Search for SUSY Light sparticles in Vector Boson Fusion processes with two like sign Taus — •Daniele Marconi, Denis Rathjens, Christian Sander, and Lukas Vanelderen — Universität Hamburg
The LHC has placed bounds on the masses of gluino and 1st/2nd generation squarks of the order of 1 TeV. On the other hand, the bounds on the SUSY partners of electroweak gauge bosons and leptons are less stringent. These bounds, combined with the cosmologically favoured stau-neutralino coannihilation region, points to SUSY models with light 3rd generation particles and light charginos/neutralinos. The production of sleptons and EWKinos via Vector Boson Fusion (VBF) offers a promising avenue to study the non colored sectors of SUSY. Taking advantage of kinematic properties of the backward-forward jets, produced in VBF processes it is possible to reduce the background of Standard Model processes with rather loose selection of the "central" part of the event
We present a search for EWKinos and sleptons produced in VBF processes in same sign taus final states. The data sample corresponds to an integrated luminosity of 20 fb−1 of pp collisions at √s = 8 TeV collected with the CMS detector.
