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.
