Could the task name (and source file) be a bit more specific?
gen immediately addresses MC generator level which I guess it is not the aim
And corr is ambiguous having in mind the task is whithin the TwoParticleCorrelations directory
As it seems that the FT0 is being considered, what about something like long range correlations?

It is safe here to also use the RecoDecay method
