The primary goal of the GlueX experiment at Jefferson Lab is to map the spectrum of light hybrid mesons. GlueX, which has a linearly polarized photon beam and a large acceptance for both charged and neutral particles, has access to both the neutral, $\gamma p\to\eta\pi^{0}p$, and charged, $\gamma p\to\eta\pi^{-}\Delta^{++}$, processes. This presentation will discuss the amplitude analysis of $\eta

The COMPASS experiment at CERN collected a large sample of diffractively produced $\pi^-\pi^-\pi^+$ events.
The data contain signals from iso-vector resonances decaying into $\pi^-\pi^-\pi^+$. We extract the resonance signals by performing a detailed partial-wave analysis in bins of three-pion mass and squared four-momentum transferred from the beam to the target.
In this talk, we will present

I will discuss a recent calculation where for the first time we determined an exotic $J^{PC} = 1^{-+}$ hybrid meson resonance in lattice QCD. Working with SU(3) flavour symmetry, we found a narrow resonance with a large coupling to at least one axial-vector--psuedoscalar channel. A simple extrapolation to physical light-quark mass suggests a broad $\pi_1$ resonance decaying dominantly through the

Using the large COMPASS data set for diffractive three pion production, we investigate the contradictions found by previous experiments in the signal of the spin-exotic wave with spin, parity and charge conjugation quantum numbers $1^{-+}$. We determine a strong dependence on the analysis model as their cause and in turn create a model tuned to minimize such effects. Additionally, we study the rob

I will discuss the $\pi\eta^{(‘)}$ production in the double Regge model. The model explains the forward-backward asymmetry observed in this reaction by associating it with the exotic $P-$ wave, which in turn is related to the production of the putative $\pi_1$ hybrid meson. I will also discuss the Regge and Deck production of $\pi\pi$ resonances. The interference of the Deck and direct productio
