experiments represents a major breakthrough in our understanding of the mechanism of the electroweak symmetry breaking.
Current measurements of the spin and parity of this new particle, as well as the investigation of its couplings to other SM particles, revealed no significant... -

Study of the CP parity of a Higgs boson and its anomalous couplings to gauge bosons or fermions is one of the priorities of the LHC and future Higgs factories. We present a coherent framework for the measurement of anomalous couplings of the Higgs boson to two weak vector bosons using the decay, vector boson fusion production, and associated production with a vector boson, where both on-shell...

At the LHC, the most promising channel for probing the coupling of the Higgs field to the quarks and leptons are H->bb and H->tautau, respectively. In this talk I will be presenting the latest ATLAS results on these two channels. The rare H->mumu decay is also investigated. In many scenarios beyond the standard model (BSM) the couplings of the Higgs to fermions is altered. In ATLAS many BSM...

We study the Higgs boson $(h)$ decay to two light jets at the 14 TeV High-Luminosity-LHC (HL-LHC), where a light jet ($j$) represents any non-flavor tagged jet from the observational point of view.

% On the theory side, $j$ is a gluon as expected in the Standard Model}.
The decay mode $h\to gg$ is chosen as the benchmark since it is the dominant channel in the Standard Model (SM), but the... -

The radiative decays of the Higgs boson to a fermion pair $h\rightarrow f\bar{f}\gamma$ is revisited, where $f$ denotes a fermion in the Standard Model (SM). Both the chirality-flipping diagrams via the Yukawa couplings at the order $\mathcal{O}(y_f^2 \alpha)$, and the chirality-conserving contributions via the top-quark loops of the order $\mathcal{O}(y_t^2 \alpha^3)$ and the electroweak...

The measurement of the Higgs trilinear coupling through Higgs pair production is particularly challenging. We explore the possibility of probing the trilinear coupling indirectly, through the production and decay of a single Higgs. The method relies on the effects that electroweak

Recently it has been suggested that precision single-Higgs measurements offer an alternative approach to the extraction of the Higgs self coupling with respect the traditional double-Higgs searches. We study how to obtain a parametrically enhanced deviation of the Higgs self-coupling and we estimate how large this deviation can be in a self-consistent EFT framework. We perform a global study...
