Differential equations, recurrence relations, and quadratic constraints for L-loop two-point massive tadpoles and propagators.
Abstract We consider L-loop two-point tadpole (watermelon) integral with arbitrary masses, regularized both dimensionally and analytically. We derive differential equation system and recurrence relations (shifts of dimension and denominator powers). Since the L-loop sunrise integral corresponds to t...
