Detailed Description

This task fills histograms required to perform the analysis on the light nuclei yield.

The histograms filled in this tasks are used by the analysis macro

Monte Carlo

There are mainly three items studied here:

the acceptance x efficiency;
the \(DCA_{xy}\) distributions with respect to the primary vertex of primary and secondary;
the difference of the reconstructed \(p_{T}\) with respect to the MC truth \(p_{T}\)

Data

The histograms filled in this case are:

TPC counts after PID cuts as a function of \(p_{T}\) and centrality;
TOF signal for selected tracks as a function of \(p_{T}\) and centrality;
the \(DCA_{xy}\) distributions for selected tracks as a function of \(p_{T}\) and centrality

virtual

Parameters

options Deprecated parameter

Returns: void

The first check performed is on the particle type requested. If this type is AliPID::Unknown - the default one - the task does not process the information.

If the setup is fine the current event is loaded in memory together with the analysis manager and the event handler.

The first check perfomed is on the physics selection output stored in the mask given by the handler.

This mask contains also the information about the trigger of this events. For this analysis central, semi-central and minimum bias events are kept.

To perform the majority of the analysis - and also this one - the standard PID handler is required.

The centrality selection in PbPb uses the percentile determined with V0.

In this step only events with centralities between 0% and 80% are kept.

Primary vertex displacement cut. This cut is harcoded and it is equal to 10 cm of max displacement in z with respect to the center of the coordinate system.

The magnetic field cut - enabled only if fRequireMagneticField \(\neq 0\) - selects only events with magnetic field with the same sign of fRequireMagneticField

At the stage of event selection the Flattening is applied. This technique makes flat the centrality distribution using a pseudo-random selection based on prior probabilities. A complete description of this technique is present in the documentation of the Flatten function.
