Description
In this talk I will present the computation of the analytical NLO virtual corrections to the $gg\rightarrow HH$ cross section. The reducible contributions, given by the double-triangle diagrams, are evaluated exactly while the two-loop irreducible diagrams are evaluated by an asymptotic expansion in heavy top quark mass. I will briefly describe the techniques involved and their range of validity, and compare our computation with the known numerical results.
