Gamma-ray spectroscopy of single Λ-hypernuclei at J-PARC: Results and perspective

Takeshi Koike, M. Agnello, J. K. Ahn, Y. Akazawa et autres

Experimental results from the J-PARC E13 experiments are summarized. A new experimental set up of E13 has established a platform for the future γ-ray hypernuclear spectroscopy at J-PARC using kaon beams. New γ rays are identified in HeΛ4 and FΛ19. The energy …

Missing-mass spectroscopy with the Li6(π−,K+)X reaction to search for HΛ6

R. Honda, M. Agnello, J. K. Ahn, S. Ajimura et autres

Hypernuclei, in which a proton or neutron in an atomic nucleus is replaced by a baryon that includes some number of valence strange quarks, are a unique probe of nuclear structure as well as of the strong interaction. This work provides significantly …

The New Stage Of S = -2 Hypernuclear Study Opened With A New High-resolution Spectrometer

Shunsuke Kanatsuki, Nobuaki Amano, H. Ekawa, T. Nanamura et autres

Spectroscopy of strangeness −2 systems has not been greatly in progress, because of the limited K− beam intensity to produce such systems and the limited energy resolution to identify them. Increasing K− beam intensity at J-PARC will enable us to carry out …

Observation of Spin-Dependent Charge Symmetry Breaking in Λ N Interaction: Gamma-Ray Spectroscopy of He Λ 4

Takeshi O. Yamamoto, M. Agnello, Y. Akazawa, Nobuaki Amano et autres

The energy spacing between the spin-doublet bound state of _{Λ}^{4}He(1^{+},0^{+}) was determined to be 1406±2±2 keV, by measuring γ rays for the 1^{+}→0^{+} transition with a high efficiency germanium detector array in coincidence with the ^{4}He(K^{-},π^{-})_{Λ}^{4}He reaction at J-PARC. In comparison to …
