WIMP and FIMP dark matter in singlet-triplet fermionic model

Journal of High Energy Physics, 2022
We present an extension of the SM involving three triplet fermions, one triplet scalar and one singlet fermion, which can explain both neutrino masses and dark matter.

Anomaly-free dark matter models [PDF]

Physical Review D, 2019
We investigate the predictions of anomaly-free dark matter models for direct and indirect detection experiments. We focus on gauge theories where the existence of a fermionic dark matter candidate is predicted by anomaly cancellation, its mass is defined by the new symmetry breaking scale, and its stability is guaranteed by a remnant symmetry after the

Vector portals at future lepton colliders

Journal of High Energy Physics
We assess the sensitivity of future lepton colliders to weakly coupled vector dark portals (aka “Z ′ bosons”) with masses ranging from tens of GeV to a few TeV. Our analysis focuses on dark photons and L μ – L τ gauge bosons. We consider both visible and

The pyruvate generator is a common phenomenon in mitochondria from different rat and mouse brain regions

FEBS Letters, EarlyView.
The pyruvate generator, which causes activation of respiration by extra‐mitochondrial Ca2+, is also present and functional in rat brainstem mitochondria, as it is in other brain regions. This finding is confirmed by experiments with a fully reconstituted malate–aspartate shuttle (MAS).

Dark matter in multi-singlet extensions of the Standard Model

Journal of High Energy Physics
We study the simplest extensions of the Standard Model (SM) that provide Dark Matter (DM) candidates, built with the addition of real singlets and new Z 2 $$ {\mathcal{Z}}_2 $$ symmetries.

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

FEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells
