Using data taken at 29 center-of-mass energies between 4.16 and 4.70 GeV with the BESⅢ detector at the Beijing Electron Positron Collider corresponding to a total integrated luminosity of approximately 18.8 fb-1, the process e+e-→■+ c.c. is observed for the first time with a statistical significance of 11.5σ. The average Born cross sections in the energy ranges of（4.160, 4.380） GeV,（4.400, 4.600） GeV and（4.610, 4.700） GeV are measured to be（21.5±5.7±1.2） fb,（46.3±10.6±2.5） fb and （59.0±9.4±3.2） fb, respectively, where the first uncertainties are statistical and the second are systematic. The line shapes of the ■ and ppπ-invariant mass spectra are consistent with phase space distributions, indicating that no hexaquark or di-baryon state is observed.

Using 7.93 fb−1 of e+e− collision data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, we present an analysis of the decay D0→ηπ−e+νe. The branching fraction of the decay D0→a0(980)−e+νe with a0(980)−→ηπ− is measured to be (0.86±0.17stat±0.05syst)×10−4. The decay dynamics of this process is studied with a single-pole parametrization of the hadronic form factor and the Flatté formula describing the a0(980) line shape in the differential decay rate. The product of the form factor f+a0(0) and the Cabibbo-Kobayashi-Maskawa matrix element |Vcd| is determined for the first time with the result f+a0(0)|Vcd|=0.126±0.013stat±0.003syst.

Calibration of Interface Induced Polarization for Full Polarimetric Ground Penetrating Radar

引用

IOP Conference Series: Earth and Environmental science 2021年第1期660卷

作者： Zejun Dong Xuan Feng Cai Liu Wenjing Liang Haoqiu Zhou College of Geo-Exploration Science and Technology Jilin University No.938 Xi MinZhu Street Changchun China Science and Technology on Near-Surface Detection Laboratory Wuxi China Institute of National Development and Security Studies Jilin University No.2699 Qianjin Street Changchun China Key Laboratory of Geophysical Exploration Equipment Ministry of Education (Jilin University) No.938 Xi MinZhu Street Changchun China

The traditional ground penetrating radar (GPR) uses only one type of antenna for data acquisition, and only obtains single polarization data of targets. It can not fully describe the various properties of the target. Full polarimetric GPR is a new technology that uses four different polarization antennas to measure the target and can receive electromagnetic waves of different polarized directions to describe the polarization effect of targets. However, when the plane electromagnetic wave propagates through the ground surface, the polarized direction will rotate, namely interface induced polarization (IIP), which results in the complex interference embedded in the full polarimetric GPR data. In this research, firstly we discuss the generation of the IIP; subsequently how the IIP affect the full polarimetric GPR data is derived; finally the calibration formula is proposed and is applied to the GPR data processing.

Numerical Simulation of Subsurface Penetrating Radar in Isidis Planitia on Mars for China's First Mission to Mars

引用

IOP Conference Series: Earth and Environmental science 2021年第1期660卷

作者： Ying Wang Xuan Feng Wenjing Liang Haoqiu Zhou Zejun Dong Xiaotian Li Cewen Xue College of Geo-Exploration Science and Technology Jilin University No.938 Xi Min Zhu Street Changchun China Science and Technology on Near-Surface Detection Laboratory Wuxi China Institute of National Development and Security Studies Jilin University No.2699 Qianjin Street Changchun China Key Laboratory of Geophysical Exploration Equipment Ministry of Education (Jilin University) No.938 XiMin Zhu Street Changchun China

The water ice exploration mission is an important scientific target of China's first Mission to Mars. The high frequency full polarimetric subsurface penetrating radar (SPR) system onboard the landing rover can carry out high-resolution imaging of the near-surface area of Mars, which is an important tool for detecting the presence of shallow water ice and soil structure. At present, most of the radar detection simulations are based on low-frequency antennas to analyze the geological structure of Mars down to several kilometers, with low resolution, which is difficult to detect the subsurface structure in the near-surface accurately. Considering topographic relief, interface roughness, subsurface rock, water ice, and permittivity changes at different layers, a three-dimensional near-surface model in the Isidis Planitia on Mars is established. The interpretation of the forward simulation results is of reference value for future Mars exploration missions.

By analyzing 7.93 fb−1 of e+e− collision data collected at the center-of-mass energy of 3.773 GeV with the BESIII detector operated at the BEPCII collider, we report the observation of the semimuonic decays of D+→K¯1(1270)0μ+νμ and D0→K1(1270)−μ+νμ with statistical significances of 12.5σ and 6.0σ, respectively. Their decay branching fractions are determined to be B[D+→K¯1(1270)0μ+νμ]=(2.36±0.20−0.27+0.18±0.48)×10−3 and B[D0→K1(1270)−μ+νμ]=(0.78±0.11−0.09+0.05±0.15)×10−3, where the first and second uncertainties are statistical and systematic, respectively, and the third originates from the input branching fraction of K¯1(1270)0→K−π+π0 or K1(1270)−→K−π+π−. Combining our branching fractions with the previous measurements of B[D+→K¯1(1270)0e+νe] and B[D0→K1(1270)−e+νe], we determine the branching fraction ratios to be B[D+→K¯1(1270)0μ+νμ]/B[D+→K¯1(1270)0e+νe]=1.03±0.14−0.15+0.11 and B[D0→K1(1270)−μ+νμ]/B[D0→K1(1270)−e+νe]=0.74±0.13−0.13+0.08. Using the branching fractions measured in this work and the world-average lifetimes of the D+ and D0 mesons, we determine the semimuonic partial decay width ratio to be Γ[D+→K¯1(1270)0μ+νμ]/Γ[D0→K1(1270)−μ+νμ]=1.22±0.10−0.09+0.06, which is consistent with unity as predicted by isospin conservation.

Using a dedicated data sample taken in 2018 on the J/ψ peak, we perform a detailed study of the trigger efficiencies of the BESⅢ detector. The efficiencies are determined from three representative physics processes,namely Bhabha scattering, dimuon production and generic hadronic events with charged particles. The combined efficiency of all active triggers approaches 100% in most cases, with uncertainties small enough not to affect most physics analyses.

PCA applied to Data Fusion for Subsurface Target Imaging of Full-polarimetric GPR

IOP Conference Series: Earth and Environmental science 2021年第1期660卷

作者： Cewen Xue Xuan Feng Haoqiu Zhou Xiaotian Li Wenjing Liang Ying Wang College of Geo-Exploration Science and Technology Jilin University No.938 Xi MinZhu Street Changchun 130026 China Science and Technology on Near-Surface Detection Laboratory Wuxi 214035 China Institute of National Development and Security Studies Jilin University No.2699 Qianjin Street Changchun 130012 China Key Laboratory of Geophysical Exploration Equipment Ministry of Education (Jilin University) No.938 Xi MinZhu Street Changchun 130026 China

Full-polarimetric ground penetrating radar (GPR) can obtain more comprehensive polarization data (called VV, HH, VH) for the same target than traditional commercial radar (only VV). We need to use data fusion technology to combine the polarization information of the three different polarization modes. However, the full-polarimetric GPR data fusion method has one weighted average fusion, which will mask the advantages of full polarization. Principal component analysis (PCA) is a technology of data dimensionality reduction and compression which can use VV, HH and VH as a three-dimensional data to conduct data dimensionality reduction and find the best data fusion results. In order to check the reliability, we obtained the full-polarimetric GPR data of three typical targets in the laboratory for analysis. Then we compare PCA with the weighted average fusion method by using the instantaneous amplitude and conclude that PCA can fuse full-polarimetric GPR data better than weighted average fusion.

The warming season of Antarctica, where sea ice melts and breaks, is often the golden time for Antarctic research. But this season is also a high frequency season for the formation of ice crack, the existence of which poses a serious threat to Antarctic scientific research. Therefore, it is of important significance to monitor the trend, location, and depth of Antarctic sea ice crack in real time. Ice crack detection often uses ground penetrating radar (GPR) technology. Compared with the single-polarimetric GPR, full-polarimetric GPR can obtain more comprehensive polarization information. Therefore, a full-polarimetric GPR system based on the horn antenna is built in this paper to obtain more abundant ice crack information. Then we apply it to detect a small-scale ice crack atop frozen lakes. The analysis of the experiments and data fusion processing results can verify the effectiveness of the system for the detection of ice crack and lay the foundation for subsequent actual detection.

A possibility for one-step synthesis of bimetallic CuNi nanopowders in a different ratio of Ni to Cu by solution combustion synthesis technique under normal air atmosphere without any post reduction is reported. The effect of different types of fuels like citric acid and glycine on the combustion process and characteristics of resultant solid products were investigated. XRD results showed the existing of CuNi as a main phase and small amounts of CuO and (Ni,Cu)₄N. Determined CuNi particle sizes were in the range of up to 50 nm. Computer simulation was performed using the molecular dynamics method for similar concentration compositions, but in size range of 4.5–5.5 nm, as a result of cooling the system from 1700 K to 300 K. In addition, two types of melting scenario of binary CuNi NPs were studied: 1) heterogeneous melting of monocrystalline Cu and Ni NPs;2) melting of the crystallization products of binary NPs. Melting temperatures weakly depend on the choice of the above-mentioned melting scenario. However, the nature of subsequent crystallization can be influenced by the initial energy of the system, which is higher for case 1. The characteristic temperatures of phase transitions of melting and crystallization are determined based on the analysis of hysteresis loops of the specific potential part of the internal energy of NPs. The patterns of atomic and structural segregation in binary CuNi NPs were studied. © 2024 Elsevier B.V.
