I ricercatori del CERN di Ginevra hanno identificato una nuova particella che sperano possa aiutarli a spiegare la forza che tiene unita tutta la materia, chiamata forza nucleare forte.
La particella Xi è stata identificata grazie all'LHC, il più grande acceleratore di particelle al mondo. Si tratta di un particella subatomica prevista da decenni dalla teoria ma mai osservata in precedenza.
I ricercatori, grazie alla scoperta, avranno un nuovo angolo per analizzare una delle forze fondamentali della natura che regola le interazioni tra le particelle.
