A thermal neutrino interaction rate at NLO
Nuclear Physics B, 2020 The interaction rate of an ultrarelativistic active neutrino at a temperature below the electroweak crossover plays a role in leptogenesis scenarios based on oscillations between active neutrinos and GeV-scale sterile neutrinos.

Right-handed neutrino dark matter under the B − L gauge interaction [PDF]
, 2016 A bstractWe study the right-handed neutrino (RHN) dark matter candidate in the minimal U(1)B−L gauge extension of the standard model. The U(1)B−L gauge symmetry offers three RHNs which can address the origin of the neutrino mass, the relic dark matter ...

AMS-02, Strongly Self-Interacting Dark Matter, and QUD [PDF]
, 2014 The latest AMS-02 electron/positron precision data add to the spectrum knee as direct cosmic ray evidence for an electroweak scale strong interaction. In addition, there is significant evidence for a strong self-interaction of dark matter.

Detecting Technibaryon Dark Matter
, 1993 The technibaryon constitutes a possible dark matter candidate. Such a particle with electroweak quantum numbers is already nearly ruled out as the dominant component of the galactic dark matter by nuclear recoil experiments.

Stealth Dark Matter: Dark scalar baryons through the Higgs portal [PDF]
, 2015 We present a new model of "Stealth Dark Matter": a composite baryonic scalar of an $SU(N_D)$ strongly-coupled theory with even $N_D \geq 4$. All mass scales are technically natural, and dark matter stability is automatic without imposing an additional ...

Electroweak vacuum stability and inflation via nonminimal derivative couplings to gravity [PDF]
, 2015 We show that the Standard Model vacuum can be stabilized if all particle propagators are non-minimally coupled to gravity. This is due to a Higgs-background dependent redefinition of the Standard Model fields: in terms of canonical variables and in the ...

Two Micron‐Size Dark Dimensions
Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Probing new physics of cubic Higgs boson interaction via Higgs pair production at hadron colliders [PDF]
, 2015 Despite the discovery of a Higgs boson h(125 GeV) at the LHC Run-1, its self-interaction has fully evaded direct experimental probe so far. Such self-interaction is vital for electroweak symmetry breaking, vacuum stability, electroweak phase transition ...

Simulation of a Three‐Nucleons System Transition on Quantum Circuits
Advanced Quantum Technologies, Volume 8, Issue 5, May 2025.A general procedure is presented to calculate the transition probability for two nuclear states and a transition operator. The ground state is approximated through the variational quantum eigensolver and the first excited one using more sophisticated variational algorithms.

Signals of composite electroweak-neutral Dark Matter: LHC/Direct Detection interplay
, 2010 In a strong-coupling picture of ElectroWeak Symmetry Breaking, a composite electroweak-neutral state in the TeV mass range, carrying a global (quasi-)conserved charge, makes a plausible Dark Matter (DM) candidate, with the ongoing direct DM searches ...
