Precision Higgs measurements
The discovery of the Higgs boson ten years ago and successful measurement of the Higgs boson couplings to third generation fermions by ATLAS and CMS mark great milestones for HEP. The much weaker coupling to the second generation quarks predicted by the SM makes the measurement of the Higgs-charm coupling much more challenging. With the Run3 data collected by the CMS experiment, a lot of...

To fully characterize the Higgs boson, it is important to establish whether it presents properties that are not expected in the Standard Model of particle physics. In this talk we will present the most recent measurements from the CMS experiment of Higgs properties probing BSM effects, including anomalous couplings, CP violations, polarizations.

The mass and width of the Higgs boson are its key properties. The Higgs boson mass is a free parameter of the SM that is closely related to the stability of the universe. The Higgs boson width, on the other hand, reflects the overall interactions involved in Higgs boson decays and is hence sensitive to new physics. This talk presents the latest measurements of Higgs boson mass and width from...

An important aspect of the Higgs boson physics programme at the LHC is to determine all the properties of this particle, including its mass, which is a free parameter in the SM, and its width. This presentation will discuss the latest developments in measurements of the Higgs boson mass and width, with data collected by the CMS experiment at a centre of mass energy of 13 TeV.

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 qT-slicing formalism, we obtain the first fully differential predictions for this process at next-to-next-to-next-to-leading order (N3LO) in perturbative QCD. In the boosted regime, the N3LO corrections are about +2%, and remain outside the scale...

The $H\rightarrow\tau\tau$ channel is one of the most sensitive probes of CP violation in the Higgs sector, essential for understanding the origin of the baryon asymmetry of the universe. The CP properties of the tau Yukawa coupling affect the spin correlations between the tau leptons, which can be measured by analysing the angular correlations between the tau lepton decay products. These spin...

Higgs boson production in association with a bottom-quark pair offers a direct probe of the bottom-quark Yukawa coupling and is an important ingredient in both Standard Model precision studies and searches for new physics. In this talk, I will present some of the latest results on the topic, part of the bbH/bH contribution to the LHCHWG Report 5.

The application of quantum-information-inspired observables to particle physics has attracted rapidly growing interest from both theorists and experimentalists studying spin correlations. The Higgs boson and its decay products offer an especially promising testing ground: the scalar nature of the Higgs imposes strong symmetry constraints on the spins of its decay products, yielding a state...

The anticipated precision of Higgs-sector studies at the HL-LHC calls for a theoretical description of $t \bar t$-associated Higgs production in terms of exact matrix elements for the full $2\to7$ process $pp \to b\bar{b}\,e^{+}\nu_{e}\,\mu^{-}\bar{\nu}_{\mu} + H$. Computed with massive $b$ quarks, including the off-shell production and chain decays of the $t\bar{t}H$ and $tWH$ intermediate...

The full set of data collected by CMS experiment allows searches for rare processes of the Higgs boson, subdominant with respect to the ones already observed at the LHC, by using a variety of decay modes profiting the ones with largest expected branching fractions. They include final states with a Z and a photon. Double Higgs boson production associated with a pair of top quarks is also considered.

We present a detailed NLO+PS study of Higgs-boson production in association with charm and bottom quarks (H+HF), with particular focus on H+c. We compare predictions in the massive (3FS/4FS) and massless (4FS/5FS) flavour schemes, quantifying scale and flavour-scheme uncertainties and assessing the impact of interference and loop-induced contributions to the H+c cross section.

Control over high-energy logarithms in predictions for LHC processes is increasingly important. In a recent ATLAS measurement [arXiv:2403.02793], state-of-the-art matched parton-shower predictions for an electroweak boson in association with at least two jets $(pp\to\{\gamma,Z,W\}+jj)$ deviate systematically from data as the partonic collision energy grows. This effect is due to the dominance...
