โœฆ Synopsis

Recent studies of cosmic-ray energy spectrum in the region above 5 ร— 10 19 eV, did not confirm the existence of the predicted cutoff associated with the Greizen-Zatcepin-Kuzmin (GZK) effect. The explanation of this contradiction has generated a number of rather exotic assumptions. Below, we present the results obtained with different experimental arrays, which show that a possible reason for the appearance of events with an energy exceeding 5 ร— 10 19 eV can be the long-flying hadronic component formed in interactions of high-energy particles in the atmosphere.

A class of models of quantized, massless Bose fields, called the generalized spinboson model (A. Arai and M. Hirokawa, J. Funct. Anal. 151 (1997), 455 503) is considered. Theorems on the absence of ground states and the other eigenvectors of the model without infrared cutoff (but with ultraviolet cu
