What is the Method?
The Phox programs are FORTRAN codes combining analytical and
Monte-Carlo approaches, and proceed like a `partonic even generator'.
In an intermediate step of the calculation of higher order corrections to
inclusive observables, soft and collinear singularities appear at the
partonic level, separately in virtual corrections to 2 -> 2 processes, and
in real 2 -> 3 processes. The singularities in real 2 -> 3 contributions
are treated according to a method combining phase space slicing and
subtraction. Then the regularized cross section is used to generate partonic
configurations. These configurations are finally projected on histograms to
obtain the desired observables - whose values have to be independent of the
slicing used. For more details on the method, see:
