Description
Energy dependence of proton-nucleus reaction cross section at very high energy is discussed. It is stressed that depending on the gluon distribution near the nuclear surface, proton-nucleus total cross section increases much more rapidly compared to the usual Glauber independent nucleon estimate. The recent observation of Xmax smaller than the expected value at UHECR domain can be an indication for such a mechanism
