  We compare phenomenological results from 3+1d quasiparticle anisotropic
hydrodynamics (aHydroQP) with experimental data collected in LHC 2.76 TeV Pb-Pb
collisions. In particular, we present comparisons of particle spectra, average
transverse momentum, elliptic flow, and HBT radii. The aHydroQP model relies on
the introduction of a single temperature-dependent quasiparticle mass which is
fit to lattice QCD data. By taking moments of the resulting Boltzmann equation,
we obtain the dynamical equations used in the hydrodynamic stage which include
the effects of both shear and bulk viscosities. At freeze-out, we use
anisotropic Cooper-Frye freeze-out performed on a fixed-energy-density
hypersurface to convert to hadrons. To model the production and decays of the
hadrons we use THERMINATOR 2 which is customized to sample from ellipsoidal
momentum-space distribution functions. Using smooth Glauber initial conditions,
we find very good agreement with many heavy-ion collision observables.
