ATLAS

Did you see it?

Boston University physicist Tulika Bose explains why there’s more than one large, general-purpose particle detector at the Large Hadron Collider.

The CMS and ATLAS experiments combined forces to more precisely measure properties of the Higgs boson. Sticking with the philosophy that two experiments are better than one, scientists from the ATLAS and CMS collaborations presented combined measurements of other Higgs properties at the third annual Large Hadron Collider Physics Conference in St. Petersburg, Russia.

Two experimental collaborations at the Large Hadron Collider, located at CERN laboratory near Geneva, Switzerland, announced today that they have significantly narrowed the mass region in which the Higgs boson could be hiding.

An international collaboration of scientists today sent the first beam of protons zooming at nearly the speed of light around the world’s most powerful particle accelerator-the Large Hadron Collider (LHC) located at the CERN laboratory near Geneva, Switzerland
