Behavior of the diffractive cross section in hadron-nucleus collisions

Abstract

A phenomenological analysis of diffractive dissociation of nuclei in proton-nucleus and meson-nucleus collisions is presented. The theoretical approach employed here is able to take into account at once data of the HELIOS and EHS/NA22 collaborations that exhibit quite different atomic mass dependences. Possible extensions of this approach to hard diffraction in nuclear processes are also discussed.Comment: 5 pages, 2 figure

Estimate of the single diffractive heavy quark production in heavy ion collisions at the CERN LHC

“…These issues were first addressed in Ref. [21], where an analysis of diffractive dissociation of nuclei in proton-nucleus and meson-nucleus was presented. Here, we have chosen the option (a) due to its simplicity of implementation.…”

On integrability of the Killing equation

“…where n and p are the dimension of space(-time) M and the order of KTs, respectively. Here, rank E (p) agrees with the upper limit of the BDTT formula (5); rank I (p,p) denotes the number of linearly independent components of the integrability condition (37). If C ≤ 1, we definitely need the derivatives of I (p,p) to determine the dimension of the space of KTs and thus r 0 > 0.…”

“…The integrability conditions for p ≥ 3 were discussed in [33]. Similar techniques have been applied to other hidden symmetries [34,35,37,36,38,39].…”

“…Appendix B presents a prolongation procedure for the Killing equation up to order 2. A derivation of the integrability condition (37) have been posted in Appendix C. In Appendix D, we discuss the Killing-Yano equation by using our analysis.…”

“…As is the case with the prolonged equations (8)- (10), there are still a lot of derivative terms left in the right-hand side of Eq. (37). Then again, we can rewrite all these terms in Eq.…”
