Description
Fluctuations in physics observables and flow effects in heavy-ion collisions
have been topics of particularly interest in recent years as they may provide
important signals regarding the formation of quark-gluon plasma, the existence of a critical point and the evolution of the system. Moreover, the fluctuations and correlations measured in the final stage have their sources at least partly in the initial fluctuations and the initial-state geometry provided the initial effects are not largely altered by the intermediate evolution of the system.
In the framework of the Glauber approach with the use of the GLISSANDO generator we provide predictions for basic initial state characteristics, like the number of target (projectile) participants and its event-by-event fluctuations as well as inelastic and production cross sections, for various p+A and A+A collisions. Such predictions are particularly interesting for those who study signals of the formation of quark-gluon plasma.
We also investigate sensitivity of the azimuthal eccentricity parameters and
the correlation of directions of the principal axes associated with the Fourier components to the particular variant of the Glauber Monte Carlo like the wounded-nucleon model, the mixed model or the hot-spot model. Moreover we show the role of the nucleus deformation in the geometry measures in relativistic heavy-ion collisions.
