Description
Hyperon-proton scattering experiment is one of the most direct methods to study the hyperon-nucleon (YN) interaction, as in the case of the NN interaction.
Although it had been experimentally difficult for a long time due to short lifetime of hyperons, we successfully performed high-statistics Σ±p scattering experiment at J-PARC.
More YN scattering data for various channels and observables is essential to establish realistic baryon-baryon interaction theories such as the chiral effective field theory extended to the YN interaction.
As the next step, we are now preparing Λp scattering experiment using photo-produced Λ at BL33LEP at SPring-8.
we aim at measuring the differential cross section of the Λp scattering with good precision of 15% in the Λ momentum range of 300-600 MeV/c.
In this experiment, we combine the target surrounding detector system CATCH, which worked well in the previous YN scattering experiment, and the spectrometer system used in the LEPS experiment.
In this talk, I will introduce the overview of the Λp scattering experiment at BL33LEP and preparation status.
