Description

The Standard Model (SM) of particle physics is the most successful theory in describing fundamental particles and their interactions. It characterizes ordinary hadronic matter as consisting of quark-antiquark pairs or three-quark combinations, forming mesons and baryons. Beyond this, the SM also allows the existence of exotic hadrons composed of more than three quarks or a bound state of gluons. One notable example is the glueball, which is made entirely of gluons arising from gluon self-interactions. Lattice QCD calculation predicts the mass of the lightest scalar glueball to be in the range of 1500–1700 MeV/c${}^2$ having quantum numbers, J${}^{PC}$ = $0^{++}$. However, the experimental search for glueballs is challenging due to their mixing with nearby mesonic states sharing identical quantum numbers. The large statistics data collected by the ALICE detector during Run 3 at the highest centre-of-mass energy offers a unique opportunity to explore the glueball hypothesis, study its properties and internal structure, and probe the standard model predictions. This report will present the invariant mass distributions of higher-mass resonances in the range 1000–3000 MeV/c${}^2$. The analysis is performed through the decay channels ${\mathrm{K}}_{\mathrm{S}}^0{\mathrm{K}}_{\mathrm{S}}^0$ and ${\mathrm{K}}^{+}{\mathrm{K}}^{-}$ in pp collisions at $\sqrt{s}$ = 13.6 TeV using ALICE detector at midrapidity.
