From Run 3 to the next generation: following the transformation of the LHC experiments
From dismantling detector components to installing new technologies, the transition from Run 3 to the next generation of LHC experiments is a major scientific and engineering undertaking. We follow the teams behind this transformation, exploring the challenges inside the experimental caverns and the expertise across CERN’s EP Department that helps turn ambitious upgrade plans into…

From beam dumps to missing energy: the SPS search for hidden particles
For more than four decades, CERN’s Super Proton Synchrotron has served as a testing ground for new ways to search for particles that interact only feebly with ordinary matter. In a recent lecture, NA64 co-spokesperson Paolo Crivelli traced the evolution of this programme – from the first beam-dump experiments to missing-energy and missing-momentum searches, precision…

NA62 experiment at CERN reports first evidence for ultra-rare process sensitive to new physics
NA62 experiment at CERN reports first evidence for ultra-rare process sensitive to new physics The CERN NA62 collaboration presented at the ICHEP 2020 conference the first significant experimental evidence for the ultra-rare decay of the charged kaon into a charged pion and two neutrinos (K+ -> π+νν). The decay process is very sensitive to deviations
