Powheg tips and tricks:

get a fresh version of the package svn checkout --username anonymous --password anonymous svn://powhegbox.mib.infn.it/trunk/POWHEG-BOX

change to the process folder of the kind of process you want to generate cd POWHEG-BOX/Dijet/

this is a better manual than the one online – this is the one I am working from with these instructions open Docs/manual-BOX-Dijet.pdf

compile make pwhg_main

change to the run directory cd testrun-lhc/

open the input file emacs powheg.input

run the programme ../pwhg_main

you will notice that it is SLOW! It will take about three hours to run.`

IGNORE THIS FOR NOW!

Step 2: add fastjet.

Download fastjet: laptop->curl -O http://fastjet.fr/repo/fastjet-3.2.1.tar.gz unpack the tarball: tar -zxvf fastjet-3.2.1.tar.gz change to the fastjet folder cd fastjet-3.2.1 configure fastjet ./configure --prefix=/usr/local/fastjet-install --enable-d0runiicone compile make make check make install

Now lets go back to our POWHEG workspace cd ~/POWHEG-BOX/Dijet Open the makefile emacs Makefile Turn on the default (fastjet) analysis switch ANALYSIS=default Then ctrl-x-s to save, and ctrl-x-c to close make pwhg_main
