JHEP 02 (2013) 098 We search for CP violation in the decay $D^+\rightarrow K^0_S K^+$ using a
data sample with an integrated luminosity of 977 fb$^{-1}$ collected with the
Belle detector at the KEKB ...$e^+e^-$ asymmetric-energy collider. No CP violation
has been observed and the CP asymmetry in $D^+\rightarrow K^0_S K^+$ decay is
measured to be $(-0.25\pm0.28\pm0.14)%$, which is the most sensitive
measurement to date. After subtracting CP violation due to $K^0-\bar{K}^0$
mixing, the CP asymmetry in $D^+\rightarrow\bar{K}^0 K^+$ decay is found to be
$(+0.08\pm0.28\pm0.14)%$.
We present a measurement of the branching fraction and time-dependent CP violation parameters in B0 --> a_1^+-(1260) pi^-+ decays. The results are obtained from the final data sample containing ...772x10^6 BBbar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^+e^- collider. We also measure an upper limit on the product branching fraction for a possible decay with the same final state B0 --> a_2^+-(1320) pi^-+. In a time-dependent measurement to extract CP asymmetries, we find evidence of mixing-induced CP violation in B0 --> a_1^+-(1260) pi^-+ decays with a 3.1 sigma significance and the rate where the a_1^+-(1260) does not contain the spectator quark is found to dominate the rate where it does at the 4.1 sigma level. However, there is no evidence for either time and flavor integrated direct CP violation or flavor-dependent direct CP violation.
We report a search for a dark vector gauge boson \(U^\prime\) that couples to quarks in the decay chain \(D^{*+} \to D^0 \pi^+, D^0 \to K^0_S \eta, \eta \to U^\prime \gamma\), \(U^\prime \to \pi^+ ...\pi^-\). No signal is found and we set a mass-dependent limit on the baryonic fine structure constant of \(10^{-3} - 10^{-2}\) in the \(U^\prime\) mass range of 290 to 520 MeV/\(c^2\). This analysis is based on a data sample of 976 fb\(^{-1}\) collected by the Belle experiment at the KEKB asymmetric-energy \(e^+e^-\) collider.
We report a measurement of the inclusive semileptonic $B_s^0$ branching
fraction in a $121~fb^{-1}$ data sample collected near the $\Upsilon(5S)$
resonance with the Belle detector at the KEKB ...asymmetric energy $e^+ e^-$
collider. Events containing $B_s^0$ pairs are selected by reconstructing a tag
side $D_s^+$ and identifying a signal side lepton $\ell^+$ ($\ell = e, \mu$)
that is required to have the same-sign charge to ensure that both originate
from different $B_s^0$ mesons. The $B_s^0 \rightarrow X^- \ell^+ \nu_\ell$
branching fraction is extracted from the ratio of the measured yields of
$D_s^+$ mesons and $D_s^+ \ell^+$ pairs and the known production and branching
fractions. The inclusive semileptonic branching fraction is measured to be
$9.6 \pm 0.4\text{(stat)} \pm 0.7\text{(syst)}~\%$.
La pancréatite aiguë est une complication rare au cours de la grossesse. Les causes sont dominées par les lithiases des voies biliaires et les dyslipidémies. Parmi les autres causes, l’hypertension ...artérielle gravidique a été exceptionnellement décrite. Nous rapportons un cas de pancréatite aiguë grave chez une femme âgée de 35 ans dans les suites d’une toxémie gravidique sévère. Le diagnostic de pancréatite aiguë a été évoqué devant des douleurs abdominales. La scanographie abdominale avec injection a montré une pancréatite stade E. L’origine lithiasique a été éliminée par deux échographies abdominales. Une hyperlipidémie a été éliminée devant un bilan lipidique normal. L’évolution a été défavorable et la patiente est décédée dans un tableau de défaillance multiviscérale.
The acute pancreatitis is a rare complication during the pregnancy. Causes are dominated by the gallstones and hyperlipidemia. This case report describes a 35-year-old pregnant woman who developed acute pancreatitis while suffering from a severe pre-eclampsia syndrome. Since she had no gallstones or other known aetiological factors of acute pancreatitis, the possibility of an etiologic role of pancreatic ischaemic changes associated with eclampsia is discussed. Evolution was marked with multi-organ system failure and poor outcome. Our experience and the previously reported case suggest that pre-eclampsia could be added to the list of causes of the acute pancreatitis.
