### Event details

The differential equation method has gained much momentum in recent years for the computation of 2- and higher-loop Feynman integrals and understanding their geometrical aspects. In my talk, after summarising the method of differential equations and its technical details, I will represent its application to compute the 2-loop master integrals keeping the full mass dependence that appear in $O(\alpha \alpha_s)$ corrections to $H > ZZ*$ decay (arxiv: 2205.06339). I will also discuss the difficulties we encounter due to the presence of multiple mass scales. Finally, I will represent the results of master integrals obtained in terms of Chen-iterated integrals with dlog-one forms.

### About Particle Physics Theory seminars

The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
