CMS investigates charm-quark jets in heavy-ion collisions and finds no evidence of additional radiation inside the dead cone When lead ions collide at the Large Hadron Collider, they create an extreme state of matter known as the quark-gluon plasma…

  The CMS experiment reports the first observation of a “wake” created by a fast-moving parton in quark-gluon plasma. Wake effect in quark-gluon plasma When the LHC collides heavy nuclei, such as lead, at nearly the speed of light, it creates qu…

  The CMS experiment uses its largest sample of B mesons to date to perform a high-precision test of subtle differences between matter and antimatter. One of the greatest mysteries in physics is why our universe is made almost entirely of matter…
