We report the observation of five events in which a missing transverse energy larger than 40 GeV is associated with a narrow hadronic jet and of two similar events with a neutral electromagnetic cluster (either one or more closely spaced photons). We cannot find an explanation for such events in terms of backgrounds or within the expectations of the Standard Model. We report here the observation of a novel type of 1 Present address:doi:10.1016/0370-2693(84)90046-7 fatcat:ny33fd3s4fad3ga6dfetyw4zly
