Influence of the tetraneutron on the EoS under core-collapse supernovae and heavy-ion collisions conditions

Helena Pais, Conrado Albertus, M. Ángeles Pérez-García +1

Recently, a resonant state of four neutrons (tetraneutron) with an energy of $E_{4n}=2.37\pm 0.38(\mathrm{stat})\pm 0.44(\mathrm{sys})$ MeV and a width of $Γ=1.75\pm 0.22 \rm{(stat)} \p…
