Description

Heavy-flavor hadrons, containing charm and beauty flavors are believed to be vital probes for the understanding of Quantum Chromodynamics (QCD) in high-energy hadronic collisions: right from the study of production mechanisms in proton-proton ($pp$) collisions to the investigation of Cold Nuclear Matter (CNM) effects in proton-nucleus (p--A) collisions and their suppression in the search of Quark Gluon Plasma (QGP) in nucleus-nucleus (A--A) collisions. Recently, the observation of heavy-ion-like features in small systems ($pp$ and p$-$A) like collective-like phenomena, strangeness enhancement etc, continues to generate considerable interest in the scientific community. In this regards, a cruial question arises, whether the QGP-like phenomena involve all the particles in the system or it is the effect of contributions from the processes like resonance decays, jets, underlying events (UE) etc. Therefore, small systems need to be re-investigated properly including the light and heavy-flavor sectors. In the present work, using transverse spherocity, one of the event-topology variables used to separate jetty and isotropic events from the pool of event samples, we aim to understand the production dynamics of heavy-flavors through the transverse momentum spectra, double differential yield and mean transverse momentum of J/$\psi$, $\rm D^{0}$ and $\Lambda_{c}^{+}$ as a function of charged-particle multiplicity. For the current analysis, the events are generated by using 4C tuned PYTHIA8 for $pp$ at $\sqrt{s}$ = 13 TeV, which is quite successful in explaining the heavy-flavor particle production at the LHC energies. We observe a clear dependence of spherocity on the production of J/$\psi$, $\rm D^{0}$ and $\Lambda_{c}^{+}$.
