Ruben Gargiulo (Sapienza Universita e INFN, Roma I (IT))05/11/2024, 09:00Precision Higgs measurements and calculations
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. Both direct and...

The total width of the Higgs boson is an important parameter for Higgs sector phenomenology. It is too small to be measured directly at the LHC, but indirect measurements can be performed using the off-shell Higgs boson production process in the ZZ and WW final states, as well as through interference effects in the diphoton decay channel. This talk presents the most recent indirect width...

Jonas Strandberg (KTH Royal Institute of Technology (SE))05/11/2024, 09:40Precision Higgs measurements and calculations
The Higgs boson decay to two vector bosons can be used to perform some of the most precise measurements of the Higgs boson production cross sections. This talk presents the more recent Higgs boson cross section measurements by the ATLAS experiment in the W boson decay channel. Interpretations of these results in the context of Standard Model effective field theories will be presented. The...

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 2 of the LHC by the CMS experiment are used. We also present interpretations of these...

Aliaksei Kachanovich (ULB)05/11/2024, 10:20Precision Higgs measurements and calculations
We present new calculations of the leading-order one-loop amplitude and the decay rate for $H\to \nu \bar{\nu} \gamma$ within the Standard Model. We present the full reduction of the Amplitude to a set of basic Passarino-Veltman functions resulting in more concise expressions compared to prior works. In this work we obtained the total decay rate as $\Gamma(H\to \nu\bar{\nu}...
