Abstract

We discuss possible ways to observationally detect the superdense cosmic objects composed of hypothetical subconstituent fermions beneath the quark/lepton level, recently proposed by us. The characteristic mass and size of such objects depend on the compositeness scale, and their huge density cannot arise within a context of quarks and leptons alone. Their eventual observation would therefore be a direct vindication of physics beyond the standard model of particle physics, possibly far beyond the reach of the Large Hadron Collider (LHC), in a relatively simple and inexpensive manner. If relic objects of this type exist, they can possibly be detected by present and future x-ray observatories, high-frequency gravitational wave detectors, and seismological detectors. To have a realistic detection rate, i.e., to be observable, they must necessarily constitute a significant fraction of cold dark matter.

  29. The observed counts in a gamma-ray detector corresponds to the energy loss spectrum, which is created by the gamma photons as they interact with the medium in the detector, e.g., sodium iodide or germanium. Consequently, it is not certain that the energy of a particular count equals the energy of an incident photon. The spectrum of the light entering the detector can therefore not be deduced from data. Instead, model spectra are used in conjunction with data to calculate the probability that the physical spectrum is/is not explained by a particular model. In this procedure, details about the detector response functions and the original data are needed. We were unable to obtain this information for the detector aboard Ginga and for GRB 880205. A formal detailed comparison with femtolensing spectra has therefore not been done.
