Description
The lifetimes of short-lived hadronic resonances are comparable to the hadronic phase of the medium produced in high-energy collisions. Thus, these resonances are sensitive to the re-scattering and regeneration processes in the time interval between the chemical and kinetic freeze-out, which might affect the resonance yields. In addition, event shape observables like transverse spherocity are sensitive to the hard and soft processes and they represent a useful tool to separate the isotropic and jetty events in pp collisions. Furthermore the measurements in small systems are used as a reference for ion-ion collisions and are helpful for the tuning of Quantum Chromodynamics (QCD) inspired event generators. In this contribution, we present recent results on $K^*(892)^{0}$ obtained by the ALICE experiment in pp collisions at several collision energies, event multiplicities and as a function of transverse spherocity. The results include the transverse momentum spectra, yields and their ratio to long-lived particles. The measurements will be compared with model predictions and measurements at lower energies.
