Search for Simultaneous Parallel EAS Events in Long Baseline EAS Arrays with LAAS

The probabilities of observing simultaneous parallel extensive air showers (EAS) produced by nuclear fragments of cosmic ray nuclei which disintegrated in collisions with solar photons are calculated as function of longitudinal angle from the sun direction. The mean separation distances of such events are also numerically simulated by analyzing fragment trajectories of nuclei in the solar magnetic field. We report on candidates of events observed at both small and long baseline array combinations in LAAS in this paper.
