new luminosity records at #LHC proton proton collisions both per 24 hours and 7 day rate:

number of charged particles created in a typical LHC collision, compared to the best simulation on the market

Particle physicists use simulations to distinguish new findings from background collisions at the LHC. This #CMSPaper examines the effectiveness of these simulations, identifying their strengths and weaknesses to select the best tools for specific tasks. More at arxiv.org/abs/2505.17850
