Abstract

Searches for Physics beyond the Standard Model have entered an exciting new phase: the complete HERA data samples obtained until the end of operations in the Summer of 2007 are now available for analysis. ZEUS and H1 have each collected about 0.5 fb^{-1} of lepton proton data, distributed over electron and positron running, and over different lepton beam polarisations. At the same time the Fermilab Tevatron proton-antiproton collider is accumulating data at unprecedented rates, with current analyses based on up to 3 fb^{-1}. The Tevatron experiments DZERO and CDF have each already recorded over 4 fb^{-1} (Fall 2008), and are aiming for a total of 8 fb^{-1} of antiproton-proton collisions at 2 TeV center-of-mass energy for Tevatron Run II. I am presenting recent updates (from the last 12 months) on searches, grouped loosely into three classes: well-established `traditional' searches, mostly for very specific signatures and models, more recent and/or more generalized searches for broader classes of phenomena, and newer searches that strive to be model-independent.
