N2  - The beam energy dependence of   v4  (the quadrupole moment of the transverse radial flow) is sensitive to the nuclear equation of state (EoS) in mid-central Au + Au collisions at the energy range of   3<sNN−−−−√<30  GeV, which is investigated within the hadronic transport model JAM. Different equations of state, namely, a free hadron gas, a first-order phase transition and a crossover are compared. An enhancement of   v4  at   sNN−−−−√≈6  GeV is predicted for an EoS with a first-order phase transition. This enhanced   v4  flow is driven by both the enhancement of   v2  as well as the positive contribution to   v4  from the squeeze-out of spectator particles which turn into participants due to the admixture of the strong collective flow in the shocked, compressed nuclear matter.
