FORWARD PARTICLE PRODUCTION

Wounded quark model (WQM) works for dn/dh 3d hydrodynamic models also describe qualitatively dn/dh WQM: Barej, Bzdak, Gutowski, PRC 97 (2018) 034901 3d hydro: Bozek, Broniowski, PLB 739, 304 (2014)

DETAILES OF FORWARD PRODUCTION

Wounded quark model (WQM) OK for centrality of dn/dh v2(h) scales approximately with dn/dh WQM: Barej, Bzdak, Gutowski, PRC 97 (2018) 034901
