Small-threshold Behaviour of Two-loop Self-energy Diagrams: Some Special Cases * †
An algorithm to construct analytic approximations to two-loop diagrams describing their behaviour at small non-zero thresholds is discussed. For some special cases (involving two different-scale mass parameters), several terms of the expansion are obtained. ∗ Presented at QCD and QED in Higher Order, 1996 Zeuthen Workshop on Elementary Particle Theory, Rheinsberg, April 21–26, 1996, to appear i...
متن کاملTwo-loop self-energy diagrams worked out with NDIM
In this work we calculate two two-loop massless Feynman integrals pertaining to self-energy diagrams using NDIM (Negative Dimensional Integration Method). We show that the answer we get is 36-fold degenerate. We then consider special cases of exponents for propagators and the outcoming results compared with known ones obtained via traditional methods. PACS numbers: 02.90+p, 03.70+k, 12.38.Bx Sh...
متن کاملThreshold behavior of Feynman diagrams : the master two - loop
An asymptotic expansion of the two-loop two-point \master" diagram with two masses m and M, on the mass shell Q 2 = M 2 , is presented. The treatment of the non-analytical terms arising in the expansion around the branching point is discussed. Some details of the calculation of a new class of two-loop integrals are given.
متن کاملThreshold behavior of Feynman diagrams: the master two-loop propagator
An asymptotic expansion of the two-loop two-point “master” diagram with two masses m and M , on the mass shell Q = M, is presented. The treatment of the non-analytical terms arising in the expansion around the branching point is discussed. Some details of the calculation of a new class of two-loop integrals are given.

متن کاملDifferential equations and high-energy expansion of two–loop diagrams in D dimensions
New method of calculation of master integrals using differential equations and asymptotical expansion is presented. This method leads to the results exact in space-time dimension D having the form of the convergent power series. As an application of this method, we calculate the two–loop master integral for ”crossed–triangle” topology which was previously known only up to O(ǫ) order. The case w...
