Tracking in Antiproton Annihilation Experiments

A major ingredient of the planned new accelerator complex FAIR, to be constructed at the GSI, Darmstadt, Germany, is the availability of antiproton beams with high quality and intensity. Among the experiments which will make use of this opportunity is PANDA, a dedicated experiment to study antiproton annihilations on nucleons and nuclei. This article gives an overview on the foreseen techniques...

Delta Excitation in Antiproton-deutron Annihilation *

The ∆-excitation in pd annihilation at rest was studied. The annihilation amplitude from the statistical model and the πN amplitude from the resonance model were adopted in our calculations. We analyze the invariant mass of the π + p and π − p systems selecting the protons with momenta above 400 MeV/c and with respect to the different final reaction channels. Our model reproduces reasonably the...

Strangeness production in antiproton-nucleus annihilation

Abstract. The results of the microscopic transport calculations of p̄-nucleus interactions within a GiBUU model are presented. The dominating mechanism of hyperon production is the strangeness exchange processes K̄N → Yπ and K̄N → ΞK. The calculated rapidity spectra of Ξ hyperons are significantly shifted to forward rapidities with respect to the spectra of S = −1 hyperons. We argue that this shif...

Antiproton-Hydrogen annihilation at sub-kelvin temperatures

The unique features of the LEAR (low-energy antiproton ring) facility at CERN made recently possible the synthesis of few antihydrogen atoms [1]. This effort would be pursued with the antiproton deccelerator (AD) project [2] and would make possible the storage of sensible amounts of antihydrogen. This project reinforces the already active interest to investigate several theoretical and experime...
