Description
We present our analytic calculation of the master integrals for gg->gh at 2-loops with internal top quarks, considering the planar elliptic family. We bring the system of differential equations into the epsilon-factorised form using transformations involving elliptic integrals. We present our approach to find a suitable variable change from the kinematic space to the punctured torus. Using this, we write the differential equations in terms of Kronecker-Eisenstein forms and the resulting iterated integrals in terms of elliptic Multiple Polylogarithms (eMPLs).
