Towards analytic structure of Feynman parameter integrals with rational curves
Abstract We propose a strategy to study the analytic structure of Feynman parameter integrals where singularities of the integrand consist of rational irreducible components. At the core of this strategy is the identification of a selected stratum of discontinuities induced from the integral, togeth...
