Using the LHCb and ALICE detectors in the fixed-target mode at the LHC offers unprecedented possibilities to study the quark, gluon and heavy-quark content of the proton and nuclei in the poorly known region of the high-momentum fractions. We review our projections for studies of Drell-Yan, charm, beauty and quarkonium production with both detector set-ups used with various nuclear targets and the LHC proton beams. Based on this, we show the expected improvement in the determination of the quark, charm and gluon proton and nuclear PDFs as well as discuss the implication for a better understanding of the cold-nuclear-matter effects in hard-probe production in proton-nucleus collisions.
When assessing the effectiveness of ammunition designed to destroy various aerodynamic and ballistic targets, as the initial data on the vulnerability of the destruction objective, we use indicators obtained during experimental studies of the processes of fragments and fragment flow collision with various fragments of the target design. The results depend not only on the speed and mass of individual fragments, but also on their shape and location in the flow. The paper gives the results of the testing of an explosive thrower which provides the creation of a high-speed, i.e. ~5 km/s, flow of fragments of a given shape. Findings of research show satisfactory agreement between the results of calculations carried out in two- and three-dimensional statements with experimental data on high-speed throwing of a group of compact, parallelepiped, steel preformed fragments weighing 20 g each
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
