Description
$K_{1}$ and $K^{*}$ mesons are chiral partners whose vacuum widths are smaller than 100 MeV. This makes these mesons ideal to study possible effects of chiral symmetry restoration in heavy-ion collisions. In a recent theoretical study, the $K_{1}/K^{*}$ ratio in heavy-ion collisions is expected to be substantially larger than the statistical hadronisation model predictions. The study of the $K_{1}/K^{*}$ ratio as a function of multiplicity in different collision systems ranging from $pp$ to central heavy-ion collisions can provide crucial information on effects of the chiral symmetry restoration. The ALICE detector has an excellent capability of particle identification, so the $K_{1}$ meson can be measured via its hadronic decay channels such as $K_{1}^{-}\to \rho^{0}K^{-}$ and $K_{1}^{-}\to \pi^{-}\bar{K}^{*0}$. In this poster, the feasibility study of the $K_{1}$ measurement in $pp$ collisions with ALICE is presented.
