Description
I will present a new computer program, feyntrop, which uses the tropical Monte Carlo approach to evaluate Feynman integrals numerically.
In order to apply this approach for physical kinematics, we introduce a new parametric representation of Feynman integrals that implements the causal iε prescription concretely while retaining projective invariance. feyntrop can efficiently evaluate dimensionally regulated, quasi-finite Feynman integrals, with not too exceptional kinematics in the physical region, with a relatively large number of propagators and with arbitrarily many kinematic scales. I will provide the necessary mathematical background and discuss many explicit examples of evaluated Feynman integrals.
