In order to test theoretical frameworks of the baryon-baryon interactions and to confirm the "Pauli effect between quarks" for the first time, we propose an experiment to measure low-energy hyperon proton scattering cross sections in the following channels with high statistics, 1. Σ
- p elastic scattering, 2. Σ- p → Λn inelastic scattering, 3. Σ+ p elastic scattering. According to theoretical models based on quark-gluon picture for the short range part of the baryon-baryon interactions, the Σ+ p channel is expected to have an extremely repulsive core due to the Pauli effect between quarks, which leads a Σ+ p cross section twice as large as that predicted by conventional meson exchange models with a phenomenologically treated short range repulsive core. In addition, measurement of the Σ- p channel where the quark Pauli effect is not effective is also necessary to test the present theoretical models based on meson exchange picture with the flavor SU(3) symmetry. Thus this experiment will provide essential data to test the frameworks of the theoretical models of the baryon-baryon interactions and to investigate the nature of the repulsive core which has not been understood yet. In order to overcome the experimental difficulties in measuring low-energy hyperon proton scattering, we will use a new experimental technique in which a liquid H2 target is used as hyperon production and hyperon scattering targets with a detector system surrounding the LH2 target for detection of a scattered proton and a decay product from a hyperon. The hyperon scattering event is kinematically identified. Because imaging detectors used in past experiments are not employed, high intensity π beam can be used, allowing us to take high statistics data of 100 times more than the previous experiments. We have proposed an experiment of Σp scattering at the K1.8 beam line by utilizing the K1.8 beam line spectrometer and the SKS spectrometer. A high intensity π beams of 2×107 /spill at 1.32 GeV/c and 1.42 GeV/c for the Σ- and Σ+ productions, respectively, are used to produce as many hyperon beam as possible.With 16×106 Σ- beam and 55×106 Σ+ beam around 500 MeV/c which are tagged by the spectrometers, we will detect ~10,000 Σ- p and Σ+ p scattering events and ~6,000 Σ- p → ⋀n inelastic reaction events in 60 days beam time in total. In this proceedings, we will present the experimental plan of the scattering experiment and results of the detailed simulation studies. [ABSTRACT FROM AUTHOR]- Published

We measured invariant mass spectra of e+e- pairs produced in 12-GeV p + A interaction to investigate in-medium mass modification of vector mesons. We observed the excess over the known hadronic sources below the ω meson mass peak. The obtained ρ/ω ratio and velocity dependence of excess/ω ratio imply that this excess mainly results from ρ meson whose mass was modified in nuclear matter. © 2004 American Institute of Physics [ABSTRACT FROM AUTHOR]

A hybrid emulsion experiment E373 at KEK has been carried out to study doubly strange nuclear system. By the 8% data analysis of all, one twin single-A hypernuclei event and two events of double-λ hypernucleus have been successfully detected. The twin single-A event is uniquely interpreted as ξ[sup -]+[sup 14]N → [sup 5, sub λ]He+ [sup 5, sub λ]He+[sup 4]He + n for the first time. In the first double-λ hypernucleus [sup 10, sub λλ]Be*)+t. The second double-event, "Demachi-Yanagi", it is interpreted as ξ[sup -]+[sup 12]C → [sup 10, sub λλ]Be( or A hypernucleus event, "NAGARA", shows a clearly recognized topology and the interpretation is uniqueas ξ[sup -]+[sups 12]C → [sup 6, sub λλ]He+[sup 4]He+t, [sup 6, sub λλ]He → [sup 5, sub λ]He+π[sup -]+p. [sup 5, sub λ]He → p+d+2n etc. By the preliminary result of the [sup 6, sub λλ]He, the attractive λλ interaction has been confirmed with the δB[sub λλ] ∼1 MeV. [ABSTRACT FROM AUTHOR]

- Abstract
Stopped-Ξ-12C reactions have been investigated with respect to H-dibaryon and hypernucleus formation with a scintillating fiber detector. Out of 5.5×103 tagged Ξ- particles via the (K-,K+) reaction we obtained 72 stopping Ξ- events with 6.7+1.1-1.4 background events after imposing kinematic constraints. Hypernuclear production has been studied by observing free Λ decays in the stopped-Ξ- reactions. From the observed Λ momentum spectrum, we have found the hypernuclear production rates to be 18±13, 65±6, and 17±12 % for double/twin-A hypernucleus, single-Λ hypernucleus, and no hypernucleus cases, respectively. With the same sample, we set upper limits on R (stopped-Ξ-12C→HX /stopped-Ξ-12C→ all) for H decaying into Λn, Σ-p, and Λpπ-, for H masses just below ΛΛ mass threshold and for H lifetime range 10-11≤τH≤10-8 s. The upper limits on R are ∼0.1-0.2, assuming all of the H decay into each decay mode. Our results give a tight constraint on the existence of the bound H, in comparison with the theoretical estimates of Aerts and Dover, albeit with different target nuclei.
