Exotic Physics at HERA

Abstract

A search for excited neutrinos, the analysis of multi-lepton final states, a search for doubly charged Higgs production and a general search for high-Pt phenomena at HERA are reported. The searches use data samples of ep collisions with a centre-of-mass energy sqrt(s)=320 GeV collected by the H1 and ZEUS experiments at HERA in the years 1994-2005 with integrated luminosities up to 296 pb^-1. Overall no significant deviations of the experimental observations from the Standard Model (SM) expectation are found.
