Introduction

In this project the student will be studying the feasibility of the Higgs search with the ATLAS detector at the Large Hadron Collider (LHC), in a given Higgs search channel or channels.

The student is advised to read about the LHC, its physics programme, and past and ongoing searches for the Higgs boson. Select some papers from this list of overview papers.

The fractions of signal and background events that will contribute to a particular final state (eg, tt-->bqq blv) should be calculated using this table of Branching Ratios (BR) (from PYTHIA 6.323). It contains useful data on the BRs of Higgs, W and Z bosons, tau leptons, and more.

ATLFAST ntuples

  Information on the simulated samples can be found in my Log Book 11, page 23.

All of the samples below include simulation of the underlying event. PYTHIA 6.323 was used to generate the events. The cross-sections quoted below are those provided by PYTHIA (except where explicitly stated otherwise). (See page 36 of Log Book 11 for more details.) The fast simulation ntuples include Run No and Event No information.

The cross-sections quoted below are those provided by PYTHIA (except where explicitly stated otherwise). (See page 36 of Log Book 11 for more details.) The fast simulation of the detector response was carried out with ATLFAST 11.0.5, and the ATLFAST ntuples include Run No and Event No information.
