With the full Run 2 pp collision dataset collected at 13 TeV, very precise measurements of Higgs boson production and decay rates can be performed, shedding light over the electroweak symmetry breaking mechanism. This talk presents these precise measurements including total and fiducial cross-sections for the main Higgs boson processes as well as branching ratios into final states with bosons...

We will discuss the latest differential measurements of Higgs boson cross sections with the CMS detector in bosonic decay channels. Both fiducial differential cross section measurements and measurements in the simplified template cross section framework will be presented. The data collected during Run 3 of the LHC by the CMS experiment are used.

Combination of measurements from different Higgs boson productions and decays will maximize the statistical power, and also allow decoupling the production from decay. This talk presents the latest combined measurements of the Higgs boson production cross-sections and decay branching ratios by the ATLAS experiment based on LHC Run 2 data, including Simplified Template Cross Sections (STXS)...

Gluon fusion, gg → HH, is the dominant Higgs-pair production process at the Large Hadron Collider (LHC) and provides the first direct access to the trilinear Higgs self-coupling. The process is loop-induced, with the leading contribution arising from top-quark loops within the Standard Model. QCD corrections for this process have been calculated up to NNLO and are known to substantially...

Di-Higgs production is the most promising experimental signature to measure the cubic Higgs self-interaction at the LHC and its high luminosity upgrade. In this talk I will report on recent progress on analytic results for the computation of di-Higgs production in controlled expansions, which cover the whole physical phase space. This encompasses recent results on NNLO virtual corrections,...

In the Standard Model, the ground state of the Higgs field is not found at zero but instead corresponds to one of the degenerate solutions minimising the Higgs potential. In turn, this spontaneous electroweak symmetry breaking provides a mechanism for the mass generation of nearly all fundamental particles. Experimentally, the Higgs boson self-coupling and thereby the shape of the Higgs...

We consider the production of a boosted Higgs boson in association with a charged weak ($W$) boson from proton-proton collisions at the LHC. Using the $q_T$-slicing formalism, we obtain the first fully differential predictions for this process at next-to-next-to-next-to-leading order (N$^3$LO) in perturbative QCD.

In the boosted regime, the N$^3$LO corrections are about $+2\%$, and remain... -

The measurement of multiboson processes including diboson and triboson offers a stringent test of the SM electroweak structure, and provides complementary ways to constrain the high precision QCD and electroweak calculations. This talk presents recent results in this sector from the ATLAS experiment.

Measurements of processes involving multiboson final states constitute a precision test of the Standard Model. Moreover, discrepancies between theoretical predictions and experimental measurements could hint to new physics through the presence of anomalous gauge couplings. These processes are also dominant backgrounds for Higgs boson measurements, and searches for new particles with diboson...

The vector boson fusion and scattering processes offer an important avenue to test the Standard Model electroweak theory, the electroweak symmetry breaking mechanism, and also QCD modelling in the relevant topologies. This talk presents recent measurements in this sector from the ATLAS experiment.

Vector boson scattering is a key production process to probe the electroweak symmetry breaking of the standard model, since it involves both self-couplings of vector bosons and coupling with the Higgs boson. If the Higgs mechanism is not the sole source of electroweak symmetry breaking, the scattering amplitude deviates from the standard model prediction at high scattering energy. Moreover,...

The measurement of diboson polarisation states in multiboson production or vector boson scattering processes offer a new opportunity to study electroweak symmetry breaking mechanism and evolution of interaction structures over energy growth, and in particular offer connections to study predictions concerning goldstone bosons. This talk presents recent measurements in this sector from the ATLAS...

Diboson production at the LHC provides a powerful probe of the electroweak sector and possible deviations from the Standard Model within the Standard Model Effective Field Theory (SMEFT). We present a study of the interplay between dimension-6 SMEFT operators and gauge boson polarization in production at $\sqrt{s}$ = 13 TeV.
The analysis is based on dedicated Monte Carlo event samples...

Searches for BSM Higgs and Additional Scalars at ATLAS The discovery of the Higgs boson with the mass of about 125 GeV completed the particle content predicted by the Standard Model. Even though this model is well established and consistent with many measurements, it is not capable of explaining some observations by itself. Many extensions of the Standard Model addressing such shortcomings...

The quest for new physics is a major aspect of the CMS experimental program. This includes models involving resonances that can decay to photons, leptons or jets. This talk presents an overview of such analyses with an emphasis on new results and the novel techniques developed by the CMS collaboration to boost the search sensitivity. The searches are carried out with data of the Run-II and...

Many theories beyond the Standard Model predict new phenomena giving rise to observable final states. Examples include Supersymmetry, Z' or W' bosons, KK gravitons, vector-like quarks/leptons or heavy leptons, or Dark Matter. Searches for new physics with such signatures, produced either resonantly or non-resonantly, are performed using the ATLAS experiment at the LHC. This talk will report...

Among the intriguing scenarios of new physics that provide explanation to several shortcomings of the Standard Model (SM), hidden valley scenarios include a Dark Sector that extends the SM with a non-Abelian gauge group, similar to quantum chromodynamics with new matter and gauge fields analogous to the SM quark and gluon fields. This may result in a rich phenomenology which we can access...
