| Abstract | Recent measurements of high multiplicity pp collisions at LHC energies have revealed that these systems exhibit features similar to quark-gluon plasma, such as the presence of radial and elliptic flow and strangeness enhancement, traditionally believed to be only achievable in ultra-relativistic nucleus-nucleus collisions [1]. To pinpoint the origin of these phenomena and to bring all collision systems in equal footings, along with charged-particle multiplicity (Nch), lately several event shape observables such as transverse spherocity (S0), transverse sphericity (ST), charged particle flattenicity (ρch), and relative transverse activity classifiers such as RT, Rmin T , and Rmax T has been used extensively in experiments as well as in the phenomenological front. One of the explanations of the QGP-like behavior is the multipartonic interactions (MPI) based picture with colour reconnection and ropes. The event-shape classifiers have shown a significant correlation with MPI which makes them the ideal tool for the understnding of QGP-like effects. |
