We present results on the measurement of the I=½ Kπ S-wave through a model independent partial wave analysis of ηc decays to K0sK+π− and K+K−π0 produced in two-photon interactions. We also perform Dalitz plot analyses of the J/Ψ decays to π+π−π0, K+K−π0 and K0sK±π∓ produced in the initial state radiation process.

The Status

The status of the main ongoing analyses on light-meson spectroscopy at KLOE are presented. In particular, the most recent upgrades for the ϕ → ηe+e- analysis, in both charged (η → π+π-π0) and neutral (η → π0π0π0) channels of η decay, as well as the preliminary studies of the ϕ → π0e+e- process are reported. Latest upgrades on η → π+π-π0 Dalitz plot analysis are also shown. All the analyses are based on data collected at DAΦNE collider with the KLOE detector during the 2004/2005 data taking campaign.

GlueX at Jefferson Lab aims to study the light meson spectrum with an emphasis on the search for light hybrid mesons. To this end, a linearly-polarized [Formula: see text]GeV photon beam impinges on a hydrogen target contained within a hermetic detector with near-complete neutral and charged particle coverage. In 2016, the experiment completed its commissioning and subsequently started to take data in its design configuration. With the size of the data set so far, GlueX already exceeds previous experiments for polarized photoproduction in this energy regime. A selection of early results will be presented, focusing on beam asymmetries for pseudo-scalar and vector mesons. The potential to make significant contributions to the field of light-meson spectroscopy is highlighted by the observation of several known meson resonances. Furthermore, the strategy to map the light meson spectrum with amplitude analysis tools will be outlined.
