An excess of events at large Q2 with a positron in the final state has been observed at HERA which, if confirmed, would be a signal of new physics. It is not clear at present if a signal of comparable rate is also seen in the charged…

We present the most recent results on searches for squarks and gluinos in ppbar collisions at sqrt(s)=1.96 TeV, in events with large missing transverse energy, leptons and multiple jets in the final state, based on 1.8 to 2.8 fb-1 of data…
Highlights of the search for SUSY at ATLAS are presented emphasising on the variety of searches that were performed in the LHC Run I in p-p collisions at a centre of mass of 7 TeV and 8TeV. Searches for squars, gluinos, third generation…
Attempts to understand the recent observation of an excess of events in the neutral and charged current channels at high$-Q^2$ at HERA has provided an excellent example of how experiments at both low and high energies can be used to…
Formation of the $s$-channel slepton resonances at LEP2 or Tevatron at current energies is an exciting possibility in R-parity violating SUSY models. Existing LEP2 and Tevatron data can be exploited to look for sleptons, or to derive bounds…
