Testing the correlation of ultrahigh energy cosmic rays with high redshiftsources - art. no. 081302

We study the correlation between compact radio quasars or 3EG gamma-ray bla zars and the arrival direction of cosmic rays above 10(19) eV using an upda ted list of air shower detections. Our Monte Carlo simulations reveal no si gnificant correlations above random results, and some previous positive res ults appear to be an effect of the small sample size. Consequently, there i s no evidence for ultrahigh energy cosmic ray primaries being new particles or particles with new interactions beyond the electroweak scale, produced in high-redshift active galactic nuclei.
