“…The p scattering and absorption on nuclei is a direct way to access the p-nucleus optical potential. Such experiments have been performed at LEAR [175,176] and KEK [177] in the early 80's. Their optical model analysis has led to the conclusion that the antiproton-nucleus optical potential is moderately attractive (Re(V opt ) = −(0-70) MeV) and strongly absorptive (Im(V opt ) = (2-3)Re(V opt )).…”

In this review we first outline the basics of transport theory and its recent generalization to offshell transport. We then present in some detail the main ingredients of any transport method using in particular the Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) implementation of this theory as an example. We discuss the potentials used, the ground state initialization and the collision term, including the in-medium modifications of the latter. The central part of this review covers applications of GiBUU to a wide class of reactions, starting from pion-induced reactions over proton and antiproton reactions on nuclei to heavy-ion collisions (up to about 30 AGeV). A major part concerns also the description of photon-, electron-and neutrino-induced reactions (in the energy range from a few 100 MeV to a few 100 GeV). For this wide class of reactions GiBUU gives an excellent description with the same physics input and the same code being used. We argue that GiBUU is an indispensable tool for any investigation of nuclear reactions in which final-state interactions play a role. Studies of pion-nucleus interactions, nuclear fragmentation, heavy-ion reactions, hypernucleus formation, hadronization, color transparency, electronnucleus collisions and neutrino-nucleus interactions are all possible applications of GiBUU and are discussed in this article.

“…The experimental data obtained exhibit a pronounced diffraction structure. This behaviour of the measured observables in the fA elastic scattering occurs both at 179 MeV and 50 MeV [4] energy and can be related to a high probability of fiN annihilation so that the probability of antiproton absorption by nuclei is much greater than that of protons.…”

“…In [1,2,[5][6][7] the differential cross sections offA elastic scattering are described by making use of phenomenological optical potentials. To calculate the differential cross sections of antiproton-nucleus elastic scattering in [ 1,2,8] KMT nonrelativistic impulse approximation [9] was used while in [ 10,11 ] they are studied by using the relativistic impulse approximation. Reference [ 12] should also be mentioned, where Frahn's closed formalism was used to describe the elastic scattering of antiprotons on 12C nuclei.…”

Energy and Mass-Number Dependence of Hadron–Nucleus Total Reaction Cross Sections

We thoroughly investigate how proton-nucleus total reaction cross sections depend on the target mass number A and the proton incident energy. In doing so, we systematically analyze nuclear reaction data that are sensitive to nuclear size, namely, proton-nucleus total reaction cross sections and differential elastic cross sections, using a phenomenological black-sphere approximation of nuclei that we are developing. In this framework, the radius of the black sphere is found to be a useful length scale that simultaneously accounts for the observed proton-nucleus total reaction cross section and first diffraction peak in the proton elastic differential cross section. This framework, which is shown here to be applicable to antiprotons, is expected to be applicable to any kind of projectile that is strongly attenuated in the nucleus. On the basis of a cross-section formula constructed within this framework, we find that a less familiar A 1/6 dependence plays a crucial role in describing the energy dependence of proton-nucleus total reaction cross sections.
