Counting master integrals: Integration-by-parts procedure with effective mass

We show that the new relation between master integrals recently obtained in M.Yu. Kalmykov and B.A. Kniehl (2011) [1] can be reproduced using the integration-by-parts technique implemented with an effective mass. In fact, this relation is recovered as a special case of a whole family of new relation...

Zusammenfassung:We show that the new relation between master integrals recently obtained in M.Yu. Kalmykov and B.A. Kniehl (2011) [1] can be reproduced using the integration-by-parts technique implemented with an effective mass. In fact, this relation is recovered as a special case of a whole family of new relations between master integrals.
