Partially composite Higgs models: phenomenology and RG analysis Open
We study the phenomenology of partially composite-Higgs models where electroweak symmetry breaking is dynamically induced, and the Higgs is a mixture of a composite and an elementary state. The models considered have explicit realizations …

Neutrino mass generation and leptogenesis via pseudo-Nambu-Goldstone Higgs portal Open
We consider an extension of the Standard Model with the global symmetry-breaking pattern SO(5)/SO(4), where the Higgs boson arises as a pseudo-Nambu-Goldstone boson. The scalar content of the theory consists of a Standard-Model-like Higgs …

Vacuum alignment with and without elementary scalars Open
We systematically elucidate differences and similarities of the vacuum\nalignment issue in composite and renormalizable elementary extensions of the\nStandard Model featuring a pseudo-Goldstone Higgs. We also provide general\nconditions fo…

Neutrino masses and ordering via multimessenger astronomy Open
We define the theoretical framework and deduce the conditions under which\nmulti-messenger astronomy can provide useful information about neutrino masses\nand their ordering. The framework uses time differences between the arrival of\nneut…

A Radiatively induced Elementary Goldstone Higgs in SU(4)/Sp(4) Open
Using a $SU(4)\rightarrow Sp(4)$ pattern of chiral symmetry breaking, we investigate the pseudo-Goldstone nature of the Higgs boson in an elementary realisation that at the same time provides an ultraviolet completion. The renormalizabilit…

Radiatively induced Fermi scale and unification Open
We consider Grand Unified Theories in which the hierarchy between the\nunification and the Fermi scale emerges radiatively. Within the Pati-Salam\nframework, we show that it is possible to construct a viable model where the\nHiggs is an el…

Neutrino masses and ordering via gravitational waves, photon and neutrino detections Open
We define the theoretical framework and deduce the conditions under which multi-messenger astronomy can constrain neutrino masses and unveil their ordering. The framework uses time differences between the arrival of neutrinos and the other…

Theory and phenomenology of the elementary Goldstone Higgs boson Open
We show, via a careful analytical and numerical analysis, that a pseudo Goldstone nature of the Higgs is naturally embodied by an elementary realization that also serves as ultraviolet completion. Renormalizability married to perturbation …

The nature of massive neutrinos and multiple mechanisms in neutrinoless double beta decay Open
Determining the nature -Dirac or Majorana- of massive neutrinos is one of the most pressing and challenging problems in the field of neutrino physics. We discuss how one can possibly extract information on the couplings, if any, which migh…

Multiple Mechanisms in 2β0ν-decay Open
The 2 β 0 ν -decay can be induced by more than one lepton charge nonconserving mechanisms. We analyze some mechanisms contributing to the 2 β 0 ν decay amplitude in the general case of CP nonconservation e.g. light Majorana neutrino exchan…
