摘要：

Based on e(+)e(-) collision data collected by the BESIII detector at the BEPCII collider at center-of-mass energies from 2.000 to 3.080 GeV, a partial-wave analysis is performed for the process e(+)e(-)-> K+K-pi(0). The Born cross section of the process e(+)e(-)-> K+K-pi(0) and its subprocesses e(+)e(-)-> phi pi(0), K*+(892)K- and K2*+(1430)K- are measured. The results for e(+)e(-)-> K+K-pi(0) and phi pi(0) are consistent with the BaBar measurements and with improved precision. By analyzing the cross sections of the subprocesses e(+)e(-)-> K*+(892)K- and K2*+(1430)K-, a structure with mass M-R = (2190 +/- 19 +/- 37) MeV/c(2) and width Gamma(R) = (191 +/- 28 +/- 60) MeV is observed with a combined statistical significance of 7.1 sigma. The measured resonance parameters suggest it can be identified as the phi(2170), thus the results provide valuable input to understand the internal nature of this state.
