Two-loop virtual corrections to Higgs pair production

Mostrar todas las versiones(3)

We present the two-loop virtual corrections to Standard Model Higgs boson pair production via gluon fusion gg→ HH in the heavy top quark limit. Based on this result, we evaluate the corresponding cross section at the LHC at 14 TeV in the next-to-next-to-leading order soft-virtual approximation. We f...
