N(N)LO Tools
The primary aim is to discuss what higher order tools
are required to maximise the physics return of the
LHC and assist the experimenters in analysing data.
The Experimental Needs subgroup will be tasked with
compiling a list of required tools and providing a
list of those tools that are required and still to be
constructed.
The Higgs subgroup will focus on issues connected
with the Higgs signal and backgrounds, and
generators, bearing in mind the needs for first
detecting the Higgs and second measuring the
properties of the Higgs.
The NLO subgroup will focus on methods and algorithms
for automating the production of NLO codes for
arbitrary multiparticle final states, including both
massless and massive particles, the numerical
evaluation of loop integrals and the interface with
the parton shower.
The main issues in the NNLO session will be the
handling of the double unresolved real radiation
contributions, new methods for evaluating the phase
space integrals, two-loop integrals and the assembly
of the various contributions to give predictions for
physical observables.
