Precision measurement of the 3d->2p x-ray energy in kaonic <sup>4</sup>He
Okada, S.,Beer, G.,Bhang, H.,Cargnelli, M.,Chiba, J.,Choi, S.,Curceanu, C.,Fukuda, Y.,Hanaki, T.,Hayano, R.S.,Iio, M.,Ishikawa, T.,Ishimoto, S.,Ishiwatari, T.,Itahashi, K.,Iwai, M.,Iwasaki, M.,Juhasz, North-Holland Pub. Co 2007 Physics letters: B Vol.653 No.5
We have measured the Balmer-series x-rays of kaonic <SUP>4</SUP>He atoms using novel large-area silicon drift x-ray detectors in order to study the low-energy K@?-nucleus strong interaction. The energy of the 3d->2p transition was determined to be 6467+/-3(stat)+/-2(syst) eV. The resulting strong-interaction energy-level shift is in agreement with theoretical calculations, thus eliminating a long-standing discrepancy between theory and experiment.

<P><B>Abstract</B></P><P>We have simultaneously measured the energy spectra of neutrons and protons emitted in the non-mesonic weak decays of HeΛ5 and CΛ12 hypernuclei produced via the (<SUP>π+</SUP>,<SUP>K+</SUP>) reaction with much higher statistics than those of previous experiments. The neutron-to-proton yield ratios for both hypernuclei at a high energy threshold (60 MeV) were approximately equal to two, which suggests that the ratio of the neutron- and proton-induced decay channels, <SUB>Γn</SUB>(Λn→nn)/<SUB>Γp</SUB>(Λp→np), is about 0.5. In the neutron energy spectra, we found that the yield of the low-energy component is unexpectedly large, even for HeΛ5.</P>

Contribution of a Non-classical HLA Gene, HLA-DOA, to the Risk of Rheumatoid Arthritis

<P>Despite the progress in human leukocyte antigen (HLA) causal variant mapping, independent localization of major histocompatibility complex (MHC) risk from classical HLA genes is challenging. Here, we conducted a large-scale MHC fine-mapping analysis of rheumatoid arthritis (RA) in a Japanese population (6,244 RA cases and 23,731 controls) population by using HLA imputation, followed by a multi-ethnic validation study including east Asian and European populations (n=7,097 and 23,149, respectively). Our study identified an independent risk of a synonymous mutation at HLA-DOA, a non-classical HLA gene, on anti-citrullinated protein autoantibody (ACPA)-positive RA risk (p=1.4 x 10(-) 9), which demonstrated a cis-expression quantitative trait loci (cis-eQTL) effect on HLA-DOA expression. Trans-ethnic comparison revealed different linkage disequilibrium (LD) patterns in HLA-DOA and HLA-DRB1, explaining the observed HLA-DOA variant risk heterogeneity among ethnicities, which was most evident in the Japanese population. Although previous HLA fine-mapping studies have identified amino acid polymorphisms of the classical HLA genes as driving genetic susceptibility to disease, our study additionally identifies the dosage contribution of a non-classical HLA gene to disease etiology. Our study contributes to the understanding of HLA immunology in human diseases and suggests the value of incorporating additional ancestry in MHC fine-mapping.</P>

<P><B>Abstract</B></P><P>We have measured the proton energy distribution from the <SUP>4</SUP>He(stopped <SUP>K−</SUP>,p) reaction by means of time-of-flight. A mono-energetic peak was observed, which is interpreted as the formation of a new kind of neutral tribaryon S<SUP>0</SUP>(3115) with isospin T=1 and strangeness S=−1. The mass and width of the state were deduced to be 3117.0−4.4+1.5MeV/<SUP>c2</SUP> and <21MeV/<SUP>c2</SUP>, respectively. The state mainly decays into ΣNN.</P>
