Spin Density Matrix Elements in Exclusive 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 meson muoproduction on the proton at COMPASS using 160 GeV/ polarised and $ μ^{…
First branching fraction measurement of the suppressed decay
LHCb collaboration, R. Aaij, C. Abellán Beteta +963
The baryon is unstable and usually decays into charmless final states by the transition. It can, however, also disintegrate into a meson and a…
The determination of the spin and parity of a vector-vector system
Liupan An, Ronan McNulty, Mikhail Mikhasenko
We present a construction of the reaction amplitude for the inclusive production of a resonance decaying to a pair of identical vector particles such as , , . The m…
Triangle Singularity as the Origin of the
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 , decaying to . With a mass too close…
and transition form factor revisited
M. Albaladejo, I. Danilkin, S. Gonzalez-Solis +7
In light of recent experimental results, we revisit the dispersive analysis of the decay amplitude and of the transition form factor. Within the framework of the K…
