Rotated Gaussian solutions
Note: (r’, k’) in fireball frame rotated wrt lab frame (r,k)
Note: in this talk, rotation in the (X,Z) impact parameter plane !

Role of EoS on acceleration
Lattice QCD type Eos is explosive
Tilt angle q integrates rotation in (X,Z) plane: sensitive to EoS!

Single particle spectra
In the rest frame of the fireball:
Rotation increases effective temperatures both in the
longitudinal and impact parameter direction
in addition to Hubble flows

Directed, elliptic and other flows
Note: model is fully analytic
As of now, only X = Z = R(t)spheroidal solutions are found
→ vanishing odd order flows
See next talk for fluctuations
From the single particle spectra→ flow coefficents vn

Reminder: Universal w scaling of v2
Notes: Rotation does not change thisJust modifiesRadial flow parameters

HBT radii for rotating spheroids
New terms with blue → Rotation decreases HBT radii similarly to Hubble flow.
Diagonal Gaussians in natural frame

HBT radii in the lab frameHBT radii without flow
But spheriodal symmetry of the solutionMakes several cross terms vanish → need for ellipsoidal solutions

Qualitatively rotation and flow similar
But need more time dependent calculations
and less academic studies(relativistic solutions)

SummaryObservables calculated
Effects of rotation and flowCombine and have same mass dependence
Spectra: slope increasesv2: universal w scaling remains valid
HBT radii:Decrease with mass intensifies
Even for spherical expansions:v2 from rotation.
Picture: vulcanoHow to detect the rotation?
Next step: penetrating probes
