The first wafers of the CMS Read Out Chip (CROC) for the High Luminosity Pixel detector have been produced and tested, marking a major milestone for the next generation CMS Tracker. Each silicon wafer contains 136 chips that are built to withstand t…

  New in! CMS physicists search for heavy cousins of the neutrino in beauty meson decays Back in 2018, the physicists of the CMS experiment designed and recorded a B-meson-enriched data sample, the “B-Parking” data set. The B mesons (short for beauty…

When we look at ourselves in a mirror, we see a virtual twin, identical but with left and right inverted. Charge-parity (CP) is the equivalent of a mirror for fundamental particles. If the symmetry was respected in nature, each particle would see a c…
