“…The scale factors are close to unity (0.89-1.06, with uncertainties between 0.03 and 0.06) in the lowest p T bin (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30), and decrease to between 0.5 and 0.6 at high p T [Oð100 GeVÞ].…”

“…Results are interpreted in terms of modelindependent limits on the event yields from new physics processes leading to the given signature, as well as in a variety of specific SUSY scenarios. These scenarios include RPV and RPC simplified models, which describe the interactions of a minimal set of particles, as well as models with general gauge-mediated SUSY breaking (GGM) [18,19], which is a generalization of gauge-mediated SUSY breaking theories (GMSB) [20][21][22][23][24][25] where the parametrization does not depend on the details of the SUSY breaking mechanism. This analysis updates and extends results presented previously by ATLAS [26].…”

Search for supersymmetry in events with four or more leptons ins=8 TeVppcollisions with the ATLAS detector

Results from a search for supersymmetry in events with four or more leptons including electrons, muons and taus are presented. The analysis uses a data sample corresponding to 20.3 fb −1 of proton-proton collisions delivered by the Large Hadron Collider at ffiffi ffi s p ¼ 8 TeV and recorded by the ATLAS detector.Signal regions are designed to target supersymmetric scenarios that can be either enriched in or depleted of events involving the production of a Z boson. No significant deviations are observed in data from standard model predictions and results are used to set upper limits on the event yields from processes beyond the standard model. Exclusion limits at the 95% confidence level on the masses of relevant supersymmetric particles are obtained. In R-parity-violating simplified models with decays of the lightest supersymmetric particle to electrons and muons, limits of 1350 and 750 GeV are placed on gluino and chargino masses, respectively. In R-parity-conserving simplified models with heavy neutralinos decaying to a massless lightest supersymmetric particle, heavy neutralino masses up to 620 GeV are excluded. Limits are also placed on other supersymmetric scenarios.

After an introduction recalling the theoretical motivation for low energy (100 GeV to TeV scale) supersymmetry, this review describes the theory and experimental implications of the soft supersymmetry-breaking Lagrangian of the general minimal supersymmetric standard model (MSSM). Extensions to include neutrino masses and nonminimal theories are also discussed. Topics covered include models of supersymmetry breaking, phenomenological constraints from electroweak symmetry breaking, flavor/CP violation, collider searches, and cosmological constraints including dark matter and implications for baryogenesis and inflation.

“…Moreover, unless both N 1 and N 2 are even, the R symmetry becomes trivial. 5 Thus, we expec that gaugino masses are generated by radiative corrections [21,22,23] for the entire gauge group G except for the diagonal U (1), for which q 12 , q 21 are neutral.…”

Landscape of supersymmetry breaking vacua in geometrically realized gauge theories

We study vacuum structure of N = 1 supersymmetric quiver gauge theories which can be realized geometrically by D brane probes wrapping cycles of local Calabi-Yau threefolds. In particular, we show that the A 2 quiver theory with gauge group U (N 1 ) × U (N 2 ) with 1 2 N 1 < N 2 < 2 3 N 1 has a regime with an infrared free description that is partially magnetic and partially electric. Using this dual description, we show that the model has a landscape of inequivalent meta-stable vacua where supersymmetry is dynamically broken and all the moduli are stabilized. Each vacuum has distinct unbroken gauge symmetry. The gaugino masses are generated by radiative corrections, and we are left with the bosonic pure Yang-Mills theory in the infrared. We also identify the supersymmetric vacua in this model using their infrared free descriptions and show that the decay rates of the supersymmetry breaking vacua can be made parametrically small.
