Various flow phenomena of black particles (b-particles) and grey particles (g-particles) produced in magnesium-emulsion (Mg-Em) collisions at 4.5 A GeV/c are reported. These flows are directed and elliptic transverse flows (v 1 and v 2) related by the azimuthal angle (phgr), directed and elliptic reaction plane flows (v R1 and v R2) related by the projected angle (ψ) on the ... إقراء المزيد
