| contents | We present the library {\tt ggxy}, written in {\tt C++}, which can be
used to compute partonic and hadronic cross sections for gluon-induced
processes with at least one closed heavy quark loop.
It is based on analytic ingredients which avoids, to a large extent,
expensive numerical integration. This results in significantly shorter
run-times than other similar tools.
Modifying input parameters, changing the renormalization scheme
and varying renormalization and factorization scales is straightforward.
In Version~1 of {\tt ggxy} we implement all routines which are needed to
compute partonic and hadronic cross sections for Higgs boson pair production
up to next-to-leading order in QCD. We provide flexible interfaces
and allow the user to interact with the built-in amplitudes at
various levels. |
