Abstract
The differential cross section for the quasi-free photoproduction reaction γn→ KΣ was measured at BGOOD at ELSA from threshold to a centre-of-mass energy of 2400MeV . Close to threshold the results are consistent with existing data and are in agreement with partial wave analysis solutions over the full measured energy range, with a large coupling to the Δ (1900) 1 / 2 - evident. This is the first dataset covering the K∗ threshold region, where there are model predictions of dynamically generated vector meson-baryon resonance contributions.File in questo prodotto:
