description | Recent results for high multiplicity pp and p-Pb collisions have revealed that they exhibit heavy-ion-like behaviors. To understand the origin(s) of these unexpected phenomena, event shape observables such as transverse spherocity and the relative transverse activity classifier (RT) can be exploited as a powerful tools to disentangle soft (non-perturbative) and hard (perturbative) particle production. The production of light-flavor hadrons is shown for various classes in pp collisions at measured with the ALICE detector at the LHC. The evolution of average transverse momentum with charged-particle multiplicity, and identified particle ratios as a function of pT for different are also presented. In addition, the system size dependence of charged-particle production in pp, p–Pb, and Pb–Pb collisions at is presented. The evolution of 〈pT〉 in different topological regions as a function of RT are presented. Finally, using the same approach, we present a search for jet quenching behavior in small collision systems. |

To understand the origin(s) of these unexpected phenomena, event shape observables such as transverse spherocity ($S_{\rm 0}^{p_{\rm T} = 1}$) and the relative transverse activity classifier ($R_{\rm{T}}$) can be exploited as a powerful tools to disentangle soft (non-perturbative) and hard (perturbative) particle production. Here, the production of light-flavor hadrons is shown for various $S_{\rm 0}^{p_{\rm T} = 1}$ classes in pp collisions at $\sqrt{s}$ = 13 $\textrm{TeV}$ measured with the ALICE detector at the LHC are presented. The evolution of average transverse momentum ($\langle p_{\rm T}\rangle$) with charged-particle multiplicity, and identified particle ratios as a function of $p_{\rm T}$ for different $S_{\rm 0}^{p_{\rm T} = 1}$ are also presented. In addition, the system size dependence of charged-particle production in pp, p-Pb, and Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV is presented. The evolution of $\langle p_{\rm T}\rangle$ in different topological regions as a function of $R_{\rm{T}}$ are presented. Finally, using the same approach, we present a search for jet quenching behavior in small collision systems.arXiv:2010.05038oai:cds.cern.ch:27413672020-10-10 |
