In this Letter, the first measurement of the inelastic cross section for antitriton−nucleus interactions is reported, covering the momentum range of 0.8≤p<2.4 GeV/c. The measurement is carried out using data recorded with the ALICE detector in pp and Pb−Pb collisions at a centre-of-mass energy per nucleon of 13 TeV and 5.02 TeV, respectively. The detector material serves as an absorber for antitriton nuclei. The raw yield of (anti)triton nuclei measured with the ALICE apparatus is compared to the results from detailed ALICE simulations based on the GEANT4 toolkit for the propagation of (anti)particles through matter, allowing one to quantify the inelastic interaction probability in the detector material. This analysis complements the measurement of the inelastic cross section of antinuclei up to A=3 carried out by the ALICE Collaboration, and demonstrates the feasibility of the study of the isospin dependence of inelastic interaction cross section with the analysis techniques presented in this Letter.
In Vagabondaggio from the early collection Il gioco del rovescio, Tabucchi undertakes an oneiric and personal approach to the life and work of the Italian symbolist poet Dino Campana (1885–1932). The text is based on Nietzsche’s aphorism "Reisende und ihre Grade" ( Menschliches, Allzumenschliches), which establishes five categories of voyagers. Tabuchi uses these as stages in the protagonist’s quest for personal aesthetics. The aesthetics itself alludes to major motives in Campana’s masterpiece, Canti Orfici.
