Description
The study of short-lived hadronic resonances in heavy-ion collisions
provides information about strangeness production and the hadronic phase of the
system. Resonance measurements in pp collisions set the baseline to which heavy-ion collisions are compared as well as contribute to the understanding of particle
production mechanisms through comparison with different model predictions. At the LHC, ALICE has collected data in pp collisions at $\sqrt{s}$ = 0.9, 2.76, 5.02, 7, 8 and 13 TeV.
The $\phi$(1020), which is a bound $s\bar{s}$ state, is reconstructed at mid-rapidity via its hadronic decay channel $\phi\rightarrow K^{+}+K^{-}$, both without particle identification and by using the information of the Time Projection Chamber (TPC) and Time of Flight (TOF) detectors to identify the decay products.
In this contribution, we report on transverse momentum ($p_{\rm T}$) spectra, integrated yields and $\langle p_{\rm T}\rangle$ measured for the $\phi$-meson in pp collisions at several LHC energies. These include the first results on $\phi$ production in pp collisions from the Run 2 of the LHC. These results are compared to model calculations.
