| Summary: | We present a model of the dynamical evolution of relativistic heavy ion collisions, which combines second-order viscous hydrodynamics and microscopic transport. In particular, we present a hybrid approach with MUSIC hydrodynamics, and SMASH (Simulating Many Accelerated Strongly-interacting Hadrons) afterburner. In this work, we focus on low-<inline-formula> <math display="inline"> <semantics> <msub> <mi>p</mi> <mi>T</mi> </msub> </semantics> </math> </inline-formula> hadronic observables—identified hadron <inline-formula> <math display="inline"> <semantics> <msub> <mi>p</mi> <mi>T</mi> </msub> </semantics> </math> </inline-formula> spectra and anisotropic flow coefficients. We also demonstrate how the hadronic chemistry is altered by the hadronic non-equilibrium dynamics, for example by baryon-antibaryon annihilation. The new MUSIC + SMASH hybrid approach is also compared to existing MUSIC + UrQMD results.
