Search for H→cc via ttH production at CMS
/ Wuchterl, Sebastian (speaker) (CERN)
A search for the standard model Higgs boson decaying to a charm quark-antiquark pair, H→cc, produced in association with a top quark-antiquark pair (ttH) is presented, using the LHC Run 2 dataset collected by the CMS experiment.
Advanced machine learning techniques are employed for jet flavor identification and event classification.
A simultaneous fit is performed to extract the signal strengths of ttH and ttZ production with decays to both cc and bb.
The obtained results are combined with the previous search for H→cc via associated production with a W or Z boson, setting the most stringent constraints to date on the charm Yukawa coupling.
Refreshments will be served at 10h30
2025 - 3683.

Martin Kunz: Exploring the Dark Universe with Euclid
/ Kunz, Martin (speaker) (Geneva, Switzerland)
In this Colloquium I will introduce the Euclid satellite mission and its history since the launch in Summer 2023 : the challenges that we faced, and results from the ERO and Q1 data releases. I will then look into the future to some of the cosmology results that we expect for the coming years, and what we hope to learn about the dark universe..

Revisiting the theory of spin correlations and entanglement in top pair production at the LHC
/ Nason, Paolo (speaker)
Recent ATLAS and CMS studies of spin correlations and entanglement in top pair production at hadron colliders have evidenced some inadequacy in the current modeling of the process of top pair production and decay. It has been argued that one needs to include the effect of a very short-lived $t{\bar t}$ pseudoscalar bound state to reconcile the data with the theoretical prediction. [...]

The CERN Open Hardware Licence
/ Tacchini, Dane (speaker) (CERN)
The CERN Open Hardware Licence (“CERN OHL”) was developed in 2011 to promote collaboration among hardware designers and to provide a legal tool which supports the freedom to use, study, modify, share and distribute hardware designs and products based on those designs. The second version of CERN OHL released in 2020 provides additional flexibility by introducing three CERN OHL variants – the permissive, the weakly-reciprocal and the strongly-reciprocal, thus enabling the selection of a licence adapted to the needs of each project. [...]
