The CMS experiment at CERN recently announced the release of 13 TeV proton-proton collision data from 2016. Over 70 TB of collision data and 830 TB of corresponding simulations are now available through the CERN Open Data Portal, marking a…
Read moreResearchers using the ATLAS detector at CERN's Large Hadron Collider (LHC) have achieved a breakthrough: the first observation of quantum entanglement in top quark pairs. This discovery, analyzing proton-proton collisions at incredibly high energies…
Read moreFor a few years, the work of the LHC community has been split between the exploitation of the LHC Run2 and first Run3 data and the preparation for the High Luminosity (HL) phase. At the HL-LHC, the effort of searching for new physics will be…
Read moreThe High-Luminosity LHC upgrade will provide an unprecedented challenge to the data acquisition and online event processing capabilities of ATLAS and CMS. Both experiments are currently undergoing major upgrades to prepare their detectors to cope…
Read moreEarth Observation (EO) and particle physics research have more in common than you might think. In both environments, whether capturing fleeting particle collisions or detecting transient traces of ocean plastics, rapid and accurate data analysis is…
Read moreImprovements implemented in the CMS trigger and data acquisition systems before the start of Run 3 LHC in 2022 have enabled an increase in both the event rate and the volume of useful data collected by the CMS detector, thereby broadening its…
Read moreThe ATLAS and CMS Experiments at CERN have just released a new measurement of the mass of the top quark. The new result combines 15 previous measurements to give the most precise determination of the top-quark mass to date. Among the known…
Read moreThe LHC schedule for 2023 has been revised following the emergence of a leak in mid-July. The decision was to stop the regular proton running this year and focus on the heavy ion physics that was already scheduled for the year-end. This was…
Read moreBefore the start of the LHC Run 3, CMS improved many aspects of its trigger system in order to boost the physics reach of the experiment. To select events of potential physics interest, the CMS trigger system divides the processing into two levels:…
Read moreDIRAC and Rucio are two software projects used for scientific computing. Both projects are led by CERN, and the EP department is one of the major contributors to both. DIRAC is used by CERN experiments such as LHCb, CLIC, FCC, NA62, and non-…
