Abstract:
An emulsion chamber of 13 tons Pb was exposed on Mt. Kanbala (5500 m abovesea level) of Tibet. A very interesting ultra-high energy event with total observedenergy ΣEΥ=445 TeV was obtained. The profile of the event is characterised by twogroups of high energy showers, separated clearly from each other. Preliminary analysisshows that the particles giving rise to these two shower groups have extraordina-rily large transverse momenta. This predicts the possible existence of a new mechanismin ultra-high energy nuclear interactions, which has certain characteristics differentfrom those predicted by the H-quantum and SH-quantum models.
