Abstract
This study presents the first measurement of the f$_{1}$(1285) resonance
using the ALICE detector in inelastic proton--proton collisions at a
center-of-mass energy of 13 TeV. The resonance is reconstructed at midrapidity
($|y| <$ 0.5) through the hadronic decay channel f$_{1} (1285) \rightarrow
\mathrm{K^{0}_{S} K^{\pm}\pi^{\mp}}$. Key measurements include the
determination of its mass, transverse-momentum integrated yield, and average
transverse momentum. Additionally, the ratio of the transverse-momentum
integrated yield of f$_{1}$(1285) to pion is compared with calculations from
the canonical statistical hadronization model. The model calculation, assuming
a zero total strangeness content for f$_{1}$(1285), reproduces the data within
1$\sigma$ deviation, shedding light on the quark composition of f$_{1}$(1285).
