Current status of the Higgs Boson Properties Measurements and the Development of New Technologies for Future Discoveries at CERN

• Toni Sculac (University of Split Faculty of Science (HR))

Room: Hornets Nest (WH8X) Toni Šćulac is currently spending three months at Fermilab as a Visiting Researcher coming from University of Split, contributing to the upgrade of the High Granularity CALorimeter (HGCAL) for the CMS experiment at CERN. Over the past decade, he has played a key role in precision measurements of the Higgs boson properties in the so-called “golden channel” (H → ZZ → 4l), one of the most sensitive probes of the Higgs sector. In this talk, he will briefly revisit the landmark discovery of the Higgs boson in 2012, before delving into the current status of Higgs boson property measurements and their implications for new physics beyond the Standard Model. He will then shift focus to the future, highlighting the latest developments in the HGCAL detector upgrade, a major technological leap for the High-Luminosity LHC era. Special emphasis will be placed on the contributions of the group from Split, particularly in the design and testing of the ECON concentrator ASICs and the development of backend trigger firmware based on FPGA technology.
