A few multiplets that can be added to the SM contain a lightest neutral component which is automatically stable and provides allowed DM candidates with a non-standard phenomenology. Thanks to… (More)

In a generic “universal” theory of electroweak symmetry breaking, simple symmetry considerations and absence of tuning imply that heavy new physics affects the lowenergy data through four parameters.… (More)

We present a general analysis of extensions of the Standard Model which satisfy the criterion of Minimal Flavour Violation (MFV). We define this general framework by constructing a low-energy… (More)

We perform a thorough study of thermal leptogenesis adding finite temperature effects, RGE corrections, scatterings involving gauge bosons and by properly avoiding overcounting on-shell processes.… (More)

Taking into account spins, we classify all two-body non-relativistic Dark Matter annihilation channels to the allowed polarization states of Standard Model particles, computing the energy spectra of… (More)

We propose some scenarios to pursue dark matter searches at the LHC in a fairly model-independent way. The first benchmark case is dark matter co-annihilations with coloured particles (gluinos or… (More)

The cosmic-ray excess observed by PAMELA in the positron fraction and by FERMI and HESS in e− + e can be interpreted in terms of DM annihilations or decays into leptonic final states. Final states… (More)

We study thermal leptogenesis induced by decays of a scalar SU(2)L triplet. Despite the presence of gauge interactions, unexpected features of the Boltzmann equations make the efficiency close to… (More)

We consider DM that only couples to SM gauge bosons and fills one gauge multiplet, e.g. a fermion 5-plet (which is automatically stable), or a wino-like 3-plet. We revisit the computation of the… (More)

Baryogenesis by heavy-neutrino decay and sphaleron reprocessing of both baryon and lepton number is reconsidered, paying special attention to the flavour structure of the general evolution equations… (More)
