WebSep 7, 2011 · The WW model with strong Feynman scaling violation leads to a continuous decrease of the energy fraction released to the secondaries produced in very high energy interactions. Eq. gives the inelasticity energy dependence (10) K (s) = K 0 (s s 0) (α ′ − α), while for the modified Feynman scaling formula it is (11) K (s) = K 0 (s s 0) α F.
