---+ !SWGuideHLTriggerOffline/Higgs Package description

The offline trigger efficiency code is (not yet) located in  [[http://cmssw.cvs.cern.ch/cgi-bin/cmssw.cgi/CMSSW/SWGuideHLTriggerOffline/Higgs][SWGuideHLTriggerOffline/Higgs]] 

---++ Samples

For the validation of main Higgs analyses the following samples are requested for the
given Higgs masses.


   * %$ H^+\rightarrow\tau\nu$%, M=200 GeV
   * %$ H\rightarrow 2\gamma$% (gluonfusion), M=130 GeV
   * %$H\rightarrow ZZ\rightarrow 4l$%, M=130, 200 GeV
   * %$H\rightarrow WW\rightarrow 2l$%, M=130, 165 GeV
   * %$qqh\rightarrow 2\tau\rightarrow  l + \rm jet}_\tau $%, M=135 GeV
   * %$qqh\rightarrow {\rm invisible}$%, M=120 GeV
   * %$A\rightarrow 2\mu$%, M=115 GeV

---++ Validation Results

*NOTE:* in the results below L1 refers to the final L1 decision, not to the
bits actually used by the Higgs-relant HLT. (Should be changed in the code)
