Benchmark models, planes, lines and points for future SUSY searches at the LHC

Abstract

We define benchmark models for SUSY searches at the LHC, including the CMSSM, NUHM, mGMSB, mAMSB, MM-AMSB and p19MSSM, as well as models with R-parity violation and the NMSSM. Within the parameter spaces of these models, we propose benchmark subspaces, including planes, lines and points along them. The planes may be useful for presenting results of the experimental searches in different SUSY scenarios, while the specific benchmark points may serve for more detailed detector performance tests and comparisons. We also describe algorithms for defining suitable benchmark points along the proposed lines in the parameter spaces, and we define a few benchmark points motivated by recent fits to existing experimental data.

Lepton flavour violation: physics potential of a Linear Collider

“…with a gluino mass just above the LHC exclusion bound) and the other with a comparatively heavier one (associated with mg = 2 TeV). The points with low tan β have a phenomenology similar to that of the points along the 10.1.n slope of the recent LHC benchmark proposal [119]. Moreover, the relatively lowvalues of m 0 (when compared to M 1/2 ) lead to a lighter slepton spectrum, that can be easily produced at a LC (while avoiding the LHC bounds on the strongly interacting sector).…”

Gaugino production in proton-proton collisions at a center-of-mass energy of 8 TeV

“…Selection of benchmark points on the cMSSM model line 10.1 of ref. [6] with tan β = 10, A 0 = 0 GeV, and m 0 = 0.25 × m 1/2 . The points are spaced in steps of ∆m 1/2 = 50 GeV, and the gluino and average squark masses are rounded to 5 GeV accuracy.…”

“…[6] with a large value of tan β = 40 and a large negative value of the universal scalar trilinear coupling A 0 = −500 GeV. We retain the high values of the universal scalar and gaugino masses that have driven the choice of our second scenario and therefore adopt the point 31 of the LPCC numbering scheme as our third benchmark point.…”
