The online muon identification with the ATLAS eExperiment at
the LHC

  The Large Hadron Collider (LHC) at CERN is a proton-proton
  collider providing the highest energy and the highest
  instantaneous luminosity ever achieved at a hadron collider.
  During 2012 runs, bunch crossings occurred every 50 ns. 

  Muons provide a clear signature for many physics processes.
  They therefore often play an important role in physics
  analyses such as the recent discovery of a Higgs boson. 

  A full overview of the ATLAS muon trigger system is given,
  the three years of running experience are summarised and a
  report about online performance such as processing time,
  trigger rates, efficiency and resolution is given.

If you think the Large Hadron Collider is impressive, think
what particle reactions are occurring at the Cosmic Ray point
of impact where energies can be 100,000,000 times greater!
