Search for Theta+ via K+p -> pi+X reaction with a 1.2 GeV/c K+ beam
The Theta+ was searched for via the K+p -> pi+X reaction using the 1.2 GeV/c
K+ beam at the K6 beam line of the KEK-PS 12 GeV Proton Synchrotron. In the
missing mass spectrum of the K+p -> pi+X reaction, no clear peak structure was
observed. Therefore a 90 % C.L. upper limit of 3.5 ub/sr was derived for the
differential cross section averaged over 2degree to 22degree in the laboratory
frame of the K+p -> pi+Theta+ reaction. This upper limit is much smaller than
the theoretical calculation for the t-channel process where a K0* is exchanged.
From the present result, either the t-channel process is excluded or the
coupling constant of g_{K*N\Theta} is quite small.Comment: 11pages, 13figure

Natural larval Echinococcus multilocularis infection in a Norway rat, Rattus norvegicus, captured indoors in Hokkaido, Japan
Natural infection with larval Echinococcus multilocularis was recognized in one of eight Norway rats, Rattus norvegicus, caught indoors in 2009 in Ebetsu, Hokkaido, northern Japan. Cystic lesions were found in the right median and lateral lobes of the liver, with numerous alveolar cysts in the periphery of the lesions. Protoscolices were formed within large cysts. The laminated layers of the cysts were positive for PAS staining. Nested PCR using the primers specific for Taenia mitochondrial 12S rDNA yielded a 250-bp product, and the sequence of the PCR product matched that of E. multilocularis isolates from Hokkaido and Germany. This is the third natural alveolar hydatidosis in R. norvegicus in Japan
