The expected Tevatron (one experiment) statistics with 8 fb-1 are shown as a comparison benchmark. For the di-lepton ('llbb') analysis, no b-tagging is used, neither for Tevatron, nor for ATLAS. For the semi-leptonic ('l+jets') analysis, a mature Tevatron analysis requiring 1 b-tagged jet is compared to an ATLAS analysis tuned for early data, without b-tagging, but providing a useful S/B ratio.

The study was performed by scaling 14 TeV full simulation results to lower Ecm values according to the top-pair production cross-section.

This page contains plots prepared by ATLAS for the LHC Chamonix 2009 meeting, on the centre-of-mass energy dependence of both calibration sample statistics and new physics reach. These plots were made for presentation at the LHC machine workshop. They are intended to illustrate the interest of operating LHC at different centre-of-mass energies and for different integrated luminosity, not to give detailed assessments of ATLAS physics capabilities. For those, see the recently released summary volume:

and the ATLAS results pages.

  Plots presented all use simpler techniques and approximations than is usual for ATLAS results, in order to have a rapid turn-around of information that could be used to inform the LHC operating strategy.

Integrated luminosity needed, as a function of centre-of-mass energy, to approach the reach of a single Tevatron experiment with 8 fb-1 of data, for a Standard Model Higgs mass of 160 GeV. This Tevatron experiment sensitivity was estimated in December 2008, and improvements in Tevatron analyses will tend to make it pessimistic.
 For the ATLAS estimate only the gluon-fusion Higgs production channel, and leptonic W decays, are considered. The overall sensitivity is approximately 1.9 sigma.

For muons, 20k Z to muon-pair decays should be sufficient to test the muon system overall momentum scale to better than 1% (systematic uncertainties are expected from alignment, knowledge of the magnetic field and energy loss).

To set the scale, it should be possible to inter-calibrate, in 0.2x0.4 eta-phi bins, the EM calorimeter to 0.7% statistical error with 25k Z to ee decays, with the error scaling approximately as 1/sqrt(N).

For muons, 20k Z to muon-pair decays should be sufficient to test separately the muon system momentum scale, alignment and calorimeter energy-loss corrections to better than 1%.

Expected sensitivity to production of a sequential Standard Model-like Z' for Z' masses of 1 and 1.5 TeV, as a function of centre-of-mass energy. The current Tevatron 95% CL lower limit is around 1 TeV. The discovery potential shown corresponds to a signal of at least ten events, which is expected to be rather more than 5 sigma.

Study carried out with fast simulation.

Around 100 pb-1 are needed to obtain discovery potential just beyond the Tevatron limits at 10 TeV centre-of-mass energy.

Expected sensitivity to production of a sequential Standard Model-like W' for W' masses of 1 and 1.5 TeV, as a function of centre-of-mass energy. The current Tevatron 95% CL lower limit is around 1 TeV. The discovery potential shown corresponds to a signal of at least ten events, which is expected to be rather more than 5 sigma.

Study carried out with fast simulation.

Around 20 pb-1 are needed to obtain discovery potential just beyond the Tevatron limits at 10 TeV centre-of-mass energy. This analysis will require a reasonable understanding of backgrounds and detector performance, which will require time to obtain.

Discovery sensitivity possible for SUSY, in an mSUGRA model with equal mass squarks and gluinos. The lepton plus jets plus missing-Et channel is employed, as this should be understood more rapidly than the statistically more powerful inclusive jets+missing-Et channel. The current Tevatron limit in this model is at around 380 GeV - discovery sensitivity beyond this should be accessible with a few tens of pb-1 at 10 TeV. The sensitivity drops away rather quickly below 8 TeV.

Study carried out with fast simulation.

Signal significance possible for the decay of a Standard Model Higgs to W pairs, summing both gluon-fusion and vector-boson fusion channels. Only leptonic W decays are used. Significance is shown as a function of centre-of-mass energy for 1 fb-1 of well-understood data. Other channels (H to ZZ and H to two photons) will also contribute, but are not included.

Mixed fast and full (GEANT4) simulation study for the mixed electron/muon W decays using a cut-based approach, with a scale factor applied to account for the double-electron and double-muon decay channels, and expected analysis improvements.

Five sigma discovery sensitivity opens up with 1 fb-1 and a centre-of-mass energy of close to 10 TeV, for the most favourable Higgs masses (160-170 GeV).

Integrated luminosity needed, as a function of centre-of-mass energy, to match the reach of a single Tevatron experiment with 8 fb-1 of data, for a Standard Model Higgs mass of 160 GeV. Only the gluon-fusion Higgs production channel, and leptonic W decays, are considered. The overall sensitivity is approximately 1.9 sigma.

Full (GEANT4) simulation study for the mixed electron/muon W decays, using a cut-based approach, with a scale factor applied to account for the double-electron and double-muon decay channels.

Overall luminosity scale uncertainty is significant, perhaps +-50%. With 200 pb-1 of 10 TeV data, a similar or better sensitivity should be accessible compared to a Tevatron experiment.

Yield of Z decays to electron pairs within the ATLAS acceptance. Yield is evaluated with full simulation at 14 TeV, as described in CERN-OPEN-2008-020 and scaled to lower centre-of-mass energies using a fast simulation with simple fiducial acceptance cuts. Error bars quoted reflect...

ATLAS Results

This page documents results prepared by ATLAS for the LHC Chamonix 2009 meeting on the centre-of-mass energy dependence of both calibration sample statistics and new physics reach.

Plots presented all use simpler techniques and approximations than is usual for ATLAS results, in order to have a rapid turn-around of information that could be used to inform the LHC operating strategy.

For more information, contact the physics coordinator, Dave Charlton or deputy physics coordinator Tom LeCompte.
