Query: Unfolding the effects of final-state interactions and quantum statistics
  in two-particle angular correlations   Angular correlations of identified particles measured in ultrarelativistic
proton-proton (pp) and heavy-ion collisions exhibit a number of features which
depend on the collision system and particle type under consideration. Those
features are produced by mechanisms, such as (mini)jets, elliptic flow,
resonance decays, and conservation laws. In addition, of particular importance
are those related to the quantum statistics (QS) and final-state interactions
(FSIs). In this paper we show how to unfold the QS and FSI contributions in
angular correlation functions by employing a Monte Carlo approach and using
momentum correlations (femtoscopy), focusing on pp reactions. We validate the
proposed method with PYTHIA 8 Monte Carlo simulations of pp collisions at
$\sqrt{s}=13$ TeV coupled to calculations of QS and FSI effects with the
Lednick\'y and Lyuboshitz formalism and provide predictions for the unfolded
effects. In particular, we show how those effects modify the shape of the
angular correlation function with emphasis on pions and protons. Most
importantly, specific structures observed in the near-side region for both
baryon-baryon and baryon-antibaryon pairs, originating from the strong
interaction, are unveiled with the proposed method.
