First Model-Independent Measurement of the Spin Triplet $p\Lambda$ Scattering Length from Final State Interaction in the $\vec{p}p\to p{K}^{+}\Lambda$ Reaction

TOF Collaboration, F. Hauenstein, E. Borodina +24

The $\vec{p}p\to p{K}^{+}\Lambda$ reaction has been measured with the COSY-TOF detector at a beam momentum of $2.7\mathrm{GeV}/c$. The polarized proton beam enables the measurem…
