Impurity effect on low-temperature polarisation of the charge-density-waves in o-TaS3_3

The temperature dependence of the low-temperature dielectric response is studied in o-TaS$_3$ samples doped by Nb, Se, and Ni and for nominally pure ones. It is found, that the low-temperature dielectric constant depends anomalously on doping and is higher for doped crystals, whereas the temperature dependence of the characteristic time of all samples follows the activation law with nearly the same activation energy $\sim 400$ K (T>20 K). The observed behaviour is inconsistent with all available explanations of the low-temperature dielectric anomaly.Comment: RevTex, 12 pages, epsf, 2 postscript Figures.

Prevalence of Diseases Among Children Population in Dnepropetrovsk Region (Ukraine), Correlated with Deterioration of Drinking Water Quality

Цель исследования – изучение динамики распространённости заболеваний среди детского населения сельских таксонов области и корреляционный анализ показателей качества питьевой воды с некоторыми показателями распространённости болезней. Изучено общее количество (522720 показателей) распространённости болезней среди детей в 6 типах таксонов Днепропетровской области (Украина) за 2008-2013 гг. Доказано, что болезни I, II, III, XI, XIII, XIV классов являются приоритетными по распространенности в большинстве сельских таксонов. Показана корреляционная связь между повышенным солевым составом питьевой воды из децентрализованных источников, содержанием отдельных тяжёлых металлов (Zn, Cu, Mn) и некоторыми веществами (pH, F, Al, азот аммиака, нитриты, нитраты, окисляемость) с распространённостью среди детей новообразований (r=0,87); болезней крови и органов кроветворения (r=0,74–0,95); анемии (r=0,79-0,87); болезней мочеполовой системы (r=0,79- 0,82); врожденных аномалий (r=0,87), в том числе системы кровообращения (r=0,74-0,95) в некоторых таксонах Днепропетровской области (p<0,001). Purpose of research was to study dynamics prevalence of diseases among children’ population in the separate rural tacsons of Dnepropetrovsk region; to carry out correlation analysis between some indicators of drinking water quality and prevalence of diseases. Research indicators of prevalence of diseases was carried out in the 6 types of tacsons of Dnipropetrovsk region (Ukraine) during 2008 – 2013 years (totally 522720 indicators). It was proved that (I, II, III, XI, XIII, XIV) classes of diseases takes the ｸrst place by the prevalence of diseases in the majority of rural tacsons. Correlation between higher salt content of the potable water taking from decentralized sources and content of some heavy metals (Zn, Cu, Mn) and some substances (pH, F, Al, nitrogen ammonia, nitrites, nitrates, oxidability) and the prevalence of diseases among children: tumors (r=0.87); diseases of blood and hematopoetic organs (r=0.74–0.95); anemia (r=0.79–0.87); diseases of genitourinary system (r=0.79–0.82); congenital anomalies (r=0.87), including circulatory system (r=0.74–0.95) was revealed in the separate tacsons of Dnepropetrovsk region (p<0.001)

High-statistics measurement of the pion form factor in the rho-meson energy range with the CMD-2 detector

We present a measurement of the pion form factor based on e+e- annihilation data from the CMD-2 detector in the energy range 0.6<sqrt(s)<1.0 GeV with a systematic uncertainty of 0.8%. A data sample is five times larger than that used in our previous measurement.Comment: 18 pages, 10 figures. Added comparison with KLOE measurement, minor updates. Accepted by PL

Measurement of ϕ\phi(1020) meson leptonic width with CMD-2 detector at VEPP-2M Collider

The $\phi$(1020) meson leptonic width has been determined from the combined analysis of 4 major decay modes of the resonance ($\phi\to K^+ K^-,K^0_LK^0_S,\pi^+\pi^-\pi^0,\eta\gamma$) studied with the CMD-2 detector at the VEPP-2M $e^+e^-$ collider. The following value has been obtained: $\Gamma(\phi\to e^+e^-) = 1.235\pm 0.006\pm 0.022$ keV. The $\phi(1020)$ meson parameters in four main decay channels have been also recalculated: $B(\phi\to K^+K^-) = 0.493\pm 0.003\pm 0.007$, $B(\phi\to K_LK_S) = 0.336\pm 0.002\pm 0.006$, $B(\phi\to\pi^+\pi^-\pi^0) = 0.155\pm 0.002\pm 0.005$, $B(\phi\to\eta\gamma) = 0.0138\pm 0.0002\pm 0.0002$.Comment: 14 pages, 3 figure

Study of the Process e+ e- --> omega pi0 --> pi0 pi0 gamma in c.m. Energy Range 920--1380 MeV at CMD-2

The cross section of the process e+ e- --> omega pi0 --> pi0 pi0 gamma has been measured in the c.m. energy range 920-1380 MeV with the CMD-2 detector. Its energy dependence is well described by the interference of the rho(770) and rho'(1450) mesons decaying to omega pi0. Upper limits for the cross sections of the direct processes e+ e- --> pi0 pi0 gamma, eta pi0 gamma have been set.Comment: Accepted for publication in PL

Study of the Process e+ e- --> pi0 pi0 gamma in c.m. Energy Range 600--970 MeV at CMD-2

The cross section of the process e+ e- --> pi0 pi0 gamma has been measured in the c.m. energy range 600--970 MeV with the CMD-2 detector. The following branching ratios have been determined: B(rho --> pi0 pi0 gamma) =(5.2^{+1.5}_{-1.3} +- 0.6)x10^{-5} and B(omega --> pi0 pi0 gamma) =(6.4^{+2.4}_{-2.0} +- 0.8)x10^{-5}. Evidence for the rho --> f0(600) gamma decay has been obtained: B(rho --> f0(600) gamma) = (6.0^{+3.3}_{-2.7}\pm 0.9)x10^{-5}. From a search for the process e+ e- --> eta pi0 gamma the following upper limit has been obtained: B(omega --> eta pi0 gamma) < 3.3 10^{-5} at 90% CL.Comment: 15 pages, 4 figure

Search for composite and exotic fermions at LEP 2

A search for unstable heavy fermions with the DELPHI detector at LEP is reported. Sequential and non-canonical leptons, as well as excited leptons and quarks, are considered. The data analysed correspond to an integrated luminosity of about 48 pb^{-1} at an e^+e^- centre-of-mass energy of 183 GeV and about 20 pb^{-1} equally shared between the centre-of-mass energies of 172 GeV and 161 GeV. The search for pair-produced new leptons establishes 95% confidence level mass limits in the region between 70 GeV/c^2 and 90 GeV/c^2, depending on the channel. The search for singly produced excited leptons and quarks establishes upper limits on the ratio of the coupling of the excited fermio

Search for lightest neutralino and stau pair production in light gravitino scenarios with stau NLSP

Promptly decaying lightest neutralinos and long-lived staus are searched for in the context of light gravitino scenarios. It is assumed that the stau is the next to lightest supersymmetric particle (NLSP) and that the lightest neutralino is the next to NLSP (NNLSP). Data collected with the Delphi detector at centre-of-mass energies from 161 to 183 \GeV are analysed. No evidence of the production of these particles is found. Hence, lower mass limits for both kinds of particles are set at 95% C.L.. The mass of gaugino-like neutralinos is found to be greater than 71.5 GeV/c^2. In the search for long-lived stau, masses less than 70.0 to 77.5 \GeVcc are excluded for gravitino masses from 10 to 150 \eVcc . Combining this search with the searches for stable heavy leptons and Minimal Supersymmetric Standard Model staus a lower limit of 68.5 \GeVcc may be set for the stau mas
