Two-particle angular correlation is one of the most powerful tools to studythe mechanism of particle production in proton--proton (pp) collision systemsby relating the difference between the azimuthal angle ($\Delta\varphi$) andthe rapidity ($\Delta y$) of the particles from a pair. Hadronization processesare influenced by various physical phenomena, such as resonance decay, Coulombinteractions, laws of conservation of energy and momentum, and others, becauseof the quark content of the particles involved. Therefore, each correlationfunction is unique and shows a different dependence on transverse momentum$p_{\mathrm{T}}$ and/or multiplicity. The angular correlation functionsreported by the ALICE Collaboration in pp collisions showed an anticorrelationin short range of ($\Delta y,\Delta\varphi$) for baryon pairs which is notpredicted by any theoretical model.\\ \indent In this contribution, thisbehavior will be investigated by studying identified charged hadrons (i.e.,$\pi^{\pm}$, $\rm K^{\pm}$, and p($\bar{\rm p}$)) in the $\Deltay,\Delta\varphi$ space in pp collisions at $\sqrt{s} = 13$ TeV recorded byALICE. In addition, to distinguish the various physical contributions,collisions with different multiplicities are analyzed separately and diversenormalization methods are applied.
