XLOOPS: Explicit Loop Specialization
Hardware specialization is becoming an increasingly common technique to enable improved performance and efficiency in spite of the diminished benefits of technology scaling. Meanwhile, computer architects have long realized the importance of focusing on the key loops that often dominate application performance. These two trends have led to a diverse array of loop-level specialized hardware, suc...
متن کاملSFOLD - A program package for calculating two-body sfermion decays at full one-loop level in the MSSM
SFOLD (Sfermion Full One Loop Decays) is a Fortran program package for calculating all sfermion two-body decay widths and the corresponding branching ratios at full one-loop level within the MSSM. The package adopts the SUSY Parameter Analysis convention and supports the SUSY Les Houches Accord input and output format. With the SFOLD package we found nonnegligible electroweak corrections in bos...
متن کاملGenerating and Calculating One-loop Feynman Diagrams with FeynArts, FormCalc, and LoopTools
A set of programs is presented for automatically generating and calculating Feynman diagrams. Diagrams are generated with FeynArts, then algebraically simplified using a combination of Mathematica and FORM implemented in the package FormCalc, and finally evaluated numerically using the LoopTools package. FormCalc works either in dimensional regularization or in constrained differential renormal...
متن کاملNGluon: A package to calculate one-loop multi-gluon amplitudes
We present a computer library for the numerical evaluation of colourordered n-gluon amplitudes at one-loop order in pure Yang-Mills theory. The library uses the recently developed technique of generalised unitarity. Running in double precision the library yields reliable results for up to 14 gluons with only a small fraction of events requiring a re-evaluation using extended floating point arit...
متن کاملAlgorithmic Calculation of Two-loop Feynman Diagrams *
In a recent paper [1] a new powerful method to calculate Feynman diagrams was proposed. It consists in setting up a Taylor series expansion in the external momenta squared. The Taylor coefficients are obtained from the original diagram by differentiation and putting the external momenta equal to zero. It was demonstrated that by a certain conformal mapping and subsequent resummation by means of...
