چکیده
For loop integrals the standard method is reduction. A well-known reduction for one-loop Passarino-Veltman (PV) Inspired by recent paper [B. Feng, T. Li, and X. J. High Energy Phys. 09 (2021) 081.] where tadpole coefficients have been solved, in this we show same technique can be used to give a complete integral any integrals. The differential operator an alternative version of PV-reduction method. Using method, analytic expressions all master given algebraic recurrence relation easily. We demonstrate our explicitly with several examples.

Algorithm FIRE — Feynman Integral REduction
The recently developed algorithm FIRE performs the reduction of Feynman integrals to master integrals. It is based on a number of strategies, such as applying the Laporta algorithm, the s-bases algorithm, region-bases and integrating explicitly over loop momenta when possible. Currently it is being used in complicated three-loop calculations. Supported by RFBR grant 08-02-01451-a and DFG throug...
متن کاملReduze - Feynman integral reduction in C++
Reduze is a computer program for reducing Feynman integrals to master integrals employing a Laporta algorithm. The program is written in C++ and uses classes provided by the GiNaC library to perform the simplifications of the algebraic prefactors in the system of equations. Reduze offers the possibility to run reductions in parallel. Catalogue identifier: AEGEv10ProgramsummaryURL : http : //cpc...
متن کاملSome variations of the reduction of one-loop Feynman tensor integrals
We present a new algorithm for the reduction of one-loop tensor Feynman integrals with n ≤ 4 external legs to scalar Feynman integrals ID n with n = 3,4 legs in D dimensions, where D = d +2l with integer l ≥ 0 and generic dimension d = 4− 2ε , thus avoiding the appearance of inverse Gram determinants ()4. As long as ()4 6= 0, the integrals ID 3,4 with D > d may be further expressed by the usual...
متن کاملReduction method for dimensionally regulated one-loop N-point Feynman integrals
We present a systematic method for reducing an arbitrary one−loop N(≥ 5)−point massless Feynman integral with generic 4−dimensional momenta to a set comprised of eight fundamental scalar integrals: six box integrals in D = 6, a triangle integral in D = 4, and a general two−point integral in D = 4 + 2ε space time dimensions. All IR divergences present in the original integral are contained in th...
متن کاملDifferential reduction of generalized hypergeometric functions in application to Feynman diagrams: One-variable case
The differential reduction algorithm which allow one to express generalized hypergeometric functions with arbitrary values of parameters in terms of functions with fixed values of parameters differing from the original ones by integers is discussed in a context of evaluation of Feynman diagrams. Where it is possible we make a comparison between our results and ones based on a standard technique...
