A brief review of recent results on asymptotic expansions of Feynman integrals on the mass shell in momenta and masses and their application to 2-loop calculations is presented.
متن کاملThree-loop on-shell Feynman integrals with two masses
All three-loop on-shell QCD Feynman integrals with two masses can be reduced to 27 master integrals. Here we calculate these master integrals, expanded in ε, both exactly in the mass ratio and as series in limiting cases.
متن کاملSeries expansion of Wiener integrals via block pulse functions
In this paper, a suitable numerical method based on block pulse functions is introduced to approximate the Wiener integrals which the exact solution of them is not exist or it may be so hard to find their exact solutions. Furthermore, the error analysis of this method is given. Some numerical examples are provided which show that the approximation method has a good degree of accuracy. The main ...

متن کاملEuler-Maclaurin expansions for integrals with arbitrary algebraic endpoint singularities
In this paper, we provide the Euler–Maclaurin expansions for (offset) trapezoidal rule approximations of the divergent finite-range integrals ∫ b a f(x) dx, where f ∈ C ∞(a, b) but can have arbitrary algebraic singularities at one or both endpoints. We assume that f(x) has asymptotic expansions of the general forms f(x) ∼ K (x− a)−1 + ∞ ∑ s=0 cs(x− a)s as x → a+, f(x) ∼ L (b− x)−1 + ∞ ∑ s=0 ds(...
