First Determination of Level Structure of an $s d$ -Shell Hypernucleus, $_{Λ}^{19} F$

S. B. Yang, J. K. Ahn, Y. Akazawa +45

We report on the first observation of $γ$ rays emitted from an $s d$ -shell hypernucleus, $_{Λ}^{19} F$ . The energy spacing between the ground state doublet, $1/ 2^{+}$ and $3/ 2^{+}$ …

Photoproduction of $Λ$ and $Σ^{0}$ hyperons off protons with linearly polarized photons at $E_{γ} = 1.5 - 3.0$ GeV

S. H. Shiu, H. Kohri, W. C. Chang +42

We report the measurement of the $γ p \to K^{+} Λ$ and $γ p \to K^{+} Σ^{0}$ reactions at SPring-8. The differential cross sections and photon-beam asymmetries are meas…

First measurement of coherent $ϕ$ -meson photoproduction from helium-4 near threshold

LEPS Collaboration, T. Hiraiwa, M. Yosoi +42

The differential cross sections and decay angular distributions for coherent $ϕ$ -meson photoproduction from helium-4 have been measured for the first time at forward angles with li…

Differential cross section and photon beam asymmetry for the gamma p -> pi+ n reaction at forward pi+ angles at Egamma=1.5-2.95 GeV

H. Kohri, S. Y. Wang, S. H. Shiu +46

Differential cross sections and photon beam asymmetries for the gamma p -> pi+ n reaction have been measured for 0.6<cos(theta)<1 and Egamma=1.5-2.95 GeV at SPring-8/LEPS. The cros…

Missing-mass spectroscopy with the $^{6}$ Li( $π^{-}, K^{+}$ )X reaction to search for $_{Λ}^{6}$ H

R. Honda, M. Agnello, J. K. Ahn +63

We searched for the bound state of the neutron-rich $Λ$ -hypernucleus $_{Λ}^{6}$ H, using the $^{6}$ Li( $π^{-}, K^{+}$ )X double charge-exchange reaction at a $π^{-}$ beam momentum o…
