On the relevance of matter and glue dynamics for baryon number fluctuations

Understand

We investigate the impact of the matter and glue dynamics on baryon number fluctuations and the kurtosis of baryon number distribution.

• This is done within the framework of QCD-improved low energy effective models.
• In particular we include the momentum scale dependence of the quark-meson scattering and the non-trivial dispersions of both, quarks and mesons.
• On the gluonic side we take into account the backreaction of the matter sector on the glue dynamics.
