We propose a novel framework where baryon asymmetry can arise due to forbidden decay of dark matter (DM) enabled by finite temperature effects in the early universe. In order to implement it in a realistic setup, we consider the DM to be a singlet Dirac fermion which acquires a dark asymmetry from a scalar field $\Phi$ via Affleck-Dine mechanism. Due to finite-temperature effects, DM can decay in

Composite Higgs theories often suffer from predicting light top partners, which are excluded by collider experiments. In the recently proposed SU(6) Gauge-Higgs Grand Unified Theory by Angelescu et al., where the Higgs boson emerges as a pseudo-Nambu Goldstone boson of the coset SU(6)/SU(5), the embedding of the elementary Standard-Model fermions naturally gives rise to additional vector-like exot

Several mechanisms generating relic abundance of ALP dark matter involve processes which take place before, during or after cosmic inflation. In such cases fundamental role is played by PQ field potential. We investigate radiative, thermal and geometric corrections to PQ field dynamics in scenarios in which the potential has very small self-coupling. We will focus on models with quasi-supersymmeri

In this talk, I will discuss the so-called t-channel singularities that may occur when a given t-channel scattering process is mediated by a massive, stable particle on its mass shell.
After providing conditions for the singularity to occur and presenting several examples of SM and BSM processes afflicted by the issue, I will describe a regularization method based on thermal field theory.

Recent studies have provided evidence for the existence of new totally asymptotically free trajectories in non-Abelian particle models without asymptotic symmetry in the high-energy limit. These results have been obtained in a general SU(NL)×SU(Nc) Higgs-Yukawa model that includes the non-Abelian sector of the standard model, by means of the standard one-loop study of a generic Higgs potential (f

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. One triplet of fermions and the singlet are odd under a $Z_2$ symmetry, thus the model features two possible dark matter candidates. The two remaining $Z_2$-even triplet fermions can reproduce the neutrino masses and oscillati
