Measurement of Spin-Density Matrix Elements in $\varphi (1020)\to K_S^0{K}_L^0$ Photoproduction with a Linearly Polarized Photon Beam at $E_{\gamma }=8.2-8.8$ GeV

GlueX Collaboration

We measure the spin-density matrix elements (SDMEs) for the photoproduction of $\varphi (1020)$ off of the proton in its decay to $K_S^0{K}_L^0$, using 105 pb${}^{-1}$ of data collected with…
