Vedran ; Kopp, Joachim ; Liu, Jia ; Wang, Xiao-Ping
In 2014, several groups reported hints for a yet unidentified line in astrophysical x-ray signals from galaxies and galaxy clusters at an energy of 3.5 keV. [...]

8. Fuzzy dark matter and nonstandard neutrino interactions / Brdar, Vedran ; Kopp, Joachim ; Liu, Jia ; Prass, Pascal ; et al
We discuss novel ways in which neutrino oscillation experiments can probe dark matter. [...]

9. Radiative neutrino mass with scotogenic scalar triplet / Brdar, Vedran ; Picek, Ivica ; Radovčić, Branimir
We present a radiative one-loop neutrino mass model with hypercharge zero scalar triplet in conjunction with another charged singlet scalar and an additional vectorlike lepton doublet. [...]
