“…It is important to note, however, that in the interpretation of their experimental results, both the ATLAS and CMS collaborations typically use a very special theoretical model, the so-called Constrained Minimal Supersymmetric Standard Model (CMSSM), which is characterized by just four-and-a-half parameters [5][6][7][8][9][10][11]: a universal scalar mass m 0 , gaugino mass m 1/2 and trilinear coupling A 0 defined at the GUT scale M GUT ∼ 10 16 GeV, plus tan β and sign(µ). The simplifying assumption of universality at the GUT scale makes the model very predictive and a convenient showcase for SUSY phenomenology.…”

We interpret within the phenomenological MSSM (pMSSM) the results of SUSY searches published by the CMS collaboration based on the first ∼1 fb −1 of data taken during the 2011 LHC run at 7 TeV. The pMSSM is a 19-dimensional parametrization of the MSSM that captures most of its phenomenological features. It encompasses, and goes beyond, a broad range of more constrained SUSY models. Performing a global Bayesian analysis, we obtain posterior probability densities of parameters, masses and derived observables. In contrast to constraints derived for particular SUSY breaking schemes, such as the CMSSM, our results provide more generic conclusions on how the current data constrain the MSSM.

“…As such findings of the experiments were presented in the form of model-independent non-SM cross section limits and interpretations showing exclusion regions within specific models of SUSY such as the constrained version of the R-parity conserving minimal supersymmetric standard model (MSSM) called CMSSM/mSUGRA, particular SUSY breaking schemes (for a review see e.g. [5]) or simplified models [6] of SUSY scenarios.…”

The ATLAS collaboration published supersymmetry limits based on up to about 4.7 fb −1 data collected over the year 2011 from LHC runs at 7 TeV. These were mainly interpreted within restricted, particular or simplified models for supersymmetry breaking schemes or scenarios. The pMSSM is an alternative and more generic supersymmetry framework which captures broader phenomenological features. Searching for more generic conclusions from the supersymmetry limits interpretation, we update a Bayesian global fit of the pMSSM to pre-LHC data using the LHC-7 limits. The posterior distributions show the most up to date features, revealing allowed versus excluded regions in sparticle mass planes within the MSSM. *

“…In supergravity theories [2][3][4][5], over most of the parameter space of models consistent with the radiative breaking of the electroweak symmetry, the lightest neutralino is found to be the lightest supersymmetric particle, and this, along with R-parity (defined as R = (−1) 2S+3(B−L) , where S, B and L stand for the spin, baryon number and lepton number, respectively) and charge neutrality allows for the lightest neutralino to be a promising candidate for cold dark matter as suggested in [6].…”

Abstract:We investigate the connection between the conservation of R-parity in supersymmetry and the Stueckelberg mechanism for the mass generation of the B − L vector gauge boson. It is shown that with universal boundary conditions for soft terms of sfermions in each family at the high scale and with the Stueckelberg mechanism for generating mass for the B − L gauge boson present in the theory, electric charge conservation guarantees the conservation of R-parity in the minimal B − L extended supersymmetric standard model. We also discuss non-minimal extensions. This includes extensions where the gauge symmetries arise with an additional U(1) B−L ⊗ U(1) X , where U(1) X is a hidden sector gauge group. In this case the presence of the additional U(1) X allows for a Z ′ gauge boson mass with B − L interactions to lie in the sub-TeV region overcoming the multi-TeV LEP constraints. The possible tests of the models at colliders and in dark matter experiments are analyzed including signals of a low mass Z ′ resonance and the production of spin zero bosons and their decays into two photons. In this model two types of dark matter candidates emerge which are Majorana and Dirac particles. Predictions are made for a possible simultaneous observation of new physics events in dark matter experiments and at the LHC.
