Objectives:

The main purpose of this research proposal is to discover or exclude
the Standard Model Higgs boson. Specifically, I intend to do this in
the challenging region of low Higgs mass, between the LEP limit of
114GeV/c2 and around 140 GeV/c2, which is favoured by the presently
known experimental data. To do this, I propose to investigate the ttH
channel, and concentrate on the "all-lepton" final state, where the
decay of the top quarks produces two high-transverse momentum leptons
and four b quarks.

Before attempting to search for the Higgs boson, I intend to continue
to develop my work in the ATLAS trigger. Some of my goals in this area
will be to ensure that the optimal triggers exist that can select as
many Higgs events as possible, and to guarantee that these triggers
are well understood and monitored. An additional goal will be to
ensure the trigger online information and configuration will be
reliable and easily available, which would be beneficial for physics
analysis.

I also intend to contribute to the first top-antitop cross section
measurement in ATLAS. In addition to being a goal on its own, this
would be essential preparation for a Higgs boson search in the ttH
channel.

If a Higgs boson is discovered, my next step will be to measure its CP
property, to help determine the nature of the particle found. The
Standard Model predicts a CP-even Higgs boson, and so a measurement
which excludes this possibility could provide an essential element to
determining the underlying theoretical model.
