First Simultaneous K−p→Σ0π0, Λπ0 Cross …

Simultaneous measurements of the K−p→Σ0π0 and K−p→Λπ0 cross sections below 100 MeV/c kaon momentum have been performed. The kaon beam delivered by the DAΦNE collider was exploited to detect K− absorptions on hydrogen atoms populating the gas mixture of the KLOE drift chamber. The cross sections are determined with the highest yet obtained precision in the low kaon momentum regime [σK−p→Σ0π0=42.8±1.5(stat)−2.0+2.4(syst)mb and σK−p→Λπ0=31.0±0.5(stat)−1.2+1.2(syst)mb] impacting on pending questions in several fields, ranging from nuclear and particle physics, to astrophysics.Received 9 November 2022Accepted 8 September 2023DOI:https://doi.org/10.1103/PhysRevC.108.055201©2023 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasInelastic scattering reactionsMeson & hyperon induced nuclear reactionsNuclear Physics
