Summary
The open question of matter-antimatter symmetry can be investigated by measuring the antiproton flux in high atmosphere. In this paper a balloon-borne experiment using a superconducting magnet coupled to a tracking calorimeter is proposed to carry out such measurements at latitudes of low geomagnetic cut-off. An overwiev on further possible developments such as search for antinuclei to be performed with future planned facilities (NASA Space Station) is also presented.
Riassunto
La questione ancora aperta della simmetria tra materia e antimateria può essere esplorata, misurando il flusso di antiprotoni in alta atmosfera. In questo lavoro si propone un esperimento trasportato su pallone che impiega un magnete superconduttore accoppiato ad un calorimetro tracciante atto ad eseguire tali misure a latitudini a basso taglio geomagnetico. Si presenta pure una panoramica su possibili ulteriori sviluppi come la ricerca di antinuclei da eseguire con le future facilities in progetto (Stazione Spaziale della NASA).
