First observation of Λ(1520)→γΣ⁰ and Λ(1670)→γΣ⁰ decays with branching fraction measurements that agree with SU(3) symmetry but disagree with some quark model predictions.
The relative branching fraction B(phi → K_S0 K_L0)/B(phi → K+ K-) is measured as 0.628 ± 0.022 ± 0.015 ± 0.017, consistent with isospin symmetry.
Flux-averaged cross sections for n-bar p to K+K-pi+ and K+K-pi+pi0 are measured as 0.53 and 1.09 mb using tagged antineutrons from J/psi decays.
MAGE-HEP introduces a GUI-driven workflow environment for reproducible Monte Carlo analyses in high-energy physics organized by project-study-run hierarchy.
The branching fraction of η → e⁺e⁻e⁺e⁻ is measured to be (2.63 ± 0.34_stat ± 0.16_syst) × 10^{-5}.
