Abstract

The nuclear emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS of 27 GeV average neutrino energy from 1994 to 1997. In total about 100000 charged-current neutrino interactions with at least one identified muon were located in the emulsion target and fully reconstructed, using newly developed automated scanning systems. Charmed particles were searched for by a program recognizing particle decays. The observation of the decay in nuclear emulsion makes it possible to select a sample with very low background and minimal kinematical bias. 2013 charged-current interactions with a charmed hadron candidate in the final state were selected and confirmed through visual inspection. The charm production rate induced by neutrinos relative to the charged-current cross-section is measured to be sigma(nu_mu N -> mu- C X)/sigma(CC) = (5.75 +-0.32 stat +-0.30 syst)%. The charm production cross-section as a function of the neutrino energy is also obtained. The results are in good agreement with previous measurements. The charm-quark hadronization produces the following charmed hadrons with relative fractions (in %): f_Dzero = 43.7+-4.5, f_Lambda_c^plus = 19.2+-4.2, f_Dplus = 25.3+-4.2, and f_D_splus = 11.8+-4.7., Comment: 16 pages, 5 figures

Abstract

We report a measurement of the neutrino-electron elastic scattering rate from 8B solar neutrinos based on a 123 kton-day exposure of KamLAND. The background-subtracted electron recoil rate, above a 5.5 MeV analysis threshold is 1.49+/-0.14(stat)+/-0.17(syst) events per kton-day. Interpreted as due to a pure electron flavor flux with a 8B neutrino spectrum, this corresponds to a spectrum integrated flux of 2.77+/-0.26(stat)+/-0.32(syst) x 10^6 cm^-2s^-1. The analysis threshold is driven by 208Tl present in the liquid scintillator, and the main source of systematic uncertainty is due to background from cosmogenic 11Be. The measured rate is consistent with existing measurements and with Standard Solar Model predictions which include matter enhanced neutrino oscillation., Comment: 6 pages, 3 figures

Abstract

Ground-state electric quadrupole moment of 31Al (I =5/2+, T_1/2 = 644(25) ms) has been measured by means of the beta-NMR spectroscopy using a spin-polarized 31Al beam produced in the projectile fragmentation reaction. The obtained Q moment, |Q_exp(31Al)| = 112(32)emb, are in agreement with conventional shell model calculations within the sd valence space. Previous result on the magnetic moment also supports the validity of the sd model in this isotope, and thus it is concluded that 31Al is located outside of the island of inversion., Comment: 5 pages

13. Cross-cultural affective neuroscience personality comparisons of Japan, Turkey and Germany

Abstract

Mothering styles and family models of different cultures- that vary in interdependency and independency combinations—can influence the development of basic affects differently. The present study carried out the cross-cultural comparisons of samples from Japan, Turkey and Germany on self-construals, basic affects and Big Five factors. The countries were selected along a Euro-Asian spectrum, from highly collectivistic Japan to least collectivistic Germany, with Turkey as a bridging culture. The sample consisted of undergraduate and graduate students from Kyoto in Japan (n= 353), Istanbul in Turkey (n= 327) and Bonn in Germany (n= 222). The questionnaire included the self-construal scale (SCS), the affective neuroscience personality scales (ANPS) and the big five scale (B5S). SCS scores showed that the level of interdependent self-construals decreased from East to West, but independent self-construals did not gradually increase. Highest independency score was found in Turkey. Theoretically well-known German individualism was not found to be based on higher independency, but on lower interdependency. On ANPS, female groups seemed very similar on positive affects whereas for negative affects they had differences; like Japanese females had higher FEAR, Turkish females had higher ANGER. Similarly, Japanese males had higher FEAR and SADNESS, Turkish males had higher ANGER. On ANPS, Turkish and Japanese males were more similar and distinct from the German males who had lower scores almost on all affects. However on B5S; Turks and Germans were found to be quite similar and distinct from the Japanese. Turkey seemed to maintain more subcortical affective personality similarities with Japan, while attuning more to B5 factors displayed by Germany. Findings are discussed in light of child-rearing styles in each country.
