Description
The CMS high-resolution electromagnetic calorimeter (ECAL)
comprises 75848 lead tungstate (PbWO4) crystals and is
optimized for the discovery of the SM Higgs boson in its twophoton
decay mode. With the unprecedented collision rate at
the Large Hadron Collider (LHC), the electron/photon (EG)
Trigger plays a major role in selecting the collisions most
likely to yield something new and interesting. Since start of
physics in March 2010 the LHC instantaneous luminosity has
increased by six orders of magnitude to more than 10e33
cm-2 s-1 today, presenting a major challenge for the stability
of the trigger system. This poster presents the performance
of the EG trigger based on data recorded by the CMS
detector in 2011.
