Description
We present an analytical approach for the calculation of the top quark contribution to the two-loop electroweak 𝑔𝑔 → 𝐻𝐻 amplitude. The amplitude is considered in the forward limit, where the Mandelstam variable 𝑡 is small. We expand the amplitude at the level of the integrands and obtain good approximations for large parts of the phase space.
