Spin Density Matrix Elements in Exclusive $ω$ Meson Muoproduction $^{*}$

M. G. Alexeev, G. D. Alexeev, A. Amoroso +197

We report on a measurement of Spin Density Matrix Elements (SDMEs) in hard exclusive $ω$ meson muoproduction on the proton at COMPASS using 160 GeV/ $c$ polarised $μ^{+}$ and $ μ^{…

Triangle Singularity as the Origin of the $a_{1} (1420)$

G. D. Alexeev, M. G. Alexeev, A. Amoroso +194

The COMPASS experiment recently discovered a new isovector resonance-like signal with axial-vector quantum numbers, the $a_{1} (1420)$ , decaying to $f_{0} (980) π$ . With a mass too close…
