In what follows the combined trigger will be referred to as the \e+eTau" trigger.
The CMS High Level Trigger
The combined trigger has a reduced threshold on the electron, compared to the single-electron trigger, and obtains an HLT e–ciency of 70% at both low and high luminosity.
The CMS High Level Trigger
The overall e–ciency of the combined trigger is only about 2-5% higher than the one obtained by the single electron trigger, but this is mostly due to the choice of a relatively high mass for the Higgs.
