Event multiplicity dependence production of K∗(892)± resonance in pp collisions at √s = 13 TeV with the ALICE detector at the LHC

This thesis reports first measurements of K∗(892)± produced in pp collisions at √s = 13 TeV as function of the event multiplicity. The results include, for each multiplicity class considered, the differential transverse momentum (pT) spectrum, the mean transverse momentum ⟨pT⟩, the integrated yield (dN /dy), and the ratio of the K∗(892)± yield to the K0S one. The K∗(892)± has been studied at the same energy and compared with the neutral K∗ resonance production, as well as with results from different event generators.
