“…10 the empirical values of σ R , which are taken from the absorption cross section data. 72,76,77) From this figure, we find that even in the reactions involving antiprotons, the values of σ BS are consistent with the empirical values of σ R within the uncertainties although the values of σ R are rather scattered in the region of low incident energies. These results support the relevance of the BS picture for antiprotons, while the analyses of the data for other hadronic probes are in progress.…”

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.

“…It is in order to note here that several previous GM calculations of absorption cross sections (cf. [24,36]) were done in the semiclassical approximation, Eq. (69), neglecting the momentum transfer dependence of the elementary amplitude, although a more rigorous way is to apply Eqs.…”

We perform Glauber model calculations of the antiproton-nucleus elastic and quasielastic scattering and absorption in the beam momentum range ∼ 0.5 ÷ 10 GeV/c. A good agreement of our calculations with available LEAR data and with earlier Glauber model studies of thepA elastic scattering allows us to make predictions at the beam momenta of ∼ 10 GeV/c, i.e. at the regime of the PANDA experiment at FAIR. The comparison with the proton-nucleus elastic scattering cross sections shows that the diffractive minima are much deeper in thepA case due to smaller absolute value of the ratio of the real-to-imaginary part of the elementary elastic amplitude. Significant polarization signal forpA elastic scattering at 10 GeV/c is expected. We have also revealed a strong dependence of thepA absorption cross section on the slope parameter of the transverse momentum dependence of the elementarypN amplitude. ThepA optical potential is discussed.

“…The real and imaginary parts of the antiproton optical potential are key quantities which determinep-nucleus scattering at low [1,2,3] and intermediate [4] energies, as well as the existence of deeply boundN -nucleus states [5,6,7,8,9,10]. ThepN interaction in nuclear matter is, moreover, a challenging problem by itself, since it is subject to strong in-medium modifications.…”

Antiproton-nucleus collisions simulation within a kinetic approach with relativistic mean fields

The Giessen Boltzmann-Uehling-Uhlenbeck transport model with relativistic mean fields is used to simulatep-nucleus collisions. Antiproton absorption cross sections and momentum distributions of annihilation products are calculated by varying thep coupling strength to the mean meson fields.Parameters of the antiproton-nucleus optical potential are extracted from the comparison of the model calculations with experimental data.
