Description
Using hydrodynamics we explore the effects of the initial state,
baryon stopping and baryon number transport on various observables such
as spectra, elliptic flow and particle yields for heavy ion collisions
at beam energies from sqrt{s_{NN}}=7.7 to 200 GeV. We find that
observed phenomena such as the centrality dependent freeze out
parameters as well as the apparent difference in particle and
anti-particle v_2 can be explained by a collective hydrodynamic
expansion, once baryon stopping and baryon number conservation are
properly taken into account. We will further discuss how the various
stages of the collision contribute to the p_{t} spectra, the mass dependence of T_{eff} and particle ratio fluctuations.
