Descrizione
Our current knowledge of the baryon--baryon interaction suggests that the dineutron (n,n) and its strange analogue (Lambda,N) are unstable. In contrast, the situation is more favourable for the strange three-body system (n,n,Lambda), and even better for the four-body system T=(n,n,Lambda,Lambda) with strangeness -2, which is more likely to be stable under spontaneous dissociation. This new nucleus could be produced and identified in central deuteron--deuteron collisions via reaction d+d -> T+K+K.
