英文摘要: The formation mechanism of fragments with strangeness in collisions of antiprotons on nuclei has been investigated within the Lanzhou quantum molecular dynamics (LQMD) transport model. Production of strange particles in the antiproton-induced nuclear reactions is modeled within the LQMD model, in which all possible reaction channels such as elastic scattering, annihilation, charge exchange, and inelastic scattering in antibaryonbaryon, baryon-baryon, and meson-baryon collisions have been included. A coalescence approach is developed for constructing hyperfragments in phase space. The hyperfragments are formed within the narrower rapidities. It has the advantage of producing heavier hyperfragments and hypernuclides with strangeness s = -2 (double-Lambda fragments) and s = 1 ((Lambda) over bar fragments) in antiproton-induced reactions.
