Freeze-in produced dark matter in the ultra-relativistic regime
Simone Biondini, Jacopo Ghiglieri
When dark matter particles only feebly interact with plasma constituents in the early universe, they never reach thermal equilibrium. As opposed to the freeze-out mechanism, where…
The hierarchy problem and fine-tuning in a decoupling approach to multi-scale effective potentials
Simone Biondini, Daniël Boer, Ruud Peeters
In many realizations of beyond the Standard Model theories, new massive particles are introduced, leading to a multi-scale system with widely separated energy scales. In this setti…
Perturbative unitarity bounds for fermions composite models
Simone Biondini
Perturbative unitarity is a powerful tool for inferring the range of validity of a given effective field theory. Here, we study such a bound in the parameter space of dimension-5 a…
Dark matter and Standard Model reheating from conformal GUT inflation
Simone Biondini, K. Sravan Kumar
Spontaneous breaking of conformal symmetry has been widely exploited in successful model building of both inflationary cosmology and particle physics phenomenology. Conformal Grand…
