Higgs at the Tevatron and LHC Rick St. Denis – Glasgow University

Outline ● Higgs Decay Modes at Tev and LHC ● The two paths ● The CDF sensitivity ● Scenario ● Conclusions ● Appendix:Vector Boson Fusion Production of Higgs at TeV and LHC

ATLAS Channels M H (GeV) 55 Deliberately Ignore  Should we invest in this? W,Z we know!

CDF Channels NOW Ntupled 1fb -1 Total WH(l bb) WH-WWW VBF gg-WW ZH(llbb) ZH( bb) Used WW correction For VBF Before Selection!

CDF (2009?) For 8fb -1

The Two Paths ● H to WW depends on jets, leptons (VBF too). Same at LHC, CDF. Have studied VBF and fascinating match of detectors to machines! ● ttH depends on jets, b-jets: tagging and rmass resolution. WH,ZH depends on same: Huge synergy. Very different path. ● There are two natural divisions of effort: those that need silicon and those that don’t. We have lepton expertise and should use it!

CDF Limits: (WW:360 pb -1 ) X 12 Jet Resolution

VBF Production Features ● Missing Et ● High Pt Leptons ● 2 forward jets, opposite in rapidity, high mass ● Spin 0 Higgs correlates spins of leptons: e,  parallel and neutrinos also ●  e-jet about q q' q W+W+ W-W- H0H0 W+W+ W-W- e-e- e-e- ++ e  Same as WW, but with forward jets. Do analyses together. Very unique events.

Studies ● Backgrounds: top, fakes, WW ● WW *is* the right laboratory in any case, even if no Higgs. Something has to keep the cross section under control ● Need to get detector understood using Z’s to get e,  W’s for Missing Energy. ● Need to understand top, WW for backgrounds. ● Do the Higgs detection at the same time

Objectives for the Pilot RUN Reach a Luminosity of Low Luminosity run at 25 ns separation Difficult to speculate further on what the performance might be in the first year. As always, CERN accelerators departments will do their best ! Lyn Evans Rolandi: LP2005

Tevatron Projections

Scenario ● ATLAS 2007: Pilot Run, Z,W calib? 200pb -1 ● ATLAS 2008: Physics, 1fb -1 ● CDF 2007: 4fb -1 : HWW 4x3: at SM limit in the range. TOP and W Mass improved as well, so SM fit limits narrower. ● Deviations building from expected limit: we focus on this range for ATLAS Perhaps SM fit narrowing on this range. ● Higgs is OR Perhaps SM Fit excludes upper range. ● CDF 2009: 3  at 120: ATLAS 2011? For discovery. CDF Keeps running!? ● ATLAS 2010: 10fb -1 : Discover it for > 130.

Summary/Conclusions ● CDF/ATLAS interest in W decay modes. ● Detector expertise/studies in Z,W to leptons: Where our efforts should be. ● Some jets interest, but not absolutely needed. ● WW is the right laboratory for studying EW Sym Breaking. ● Tevatron will have clear statements from Direct and Indirect searches when LHC searchs get serious.
