Does the pomeron have two components

Experimental total and differential elastic cross sections are in remarkable agreement with the ansatz that the Pomeron contribution satisfies the relation P(πp) = (1/2)P(Kp)+(1/3)P(pp) weaker than the quark model relation P(πp) = P(KP) = (2/3)P(pp) and following from the assumption that the Pomeron has a second component satisfying the relation P(πp) = 2P(KP) = (4/9)P(pp). Sum rules obtained from this ansatz are satisfied to an accuracy of 1% by total cross section data from 6 to 200 GeV/c where the quark model relation has a consistent discrepancy of 15%. They are satisfied to better than 20% for differential cross section data at 3, 13.6, 5, 6 and 42 GeV/c over a range of t where cross sections change by several orders of magnitude and the ratio of Kp and pp amplitudes varies from 2/5 to 5 and violates the simple quark model prediction of 2/3 by large factors in both directions.
