TL;DR: The branching fraction ratios in different four-momentum transfer square regions are examined, and find no significant deviations from the standard model predictions.
Abstract: Using a data sample corresponding to an integrated luminosity of 2.93 fb(-1) taken at a center-of-mass energy of 3.773 GeV with the BESIII detector operated at the BEPCII collider, we perform an analysis of the semileptonic decays D0(+) -> pi(-(0))mu(+)nu(mu ). The branching fractions of D-0 -> pi(-)mu(+)nu(mu), and D+ -> pi(0)mu(+)nu(mu ) are measured to be (0.272 +/- 0.008(start) +/- 0.006(syst))% and (0.350 +/- 0.011(star) +/- 0.010(syst))%, respectively, where the former is of much improved precision compared to previous results and the latter is determined for the first time. Using these results along with previous BESIII measurements of D0(+) -> pi(-(0))e(+)nu(e), we calculate the branching fraction ratios to be R-0 BD0 -> pi(-)mu(+)nu mu BD0 -> pi(-)e(+)nu e=0.922 +/- 0.030(start) +/- 0.022(syst) and R+ BD+ -> pi(0)mu(+)nu mu/BD+ -> pi(0)e(+)nu e= 0.964 +/- 0.037(start) +/- 0.026(syst), which arc compatible with the theoretical expectation of lepton flavor universality within 1.7 sigma and 0.5 sigma, respectively. We also examine the branching fraction ratios in different four-momentum transfer square regions, and find no significant deviations from the standard model predictions.

TL;DR: In this article, the decay dynamics of η'}→γπ+}π^{-} are studied with both model-dependent and model-independent approaches, and the contributions of ω and the ρ(770)-ω interference are observed for the first time in the decays η''}→ γπ+''π''-} in both approaches.
Abstract: Using a low background data sample of 9.7×10^{5} J/ψ→γη^{'}, η^{'}→γπ^{+}π^{-} events, which are 2 orders of magnitude larger than those from the previous experiments, recorded with the BESIII detector at BEPCII, the decay dynamics of η^{'}→γπ^{+}π^{-} are studied with both model-dependent and model-independent approaches. The contributions of ω and the ρ(770)-ω interference are observed for the first time in the decays η^{'}→γπ^{+}π^{-} in both approaches. Additionally, a contribution from the box anomaly or the ρ(1450) resonance is required in the model-dependent approach, while the process specific part of the decay amplitude is determined in the model-independent approach.

15 May 2018TL;DR: The results elaborated that the enhanced photocatalyticactivity was mainly attributed to the synergetic effect of Pt/ZnO and BiOI/ ZnO interfaces, indicating that the effective interfaces design is very important for the degradation of phenol in the preparation process of ternary hybrid photocatalyst.
Abstract: In this work, the ternary hybrid photocatalyst composed of ZnO nanorods with BiOI and Pt NPs (denoted as Pt@BiOI/ZnO) was fabricated by a simple three-step method. The as-prepared samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV–Vis diffuse reflectance spectrometry (DRS) and X-ray photoelectron spectroscopy (XPS), which proved the strong interaction has occurred among the Pt, BiOI and ZnO. The phenol degradation test showed that the Pt@BiOI/ZnO ternary hybrid composite exhibited the maximum photodegradation efficiency of phenol (99.9%) under UV irradiation within 30 min compared to Pt/BiOI, BiOI/ZnO binary composites as well as Pt/ZnO. Additionally, the transient photovoltage (TPV), steady-state PL spectra and time-resolved PL spectra were used to investigate the possible mechanism for photocatalytic performance. Our results elaborated that the enhanced photocatalytic activity was mainly attributed to the synergetic effect of Pt/ZnO and BiOI/ZnO interfaces. Conversely, the interfacial interaction of Pt/BiOI is little contribution, indicating that the effective interfaces design is very important for the degradation of phenol in the preparation process of ternary hybrid photocatalyst. These findings will contribute to developing high efficiency photocatalysts for application in environmental remediation.
