This page documents the snowmass2013 activities from LPC in the Higgs group.

Overview

We plan to study the precision of the coupling measurements in both LHC and ILC.

  • n-D fits in LHC
  • 1D fits in LHC
  • n-D fits in ee->Z(ll)H(bb)
  • 1D fits in ee->Z(ll)H(bb)

ILC Target luminosity and machine parameters

250/fb at 250 GeV; 350/fb at 350 GeV; 500/fb at 500 GeV; 1000/fb at 1000 GeV

LHC Target Luminosities and sqrt(s)

300/fb at 14 TeV; 3000/fb at 14 TeV

LHC Based Analysis

Multidimensional fits

  • Fits on the 2e2mu channel
  • The acceptance effects
  • The 4e/4mu interference effects

ILC Based Analysis

Goal

  • SM Higgs Analytical distributions
  • Validate the new generator for other spin 0 hypotheses
  • Multidimensional fits

Signal and background yields per/fb

* Proposed scenarios (with reference to Snowmass report)

sqrt(s) XS BR XS*BR lumi Nsig (raw) Nsig Nbkg
250 GeV 240 fb 0.0673*0.577 9.35 fb 250 /fb 2337 2000 400
350 GeV 129 fb 0.0673*0.577 5.03 fb 350 /fb 1760 1500 300
500 GeV 57 fb 0.0673*0.577 2.22 fb 500 /fb 1110 1000 200

sqrt(s) ee->ZH ee->ZZ
250 200fb 1300fb

  • Yield per fb
sqrt(s) ee->Z(ee,mm)H(bb) ee->Z(ee/mm)Z(bb)
250 200*0.0336*2*0.579= 7.8 1300*0.0336*2*0.15= 13
500 ~50*0.0335*2.*0.579~*2* X
