Abstract
We show that the deviation from exponential behavior of the diffraction cone observed near t = −0.1 GeV2 both at the ISR and the LHC (so-called break) follows from a two-pion loop in the t-channel, imposed by unitarity. By using a simple Regge-pole model we extrapolate the “break” from the ISR energy region to that of the LHC.
