Scaling of particle and transverse energy production in $$^{208}$$Pb+$$^{208}$$Pb collisions at 158$$\cdot A$$ GeV

Abstract. Transverse energy, charged particle pseudorapidity distributions and photon transverse momentum spectra have been studied as a function of the number of participants ($$N_{part}$$) and the number of binary nucleon-nucleon collisions ($$N_{coll}$$) in 158$$\cdot A$$ GeV Pb+Pb collisions over a wide impact parameter range. A scaling of the transverse energy pseudorapidity density at midrapidity as $$\sim N_{part}^{1.08 \pm 0.06}$$ and …
