The first results on the production of K*(892)(+/-) resonance in inelastic pp collisions at LHC energies have been presented. The transverse momentum distributions, p(T)-integrated yields, and mean transverse momenta for charged K*(892) are consistent with previous measurements. The transverse momentum spectra for K*(892)(+/-) are found to become harder with increasing center-of-mass energy, and the yield does not significantly evolve with collision energy for low transverse momenta.
The first results on K*(892)(+/-) resonance production in inelastic pp collisions at LHC energies of root s = 5.02, 8, and 13 TeV are presented. The K*(892)(+/-) (;)has been reconstructed via its hadronic decay channel K*(892)(+/-) -> K-S(0) + pi(+/-) with the ALICE detector. Measurements of transverse momentum distributions, p(T)-integrated yields, and mean transverse momenta for charged K*(892) are found to be consistent with previous ALICE measurements for neutral K*(892) within uncertainties. For p(T) > 1 GeV/c the K*(892)(+/-) transverse momentum spectra become harder with increasing centre-of-mass energy from 5.02 to 13 TeV, similar to what previously observed for charged kaons and pions. For p(T) < 1 GeV/c the K*(892)(+/-) yield does not evolve significantly and the abundance of K*(892)(+/-) relative to K is rather independent of the collision energy. The transverse momentum spectra, measured for K*(892)(+/-) at midrapidity in the interval 0 < p(T) < 15 GeV/c, are not well described by predictions of different versions of PYTHIA 6, PYTHIA 8 and EPOS-LHC event generators. These generators reproduce the measured p(T)-integrated K*(+/-)/K ratios and describe well the momentum dependence for p(T) < 2 GeV/c. (c) 2022 European Organization for Nuclear Research.
