| Abstract | |
I argue that, because of the peculiar properties of the eta' meson, it is a promising probe of chiral dynamics. In particular, I show that a rotating gluon-dominated plasma might lead to an enhanced production of eta' with respect to statistical model expectations. The presence of a strong topological susceptibility might give a similar effect. In both cases, unlike the statistical model, I expect a nontrivial dependence on event geometry, such as initial volume and impact parameter. Hence, an observation of eta'/pi ratio depending strongly on impact parameter might be a good indication of chiral effects, either from vorticity or topological phases of QCD. (AU) | |
