AlbaNova and Nordita Colloquium
Glennys Farrar (New York University)
FR4 Oskar Kleins Auditorium
Thursday 05 December
15:00 - 16:00
I will discuss the physics of UHECR air showers and report how present models tuned at accelerator energies, fail to describe Auger data above E_CM ~ 100 TeV. Possibilities for new physical phenomena which could explain these observations will be described. More detailed studies of UHECR air showers can discriminate between models, as will be explained.
