Eight is enough

CMS goes looking for particle physics events that produce eight particles produced by new physics.

QCD is holding its own. Even at energies 63 percent higher compared to the LHC’s first run, the data produced during the current, second run bears out the decades-old predictions of QCD.

In their search for dark matter, CMS scientists invented new measurement variables, called razor variables, to enhance their capability to identify events containing dark matter.
