High-resolution search for the $I^^{+}$ pentaquark via a pion-induced reaction at J-PARC

PARC E19 Collaboration, M. Moritsu, S. Adachi +72

The pentaquark $I^^{+}$ has been searched for via the $I ¨ ^{-} p \to K^{-} X$ reaction with beam momenta of 1.92 and 2.01 GeV/ $c$ at J-PARC. A missing mass resolution of 2 MeV (FWHM) was ac…

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

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

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

Observation of Coulomb-assisted nuclear bound state of $I^^{-}$ - $^{14}$ N system

S. H. Hayakawa, K. Agari, J. K. Ahn +95

In an emulsion-counter hybrid experiment performed at J-PARC, a $I^^{-}$ absorption event was observed which decayed into twin single- $I^$ hypernuclei. Kinematic calculations enabled…

Search for the $I^^{+}$ pentaquark via the $I ¨ ^{-} p \to K^{-} X$ reaction at 1.92 GeV/ $c$

K. Shirotori, T. N. Takahashi, S. Adachi +65

The $I^^{+}$ pentaquark baryon was searched for via the $I ¨ ^{-} p \to K^{-} X$ reaction in a missing-mass resolution of 1.4 MeV/ $c^{2}$ (FWHM) at J-PARC. $I ¨ ^{-}$ meson beams were incident on th…

Search for $_{I^}^{6} $ H hypernucleus by the $^{6}$ Li $(I ¨ ^{-}, K^{+})$ reaction at $p_{I ¨ ^{-}}$ = 1.2 GeV/ $c$

H. Sugimura, M. Agnello, J. K. Ahn +63

We have carried out an experiment to search for a neutron-rich hypernucleus, $_{I^}^{6} $ H, by the $^{6}$ Li( $I ¨ ^{-}, K^{+}$ ) reaction at $p_{I ¨ ^{-}}$ =1.2 GeV/ $c$ . The obtained missing mass spec…

Hypernuclear spectroscopy of products from 6Li projectiles on a carbon target at 2 AGeV

C. Rappold, E. Kim, D. Nakajima +50

A novel experiment, aiming at demonstrating the feasibility of hypernuclear spectroscopy with heavy-ion beams, was conducted. Using the invariant mass method, the spectroscopy of h…

Observation of a Be double-Lambda hypernucleus in the J-PARC E07 experiment

H. Ekawa, K. Agari, J. K. Ahn +100

A double- $I^$ hypernucleus, $_{I^ I^} Be$ , was observed by the J-PARC E07 collaboration in nuclear emulsions tagged by the $(K^{-}, K^{+})$ reaction. This event was interpr…

Test of a small prototype of the COMET cylindrical drift chamber

C. Wu, T. S. Wong, Y. Kuno +9

The performance of a small prototype of a cylindrical drift chamber (CDC) used in the COMET Phase-I experiment was studied by using an electron beam. The prototype chamber was cons…
