Multiloop corrections for collider processes using auxiliary mass flow

With a key improvement, the auxiliary mass flow method is now able to compute Feynman integrals encountered in cutting-edge collider processes. We have successfully applied it some involved two-loop electroweak corrections ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}HZ$, QCD $3j$, $W/Z/H+2j$, $t\overline{t}H$ and $4j$ production at hadron colliders, three-loop $t\overline{t}$ all of which are crucial for precision frontier physics following decade. Our results important building blocks benchmarks future studies these
