Abstract
We present the current status of the analytical calculation of the top quark contribution to the
two-loop electroweak $gg\rightarrow HH$ amplitude. The amplitude is considered in the forward limit,
where the Mandelstam variable 𝑡 is small. By expanding in this limit at the level of the integrands,
good approximations for the amplitude can be obtained.
