Two-loop helicity amplitudes for diphoton production with massive quark loop
Taushif Ahmed, Amlan Chakraborty, Ekta Chaubey +1
We compute two-loop helicity amplitudes in QCD for diphoton production through quark- and gluon-initiated channels, accounting for a massive internal quark loop by keeping its full…

Two-loop non-planar four-point topology with massive internal loop
Taushif Ahmed, Ekta Chaubey, Mandeep Kaur +1
We study a set of two-loop non-planar master integrals needed for the NNLO QCD corrections to diphoton and dijet production at hadron colliders. The top-sector topology contains an…
