Direct X(3872) production in e+e- collisions

Direct production of the charmonium-like state $X(3872)$ in $e^+e^-$ collisions is considered in the framework of the vector meson dominance model. An order-of-magnitude estimate for the width $\Gamma(X\to e^+e^-)$ is found to be $\gtrsim$0.03 eV. The same approach applied to the $\chi_{c1}$ charmonium decay predicts the corresponding width of the order 0.1 eV in agreement with earlier estimates. Experimental perspectives for the direct production of the $1^{++}$ charmonia in $e^+e^-$ collisions are briefly discussed.Comment: LaTeX2e, 11 pages, 1 figure, version published in Phys.Lett.

The Reaction 7Li(pi+,pi-)7B and its Implications for 7B

The reaction 7Li(pi+,pi-)7B has been measured at incident pion energies of 30-90 MeV. 7Li constitutes the lightest target nucleus, where the pionic charge exchange may proceed as a binary reaction to a discrete final state. Like in the Delta-resonance region the observed cross sections are much smaller than expected from the systematics found for heavier nuclei. In analogy to the neutron halo case of 11Li this cross section suppression is interpreted as evidence for a proton halo in the particle-unstable nucleus 7B.Comment: 4 pages, 4 figure

Search for the Hypothetical pi -> mu x Decay

The KARMEN collaboration has reported the possible observation of a hitherto unknown neutral and weakly interacting particle x, which is produced in the decay pi -> mu + x with a mass m(x) = 33.9 MeV. We have searched for this hypothetical decay branch by studying muons from pion decay in flight with the LEPS spectrometer at the piE3 channel at PSI and find branching ratios BR(pi- to mu- anti-x) < 4e-7 and BR(pi+ to mu+ x) < 7e-8 (95\% C.L.). Together with the limit BR > 2e-8 derived in a recent theoretical paper our result would leave only a narrow region for the existence of x if it is a heavy neutrino.Comment: 10 pages, TeX (uses epsf), 3 Postscript figures uu-encode

Constraining the Hadronic Contributions to the Muon Anomalous Magnetic Moment

The mini-proceedings of the Workshop on "Constraining the hadronic contributions to the muon anomalous magnetic moment" which included the "13th meeting of the Radio MonteCarLow WG" and the "Satellite meeting R-Measurements at BES-III" held in Trento from April 10th to 12th, 2013, are presented. This collaboration meeting aims to bring together the experimental e+e- collider communities from BaBar, Belle, BESIII, CMD2, KLOE, and SND, with theorists working in the fields of meson transitions form factors, hadronic contributions to (g-2)_\mu and effective fine structure constant, and development of Monte Carlo generator and Radiative Corrections for precision e+e- and tau physics.Comment: 45 pages, 17 contributions.

Modifiable Factors Associated with Non-adherence to Antihypertensive or Antihyperlipidemic Drugs Are Dissimilar:a Multicenter Study Among Patients with Diabetes in Indonesia

Background To develop targeted and tailored interventions for addressing medication non-adherence, it is important to identify underlying factors. Objective To identify factors associated with non-adherence as well as subtypes of non-adherence to antihypertensive or antihyperlipidemic drugs among patients with type 2 diabetes in Indonesia. Design An observational multicenter cross-sectional survey. Participants Patients with type 2 diabetes using either antihypertensive or antihyperlipidemic drugs in four regions in Indonesia. Main Measures Non-adherence and its subtypes of intentional and unintentional non-adherence were assessed using the Medication Adherence Report Scale. Necessity and concern beliefs were assessed with the Beliefs about Medicines Questionnaire. We applied binary and multinomial logistic regression to assess associations of medication beliefs, sociodemographic factors, and clinical-related factors to non-adherence and report odds ratios (OR) with 95% confidence intervals (CI). Key Results Of 571 participating patients (response rate 97%), 45.5% and 52.7% were non-adherent to antihypertensive and antihyperlipidemic drugs, respectively. Older age was associated with non-adherence to antihypertensive drugs (60-69 years) (OR, 5.65; 95% CI, 2.68-11.92), while higher necessity beliefs (OR, 0.92; 95% CI, 0.88-0.95) were associated with less non-adherence. Factors associated with non-adherence to antihyperlipidemic drugs were female gender (OR, 1.84; 95% CI, 1.03-3.27) and higher concern beliefs (OR, 1.10; 95% CI, 1.03-1.18), while higher necessity beliefs (OR, 0.89; 95% CI, 0.83-0.96) were associated with less non-adherence. Conclusions The main factors associated with non-adherence to antihypertensive and antihyperlipidemic drugs are modifiable. In general, beliefs about the necessity of the drug are important but for antihyperlipidemic drugs concerns are important as well. Healthcare providers should pay attention to identify and address medication beliefs during patient counselling

Emotional Distress is Associated with Lower Health-Related Quality of Life Among Patients with Diabetes Using Antihypertensive and/or Antihyperlipidemic Medications:A Multicenter Study in Indonesia

Objective: To evaluate the associations between different types of diabetes distress and health-related quality of life (HRQOL) among patients with type 2 diabetes (T2DM) using antihypertensive and/or antihyperlipidemic medications in Indonesia and to explore the differences between those using only antihypertensive, only antihyperlipidemic, or both medications. Methods: A multicenter cross-sectional study was conducted in Community Health Centers in three cities in Indonesia among patients with T2DM aged at least 18 years who were using antihypertensive and/or antihyperlipidemic medications. Diabetes distress subscales (emotional, regimen-related, interpersonal, and physician-related distress) and HRQOL were assessed using a validated diabetes distress scale-17 and EQ-5D-5L scale, respectively. Multiple linear regression models were used to evaluate the associations between different types of diabetes distress and HRQOL adjusting for confounders. Results: Most of the 503 participants were females (67.6%) and aged 60-69 years (40.8%). Emotional distress was negatively associated with HRQOL among the whole group of patients (β: -0.08; 95% confidence interval (CI): -0.10, -0.05; p < 0.001). This association was similar across all therapeutic subgroups. Regimen-related distress (β: -0.06; 95% CI: -0.09, -0.03; p < 0.001) and interpersonal distress (β: -0.02; 95% CI: -0.05, -0.01; p = 0.022) were negatively associated, whereas physician-related distress (β: 0.04; 95% CI: 0.01, 0.07; p = 0.037) was positively associated with HRQOL among the whole group. These associations were also observed among those using only antihypertensive medication. Conclusion: Emotional distress affects HRQOL in T2DM patients treated for cardiovascular comorbidities, independent of antihypertensive and/or antihyperlipidemic medication use

Search for Light Gauge Bosons of the Dark Sector at the Mainz Microtron

A new exclusion limit for the electromagnetic production of a light U(1) gauge boson {\gamma}' decaying to e^+e^- was determined by the A1 Collaboration at the Mainz Microtron. Such light gauge bosons appear in several extensions of the standard model and are also discussed as candidates for the interaction of dark matter with standard model matter. In electron scattering from a heavy nucleus, the existing limits for a narrow state coupling to e^+e^- were reduced by nearly an order of magnitude in the range of the lepton pair mass of 210 MeV/c^2 < m_e^+e^- < 300 MeV/c^2. This experiment demonstrates the potential of high current and high resolution fixed target experiments for the search for physics beyond the standard model.Comment: 4 pages, 7 figure
