Glueball search in pPb collisions at the LHCb experiment*

In the Standard Model of Particle Physics, hadrons can be formed as mesons, baryons but also tetraquarks, pentaquarks and even be made of only gluons, also called glueballs.  Many tetraquark and pentaquark states have been discovered by now, many of them by the LHCb collaboration, but glueballs are still up for conclusive experimental evidence. The LHCb detector at LHC can measure dikaon and dipion spectra with a high mass resolution and excellent particle identification capabilities. The forward kinematic region covered by the LHCb (2<y<4.5) is dominated by high gluon densities and, in principle, could be a source of glueball formation. Particles such as f₂(1275), f₂’(1525) and f₀(1710) still have unknow configuration. The yield modification of these particles in nucleus compared to known mesons may reveal their nature. This presentation is going to discuss the idea and the status of the analysis of di-kaon spectrum obtained in p+Pb collisions at √s =8.16 TeV, where gluon densities can get even higher or saturated.
