---++ !SUSY Cross Sections for 13, 14, 33 and 100 !TeV pp Collisions

---+++ Abstract

We summarise the status of the cross section predictions for various supersymmetric processes in pp
collisions at sqrt(s)=13, 14, 33 and 100 !TeV. This document is based on the agreement between the ATLAS and CMS
collaborations, as well as with the LPCC !SUSY cross section working group. Calculations including
the resummation of soft gluon emission at the next-to-leading logarithmic accuracy are used whenever
available. In all other cases we rely on the next-to-leading order in the strong coupling constant. These
cross sections and their uncertainties are provided for various scale and PDF choices.

---++ !SUSY Cross Sections for 7 !TeV pp Collisions

---+++ Abstract
We summarise the status of the cross section predictions for various supersymmetric processes in pp
collisions at sqrt(s)=7 !TeV. This document is based on the agreement between the ATLAS and CMS
collaborations, as well as with the LPCC !SUSY cross section working group. Calculations including
the resummation of soft gluon emission at the next-to-leading logarithmic accuracy are used whenever
available. In all other cases we rely on the next-to-leading order in the strong coupling constant. These
cross sections and their uncertainties are provided for various scale and !PDF choices.

---+++ Cross sections for various subprocesses

*Important notice:* ATLAS and CMS used the same CMSSM  tanbeta grid but the program performing the Renormalisation Group Equations is different (ATLAS is using ISAJET whereas CMS is using SOFTSUSY). These different programs lead to differences in mass at the 7 !TeV scale. In particular, for the same starting m0 and m1/2 combination, the sparticle masses used in ATLAS are usually slightly higher than the ones used in CMS case. This effect has two effects which partially cancel each other: on the one hand, CMS cross sections are higher than those of ATLAS but, on the other hand, ATLAS scenarios tend to have slightly harder jet !pT spectrum, leading to a slightly higher acceptance in most of the analyses. The SUSY Working Groups of the two collaborations agreed to use the same generator for analyses using 8 !TeV centre-of-mass energy.
