Quark and gluon spin-2 form factors to two loops in QCD
We present two-loop QCD corrections to the quark form factor from the amplitude G∗ → qq¯ and the gluon form factor from G∗ → gg in SU(N) gauge theory with nf light flavours. We use ddimensional regularisation and the results are presented to all orders in ε = d - 4. These form factors can be used to...
