HCAL Plots

Here are electronic versions of a number of plots related to HCAL physics performance. More will be added over time.

• Physics Goals of the HCAL

• Simple diagram explaining missing ET

• "Search for Heavy Higgs in the Channel H -> WW -> l nu jet jet"

  I. Gaines et al., Fermilab-FN-634, CMS-TN/95-154, November 1995.
  Demonstrates performance for (high-pT) W reconstruction in the jet-jet channel.

  Dijet mass plots:
  signal,
  W+jets background, and
  top background
  .

• "Missing ET + jets Signals for Supersymmetry in the CMS Detector at the LHC"

  I. Gaines et al., Fermilab-FN-642, CMS-TN/96-058, June 1996.
  Missing ET performance including effects of cracks, degraded HCAL performance, and non-gaussian resolution.

  
  Figure 3 shows the pseudorapidity coverage required for missing ET (new version from Daniel Denegri).

• Simple diagram explaining h -> b b_bar search

• "On the Possibility to Observe h -> b b_bar with S/B ~ 1 in SUSY (mSUGRA)"

  S. Abdullin, CMS Note 97-070, 1997.

  
  Figure 13 shows the h -> bb mass peak reconstructed in the HCAL;

  
  Figure 21 shows the regions of MSSM parameter space where this is possible.

• Latest Missing ET Plot

  
  Showing SUSY signal visible over QCD and WZ background.

• Missing ET with and without forward calorimeter

  
  Showing the effect on missing ET resolution if the VFCAL were not present.
