Amplitude analysis of the KS0KS0 system produced in the reaction π-p→KS0KS0n at 23 GeV/c (original) (raw)
AI-generated Abstract
An amplitude analysis of the KS0KS0 system produced in the reaction π-p → KS0KS0n at 23 GeV/c has been conducted using approximately 15,000 events. The study identifies a new state, termed the S'(1770), with parameters M=1.771 GeV/c and width Γ=0.200 GeV/c. The f'/f production ratio was determined to be 0.23, along with branching ratios for the decay processes involving the f-meson and h(2040)-meson. The results align well with existing experimental data, confirming known features of both charged and neutral KK systems.
