• LPC experts contributed to the performance of key physics ingredients such as tracking and vertexing, triggering, jets, b-tagging, muons,
electrons, taus, photons, and missing energy
LPC contributions to LHC physics
The LHC Physics Center at FNAL
The LPC at Fermilab and the Higgs discoveryhttp://lpc.fnal.gov
User facilities and activities at the LPC
•More than 350 users and 100 residents•LPC users directly contributed to 50% of ~200 CMS publicationsThe LPC is a way to attain critical mass for 50 U.S. university groups
The LPC is a nexus for diverse synergistic contributions across a broad range of R&D areas •Includes facilities on-site for detector design and fabrication, software development and physics data analysis•The Remote Operations Center enables US-based physicists to participate in real-time as members of the detector operations shift crew.
•The LPC has transformed the way the CMS collaboration educates young students and post-docs•CMS Data Analysis School established at the LPC for new collaborators
•The LPC hosts distinguished visiting scientists and fosters interactions with off-site collaborators and theorists through seminars, workshops, and hands-on tutorials.
• The LPC is the local (US) center of excellence for CMS physics
•The LPC serves as a critical link for remote physicists to participate directly in the CMS experiment effectively, economically and
transparently.

• Members from the LPC played an important role in the data analysis for the main Higgs search channels
• H → ZZ → 4l• “the golden channel”,• versatile mode with clean,
distinctive signature
• H → WW → lνlν•“the workhorse channel”• sensitive over a large
search mass range•
• H → bb and H → ττ• challenging search modes probing
couplings of the Higgs to fermions
•
•Nearly 700 CMS collaborators use the Fermilab LPC computing cluster with 22 Pb of storage and 3300 local and 6400 global nodes for data processing and analysis
