CALICO: Computing Annihilators from Linear Identities Constraining (differential) Operators
Giuseppe Bertolini, Gaia Fontana, Tiziano Peraro
We elaborate on the method of parametric annihilators for deriving integral relations. Parametric annihilators are differential operators that annihilate multivalued integration ke…

Reduction to master integrals and transverse integration identities
Vsevolod Chestnov, Gaia Fontana, Tiziano Peraro
The reduction of Feynman integrals to a basis of linearly independent master integrals is a pivotal step in loop calculations, but also one of the main bottlenecks. In this paper,…
