TL;DR: In this article, the authors argue that minijet production provides a steadily increasing fraction of the total cross section in hadron-hadron collisions, rather than being a new phenomenon, this is the result of the hard tail of soft diffractive events becoming increasingly prominent.

TL;DR: In this paper, it is suggested that Regge corrections to an energy independent cross-section for the inclusive process a + b → c + X are expected to be absent in general only if both the channels (ab) and (ab c ) are exotic duality for two-body scattering which involves an unstable hadron.

TL;DR: The variation with energy and with Feynman's variablex of the production of ψ and ψ’ is a sensitive test of their production mechanism as discussed by the authors, and a simple parton model predicts that at relatively low energies production nearx=0 is strongly favored and that the invariant crosssection atx = 0 increases by two orders of magnitude between BNL and ISR energies.

TL;DR: In this article, the characteristics Ξ -signature of the quark-gluon plasma is discussed and the relative abundance of Ξ expected to be a peculiar feature for quark gluon plasmas formed in relativistic nuclear collisions can be readily observed by measuring the longitudinal polarization of Λ into which Ξ cascades.

TL;DR: In this paper, the authors explore how particle multiplicities in large transverse momentum reactions are affected by the way in which the detection apparatus is triggered, and show that the multiplicity of particles accompanying a large p T hadron is increased when it is required that there is a second large pT hadron in the opposite hemisphere.
