Measurement of the $gamma nrightarrow K^0Sigma^0$ differential cross section over the $K^*$ threshold


الملخص بالإنكليزية

The differential cross section for the quasi-free photoproduction reaction $gamma nrightarrow K^0Sigma^0$ was measured at BGOOD at ELSA from threshold to a center-of-mass energy of SI{2400}{MeV}. A peak is observed at SI{2050}{MeV} where the cross section rises by approximately a factor of four. The available statistics prevent an accurate description of this structure, however it appears consistent with models describing a resonance driven by the constructive interference of dynamically generated vector meson-baryon states, where an equivalent model predicted the $P_C$ states observed at LHCb. If proven correct, this could indicate parallels between the strange and charmed quark sectors.
