Double-λ hypernuclear production in high-energy heavy-ion collisions

The production of double-λ hypernuclei was studied regarding three different mechanisms: (1) coalescence of a nuclear fragment from peripheral collisions and two A particles, (2) coalescence of two A particles, neutrons and protons due to central collisions, and (3) conversion of a ξ hypernucleus. The production probability is estimated for several projectile-target combinations at 5 and 14.5 GeV/nucleon.
