Description
I will present the method of tropical Monte Carlo integration for scalar Feynman integrals in the software feyntrop. In order to apply this approach in the physical regime, I introduce a parametric representation of Feynman integrals that implements the causal $i\varepsilon$ prescription concretely while retaining projective invariance. feyntrop can efficiently evaluate dimensionally regulated, quasi-finite Feynman integrals, with not too exceptional kinematics in the physical regime, with a relatively large number of propagators and with arbitrarily many kinematic scales. I will review some of the mathematical ingredients for tropical Monte Carlo integration and discuss new upgrades being made to feyntrop.
