Polarized antiprotons, produced by spin filtering with an internal polarized gas target, provide access to a wealth of single- and double-spin observables, thereby opening a new window to physics uniquely accessible at ...


The polarized antiproton - proton interactions at HESR will give a unique access to a number of new fundamental physics observables, which can be studied neither at other ...


To reveal rare reactions like the Drell-Yan process and the pbar annihilation, the PAX detector has to be conceived as a large acceptance apparatus capable of unambiguously ...
