2010
HLT MR450
Higher single lepton trigger thresholds bias low MR distribution – prevents side-band measurements as in 2010 data
Solution: R+MR+lepton x-triggers (e.g. Mu8+R+MR and Ele10+R+MR – see Massimiliano’s talk)
Dedicated R+MR triggers (+lepton, b-tag and gamma x-triggers) will allow for offline shape analyses of MR distribution in side-bands

2. 2011 Razor Outlook Changes w.r.t. 2010 analysis:
Dedicated R+MR triggers will allow more control of MR shape
no HT trigger to unfold as in last year
R+MR x-triggers will keep lepton/gamma/b-tag thresholds low
Move from cut-and-count to ML Fit
Full MR distribution shape was modeled w/ 2010 data but largely unused in cut-and-count – will now exploit this information
Expand to new final states

Single and di-gamma
