[PWGLF] Add new task: PWGLF/TableProducer/Nuspex/deuteronInTriggeredEvents

[Cristian-Moscatelli]

I created a new task, named deuteronInTriggeredEvents.cxx (PWGLF/TableProducer/Nuspex), to study the (anti-)deuteron pT spectrum in jet-triggered pp collisions. The task is based on nucleiSpectra.cxx (same directory), but provides further selections for events. The analysis flow is the following:

1. Apply standard event selection: sel8 + |z_vtx| < 10 cm;
2. Select events "containing" at least one jet with pT above a given threshold (valid jet);
3. Produce derived data containing (anti-)deuteron candidates for offline analysis.

Regarding the processData, the event selection is performed using the skimmed dataset. Specifically, the trigger list used are fChJetLowPt and fChJetHighPt. Apart from this, this part is analogous to nucleiSpectra.cxx.

As for the processMC, the event selection is applied by checking if the event "contains" one valid jet. The same jet definition used in the skimming procedure is adopted:

• R_jet < 0.6;
• |eta_jet| < 0.9;
• pT thresholds of 30 and 55 GeV/c for the two triggers, respectively.

These event selections are applied to the reconstructed events, and (anti-)deuteron candidate selection follows the same strategy as in nucleiSpectra.cxx. In addition, a dedicated table has been introduced to store MC generated events containing at least one valid jet. This is intended for normalization of the final spectra to the number of jet-triggered events.

This task can also provide a MB analysis, as the jet-triggered event selection is configurable and can be disabled. Furthermore, the analysis can be extended to (anti-)p, (anti-)t, (anti-)He-3 and (anti-)He-4.

I would appreciate any feedback or suggestions. Thanks in advance.

Why is this not in PWGJE?
