Scientists from the CMS and ATLAS experiments presented their first results from analysis of the proton-proton collision data collected in 2015. Fermilab and university scientists, working together at the LHC Physics Center, have played leading roles in some of the new results from CMS.
On July 21, CMS submitted for publication the first physics paper using the Run II data. The analysis studied the most common collisions to characterize both the number and direction of charged particles created in the collisions.
After a two-year shutdown, the LHC roared back to life earlier this summer, delivering proton-proton collisions at an energy of 13 TeV, significantly higher than the 8-TeV collisions of Run 1.
