Searches for New Physics at HERA

Recent results on physics beyond the standard model from ZEUS and H1 experiments are presented, in particlular results on single top and stop production, new currents modifying Standard Model (SM) Deep Inelastic Scattering (DIS) cross sections (eg. RH currents), low SM cross section processes and many possible final states, eg. multilepton and isolated lepton production, single top production, stop production, etc. The data samples were obtained during the older HERA runs as well as during the upgraded HERA‐II phase started in 2003. In general the obtained results agree with standard model predictions. New particles have not been seen. H1 has seen an excess of di‐ and tri‐lepton events in the e+p channel.
