Results of searches for Leptoquarks, Isolated Leptons and Multileptons with the H1
and ZEUS experiments in ep collisions at HERA are presented. The analyses use the
full statistics of HERA high energy running which ended in March 2007. Combined
results of both experiments based on a total integrated luminosity of about 1 fb-1
are also shown.

We report on a search for scalar top quark pair production in the lepton+jets
channel. Just like Standard Model top quarks, scalar top quarks are produced in
pairs in proton-antiproton collisions. One of the preferred scenarios is for the
scalar top to decay to a b-quark and a chargino, with the chargino
subsequently decaying into a real or virtual W boson and a neutralino. The...

A search for associated production of charginos and neutralinos is performed
using data recorded with the D0 detector at a p-pbar center-of-mass energy of
1.96 TeV at the Fermilab Tevatron Collider. This analysis considers final states
with missing transverse energy and three leptons, including hadronic decays of
tau leptons. With more than 2fb-1 of data recorded by the D0 experiment,...

We present the results of a search for associated production of the lightest
chargino and next-to-lightest neutralino using 1fb-1 of sqrt s = 1.96 TeV ppbar
data collected with the CDF detector at the Tevatron. We combine the results of
several multi-lepton final states to set upper limits on the cross section
times branching ratio for chargino-neutralino production as a function...

he direct production of neutralino-chargino pairs in the mSUGRA scenario with decays
to a pure trilepton final state has a significant cross section at low neutralino
masses and is a viable SUSY discovery channel at the LHC. The main Standard Model
background are from Z/gamma + jets, WZ/gamma and ttbar channels where dileptons
appear from Z decays and a third lepton is coming either from...
