Compositeness is an elegant way to address the hierarchy problem. In this talk, under broad assumption of partial compositeness and Higgs doublet as the pseudo-Nambu-Goldstone bosons, I will discuss about phenomenology of the spin-1 resonances and the top partners in CHMs and the relevance of their strong interactions in the searches at the LHC. I will also discuss about the strong...

In this talk, I will present a novel realization of a composite Higgs, which can naturally produce top partners above the current LHC bounds without increasing the tuning above 10%. This is achieved by combining softened breaking of the Higgs shift symmetry with an enhanced ('maximal') symmetry of the composite sector, which turn out to perfectly complement each other. I will finally provide a...

The production of doubly charged Higgs bosons $\Delta^{\pm\pm}$ in high-$p_T$ proton collisions is a key prediction of several new physics scenarios, particularly the Type II Seesaw model for neutrino masses. We present a state-of-the-art and systematic comparison of $\Delta^{\pm\pm}$ production mechanisms, emphasizing the importance of higher-order corrections and subdominant channels. For...

The Higgs boson could provide the key to discover new physics at the Large Hadron Collider. We investigate novel decays of the Standard Model (SM) Higgs boson into leptophobic gauge bosons which can be light in agreement with all experimental constraints. We study the associated production of the SM Higgs and the leptophobic gauge boson that could be crucial to test the existence of a...

We investigate the prospects for discovering a top quark decaying into

one light Higgs boson ($h^0$) along with a charm quark
in top quark pair production at the CERN Large Hadron Collider (LHC)
and future hadron colliders.
A general two Higgs doublet model is adopted to study the signature
of flavor changing neutral Higgs (FCNH) interactions with $t \to c h^0$,
followed by $h^0... -

The increase in luminosity and center of mass energy at the FCC-hh will open up new clean channels where BSM contributions are enhanced at high energy. In this paper, we study one such channel, $Wh \to \ell\nu\gamma\gamma$. We estimate the sensitivity to the $\mathcal{O}_{\varphi q}^{(3)}, \, \mathcal{O}_{\varphi\text{W}}$, and $\mathcal{O}_{\varphi\widetilde{\text{W}}}$ SMEFT operators. We...

The naturalness problem motivates new physics beyond the Standard Model (SM). The Higgs sector in neutral naturalness models provides a portal to the hidden QCD sector, and thus Higgs coupling measurements play a central role in exploring the model parameter space. We investigate several classes of neutral naturalness models, in which the Higgs boson is a pseudo-Goldstone boson with the...
