History
The ATLAS IFIC-TDAQ Group develops its research activities as part of the international collaboration of the ATLAS experiment at the LHC at CERN. ATLAS comprises 3000 researchers from approximately 181 institutions across 41 countries worldwide, making it one of the largest collaborative efforts in science. About 1200 doctoral students are involved in operating the detector, data collection, and analysis. The collaboration relies on the efforts of numerous physicists, engineers, and technical staff. Since 1996, our group has been involved in various phases of the detector’s development, including design, construction, integration, operation, data collection, and analysis. We have had significant responsibilities, led several working groups, and made notable scientific contributions throughout these phases.
Towards 2027, a tenfold increase in the number of LHC collisions is expected in the High Luminosity (HL-LHC) phase, requiring detectors to be adapted. Particularly, the entire readout electronics of the hadronic calorimeter will need to be replaced. Our group is responsible for designing new readout and data acquisition electronics for the hadronic calorimeter. This phase will significantly enhance the collider’s performance, particularly increasing the instantaneous luminosity, expected to exceed nearly ten times the nominal value of the LHC’s initial design. The new electronics are based on the development of a novel module known as the TilePPr (PreProcessor).
The group has contributed to the physics program of the ATLAS experiment since before the start of LHC collisions, notably in the field of Higgs boson physics. The group has directly, actively, and visibly contributed to measurements of H→WW and H→ττ, leading to the observation of the Higgs boson by the ATLAS and CMS experiments in 2012, resulting in the Nobel Prize in Physics awarded to P. Higgs and F. Englert in 2013. Additionally, the group has played a primary role in measurements of Higgs boson-related discoveries, such as the observation of the Higgs boson’s Yukawa interaction in 2015 and the interaction between the top quark and the Higgs boson in 2018. Furthermore, the group has been prominent in measurements of Higgs boson pair production, which could confirm the Higgs boson’s self-interaction (“self-coupling”) and lead to the discovery of new particles that decay into Higgs bosons. The group also contributes to the search for new physics related to the Higgs sector and Supersymmetry theories.
