Duality structure of inclusive diffraction dissociation

Abstract

The duality structure of diffraction dissociation is studied in a triple-Regge (TR) analysis of the diffractive process $\mathrm{pp}\ensuremath{\rightarrow}\mathrm{pX}$. A scheme (normal scheme) is proposed which is quite different from the scheme previously suggested by many people (abnormal scheme). Diffractive resonance production is dual to the ${P}_{t}{P}_{t}{P}_{0}$ (Pomeron exchange) term in the abnormal scheme, whereas it is dual to the ${P}_{t}{P}_{t}{R}_{0}$ (ordinary Reggeon exchange) term in our normal scheme. From a careful TR analysis performed with much more data, we conclude that the data favor our normal scheme at least for $0.1\ensuremath{\lesssim}|t|\ensuremath{\lesssim}0.5$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. Here $t$ is the mass squared of the external Pomeron (${P}_{t}$).
