Measurement of Λ Polarization in the π ¯ p → K 0 Λ Reaction at p π¯ = 1.33 GeV/ c toward a New Λ p Scattering Experiment

T. Sakao, K. Miwa, J. K. Ahn, Y. Akazawa et autres

Abstract Understanding the spectrum and dynamics of excited nucleon states ($N^{*}$ resonances) remains a central challenge in hadron physics, as these resonances emerge in intermediate states of $\pi N$ and $\gamma N$ interactions. The dynamical coupled-channel models addressing this problem rely critically …
