lcarpino / ARES

Mathematica package for resumming Sudakov logarithms in QCD

ARES

ARES is a Mathematica package for resumming event-shape variables at next-to-next-to-leading-logarithmic accuracy.

Download

You can obtain ARES releases directly from the github repository:

https://github.com/lcarpino/ARES/releases

For the latest development version you can clone the master:

git clone https://github.com/lcarpino/ARES.git

For the latest tag:

git tag -l
git checkout tags/tag_name

Installation

To install, simply copy the ARES directory into

/home/$USER/.Mathematica/Applications

Alternatively one may link to the ARES directory instead

ln -s ARES /home/$USER/.Mathematica/Applications/ARES

Usage

To use ARES in a Mathematica notebook or package include

<<ARES`

An example of standard usage

(* Load the ARES package *)
<<ARES`

(* declare an observable of interest, the D-parameter here *)
dpar = BuildObservable["DParameter"];

(* Resum the D-parameter for the event configuration given by {xq, xqb}, 
   where the observable takes the value v *)
Resum[{xq, xqb}, Log[1/v], dpar, {"Order" -> "NNLL"}]
