Description
Results are presented from a search for the electroweak production of
supersymmetric particles in pp collisions in final states with two τ
leptons. The data sample corresponds to an integrated luminosity between
18.1 fb-1 and 19.6 fb-1 depending on the final
state of τ lepton decays, at √{s}=8 TeV, collected by the CMS
experiment at the LHC. The observed event yields in the signal regions
are consistent with the expected standard model backgrounds. The results
are interpreted using simplified models describing the pair production
and decays of charginos or τ sleptons. For models describing the
pair production of the lightest chargino, exclusion regions are obtained
in the plane of chargino mass vs. neutralino mass under the following
assumptions: the chargino decays into third-generation sleptons, which
are taken to be the lightest sleptons, and the sleptons masses lie
midway between those of the chargino and the neutralino. Chargino masses
below 420 GeV are excluded at a 95% confidence level in the limit of a
massless neutralino, and for neutralino masses up to 100 GeV, chargino
masses up to 325 GeV are excluded at 95% confidence level. Constraints
are also placed on the cross section for pair production of τ
sleptons as a function of mass, assuming a massless neutralino. [Figure
