### Description

The event-by-event fluctuations of the average transverse momentum, $\langle p_{\rm{T} }\rangle$, are studied as a function of transverse spherocity and average multiplicity in p$-$p collisions using PYTHIA8 event generator at $\sqrt{s}= 7$ TeV and 13 TeV. We compared the results for different spherocity classes to understand the contribution from the underlying events. Also, the energy dependence and the effect of different color reconnection and rope hadronisation models on the observables are investigated. The fluctuations studies are sensitive to the properties of phase transition from hadron gas to QGP in heavy-ion collisions. The investigation of such fluctuations in pp collision would serve as a baseline to understand the heavy-ion collisions.
