Search for the $Y (2175)$ in the photoproduction cross section measurement of $γ p \to ϕ π^{+} π^{-} p$ at GlueX

GlueX Collaboration

Based on 334 pb $^{- 1}$ of photoproduction data collected with the GlueX detector at Jefferson Lab, we have measured for the first time the cross section of the exclusive reaction $…

Search for photoproduction of axion-like particles at GlueX

GlueX Collaboration, S. Adhikari, C. S. Akondi +142

We present a search for axion-like particles, $a$ , produced in photon-proton collisions at a center-of-mass energy of approximately 4 GeV, focusing on the scenario where the $a$ -gl…
