Heavy-ion collisions at the LHC—Last call for predictions

In peripheral collisions at LHC, part of the large angular momentum of the 
\ncolliding ions could be collectively transferred to the midrapidity 
\ninteraction region giving rise to a spinning quark gluon plasma fireball.
\nIf the intrinsic angular momentum of the QGP fireball is large enough, there
\nwill be remarkable effects on several observables such as elliptic flow, 
\ntransverse momentum spectra and hadron multiplicities. 
\nBy taking advantage of a recent full calculation of the microcanonical and
\ncanonical ensembles of ideal relativistic quantum gases at fixed intrinsic
\nangular momentum, we give quantitative predictions of those observables
\nat LHC. In a statistically equilibrated spinning fireball, the predicted 
\nazimuthal momentum anisotropy is very similar to that generated by the 
\npressure gradients in usual hydrodynamical approach; transverse momentum spectra 
\nare broadened; the chemical freeze-out temperatures determined
\nby means of hadronic abundances could decrease with respect to central
\ncollisions. However, the most peculiar feature is an azimuthal anisotropic 
\nnet polarization of produced hadrons, for which we provide quantitative 
\npredictions and momentum dependence.
