Search for R -parity violating supersymmetry with displaced vertices in proton-proton collisions at s =8 TeV
Results are reported from a search for R-parity violating supersymmetry in proton-proton collision events collected by the CMS experiment at a center-of-mass energy of ffiffi s p ¼ 8 TeV. The data sample corresponds to an integrated luminosity of 17.6 fb−1. This search assumes a minimal flavor vi...

| description | Results are reported from a search for R-parity violating supersymmetry in proton-proton collision
events collected by the CMS experiment at a center-of-mass energy of ffiffi
s p ¼ 8 TeV. The data sample
corresponds to an integrated luminosity of 17.6 fb−1. This search assumes a minimal flavor violating model
in which the lightest supersymmetric particle is a long-lived neutralino or gluino, leading to a signal with
jets emanating from displaced vertices. In a sample of events with two displaced vertices, no excess yield
above the expectation from standard model processes is observed, and limits are placed on the pair
production cross section as a function of mass and lifetime of the neutralino or gluino. At 95% confidence
level, the analysis excludes cross sections above approximately 1 fb for neutralinos or gluinos with mass
between 400 and 1500 GeV and mean proper decay length between 1 and 30 mm. Gluino masses are
excluded below 1 and 1.3 TeV for mean proper decay lengths of 300 μm and 1 mm, respectively, and below
1.4 TeV for the range 2–30 mm. The results are also applicable to other models in which long-lived
particles decay into multijet final states. |
