Composite Higgs bosons from neutrino condensates in an inverted see-saw scenario
We present a realization of the idea that the Higgs boson is mainly a bound state of neutrinos induced by strong four-fermion interactions. The conflicts of this idea with the measured values of the top quark and Higgs boson masses are overcome by introducing, in addition to the right-handed neutrino, a new fermion singlet, which, at low energies, implements the inverse see-saw mechanism. The singlet fermions also develop a scalar bound state which mixes with the Higgs boson. This allows us to obtain a small Higgs boson mass even if the couplings are large, as required in composite scalar scenarios. The model gives the correct masses for the top quark and Higgs boson for compositeness scale…
New scalars at the origin of dark matter and anomalies in magnetic moments
In the next paragraphs we will present the main goals of this doctoral thesis, and will try to guide the reader through the concepts that will be discussed in what follows. Basically, we have focused on two topics: the interplay between neutral scalars and the anomalous magnetic moment (AMM) of charged leptons, and dark matter (DM). Let us begin by summarising the full structure of the thesis, which is basically divided into four parts, namely: - Part I: Introductory concepts. In Chapter 1, we will briefly review the construction and main ingredients of the Standard Model (SM) of particle physics. Despite the fact that its predictions have been tested with a great accuracy, see e.g. the ele…
