A general algorithm to build real-radiation antenna functions for higher-order calculations

چکیده

A bstract The antenna subtraction method has been successfully applied to a wide range of processes relevant for the Large Hadron Collider at next-to-next-to-leading order in α s (NNLO). We propose an algorithm building functions any number real emissions from identified pair hard radiator partons directly specified list unresolved limits. use explicitly build all single- and double-real QCD compare them previous functions, which were extracted matrix elements. improved should be more easily applicable NNLO terms. Finally, we match integration over final-final phase space incarnation, serving as independent check on our results.

Benders decomposition algorithm for a green closed-loop supply chain under a build-to-order environment

Nowadays, researches pay more attention to environmental concerns consisted of various communities. This study proposes a multi-echelon, multi-period closed-loop supply chain (CLSC). A comprehensive model considers the selection of selection of technology and environmental effects. The supply chain is under a build-to-order (BTO) environment. So, there is not a final product inventory. Also, th...

Higher Order Functions Considered Unnecessary for Higher Order Programming

It is often claimed that the essence of functional programming is the use of functions as values, i.e., of higher order functions, and many interesting examples have been given showing the power of this approach. Unfortunately, the logic of higher order functions is diicult, and in particular, higher order uniication is undecidable. Moreover (and closely related), higher order expressions are n...

Higher-Order Functions for Parsing

In combinator parsing , the text of parsers resembles BNF notation. We present the basic method, and a number of extensions. We address the special problems presented by white– space, and parsers with separate lexical and syntactic phases. In particular, a combining form for handling the “offside rule” is given. Other extensions to the basic method include an “into” combining form with many use...
