Search for fractionally charged particles in pp collisions at sqrt(s) = 7 TeV

Understand

A search is presented for free heavy long-lived fractionally charged particles produced in pp collisions at sqrt(s) = 7 TeV.

• The data sample was recorded by the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 inverse femtobarns.
• Candidate fractionally charged particles are identified by selecting tracks with associated low charge measurements in the silicon tracking detector.
• Observations are found to be consistent with expectations for background processes.
