Time-reversal breaking and parity-conserving millistrong interactions, suggested in 1965, still remain a viable mechanism of CP-violation beyond the Standard Model.

Higgs inflation, vacuum stability, and leptogenesis
We consider the introduction of a complex scalar field carrying a global lepton number charge to the Standard Model and the Higgs inflation framework. The conditions are investigated under which this model can simultaneously ensure Higgs vacuum stability

Sp(4) gauge theories and beyond the standard model physics [PDF]
We review numerical results for models with gauge group Sp(2N), discussing the glueball spectrum in the large-N limit, the quenched meson spectrum of Sp(4) with Dirac fermions in the fundamental and in the antisymmetric representation and the Sp(4) gauge

PRyMordial: the first three minutes, within and beyond the standard model [PDF]
In this work we present PRyMordial: A package dedicated to efficient computations of observables in the Early Universe with the focus on the cosmological era of Big Bang Nucleosynthesis (BBN).

Dark matter and lepton flavour phenomenology in a singlet-doublet scotogenic model
We study the dark matter phenomenology of scotogenic frameworks through a rather illustrative model extending the Standard Model by scalar and fermionic singlets and doublets.

Di-Higgs production in the 4b channel and gravitational wave complementarity
We present a complementarity study of gravitational waves and double Higgs production in the 4b channel, exploring the gauge singlet scalar extension of the SM.

Gravitational tests of electroweak relaxation
We consider a scenario in which the electroweak scale is stabilized via the relaxion mechanism during inflation, focussing on the case in which the back-reaction potential is generated by the confinement of new strongly interacting vector-like fermions ...

We show the presence of a potentially detectable gamma-ray line in the Fermi Galactic center excess in light of the secluded (vector) dark matter (DM) model in which the hidden scalar, nearly degenerate with DM in mass, mediates the interaction of the ...

anyH3: precise predictions for the trilinear Higgs coupling in the Standard Model and beyond [PDF]
The trilinear Higgs coupling $$\lambda _{hhh}$$ λ hhh of the detected Higgs boson is an important probe for physics beyond the Standard Model. Correspondingly, improving the precision of the theoretical predictions for this coupling as well as the ...
