Physicists discover rare hypernucleus, a component of strange matter


It looks like not all is going bad for Italian researchers, after the trial of the seismologists: physicists from Italy have discovered the first evidence of a nucleus that doesn’t exist in nature and survives only for 10-10 seconds when created in a laboratory. Strange matter Hypernuclei contain all sorts of protons and neutrons, but unlike regular nuclei, they also contain at least a hyperon, a particle that consists of three quarks, including at least one strange quark; hypernuclei are considered to be the core of strange matter that may exist in distant parts of the universe and could prove valuable to researchers in understanding this phenomena. Whoa! Wait a…
