Description
Directed flow serves as one of the key observable to understand the
properties of the hot and dense matter produced in ion-ion collisions.
We report on systematics and detector effects study in the directed
flow measurement using the reaction plane estimate provided by the
sidewards deflection of neutral spectators measured with the help of ALICE Zero Degree Calorimeter detectors.
Effects from variation in the beam crossing parameters on the reaction
plane resolution are studied via cross correlations between spectator
deflection in the plane transverse to the beam direction.
Systematic uncertainties of the measured signal are assessed by comparing
results from different flow measurement techniques, such as the scalar product and the event plane methods.
