Replacement of the heart of the CMS experiment - the pixel detector, Part2 Date: 07-03-2017 This week, one of the Large Hadron Collider?s experiments gets a ?heart transplant?. --- Physicists and engineers are replacing the heart of the CMS experiment - the pixel #detector. This will improve CMS?s ability to make precise measurements on aspects of the Standard Model, including the properties of the #HiggsBoson. The #LHC and its experiments are currently preparing to wake up this spring, when the accelerator will begin to collide particles once more at close to the speed of light.
