There has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics. This renaissance has been driven in part by the discovery of a plethora of charmonium-like xyz states at bEsⅢ and b factories, and the observation of an intriguing proton-antiproton threshold enhancement and the possibly related x(1835) meson state at bEsⅢ, as well as the threshold measurements of charm mesons and charm baryons. we present a detailed survey of the important topics in tau-charm physics and hadron physics that can be further explored at bEsⅢ during the remaining operation period of bEPCⅡ. This survey will help in the optimization of the data-taking plan over the coming years, and provides physics motivation for the possible upgrade of bEPCⅡ to higher luminosity.

目的收集并分析ChINET中国细菌耐药性监测网中5种重要临床分离菌的耐药性变迁。方法采用纸片扩散法或自动化仪器法按统一方案进行药物敏感性试验。按CLsI 2014年版标准判断结果。结果 2005—2014年,每年的临床分离菌数量为22 774~84 572株。大肠埃希菌中产EsbL菌株检出率为51.7%~55.8%。在上述时期内大肠埃希菌和肺炎克雷伯菌对阿米卡星、环丙沙星、哌拉西林-他唑巴坦和头孢哌酮-舒巴坦的耐药率有所下降。肺炎克雷伯菌中碳青霉烯类耐药株由2.4%上升至13.4%。铜绿假单胞菌对包括亚胺培南和美罗培南的所有受试抗菌药物的耐药率均有所下降。鲍曼不动杆菌对碳青霉烯类的耐药率由31.0%逐步上升至66.7%。耐甲氧西林金黄色葡萄球菌的检出率由2005年的69%逐年下降至2014年的44.6%。结论国内肺炎克雷伯菌和鲍曼不动杆菌对碳青霉烯类的耐药率高。上述结果显示细菌耐药性监测对于细菌感染的有效治疗十分重要。

The integrated luminosities of data samples collected in the bEsⅢ experiment in 2016-2017 at centerof-mass energies between 4.19 and 4.28 GeV are measured with a precision better than 1% by analyzing large-angle bhabha scattering *** integrated luminosities of old datasets collected in 2010-2014 are updated by considering corrections related to detector performance,offsetting the effect of newly discovered readout errors in the electromagnetic calorimeter,which can haphazardly occur.

studies of e^+e~→d_s^+■^((*)0)K^-and the P-wave charmed-strange mesons are performed based on an e^+e^-collision data sample corresponding to an integrated luminosity of 567 pb^(-1) collected with the bEsIII detector at s^(1/2)=4.600 GeV. The processes of e^+e^-→d_s^+■^(*0)K^- and d_s^+■~0K^- are observed for the first time and are found to be dominated by the modes d_s^+d_(s1)(2536)^-and d_s^+d_(s2)~*(2573)^-, respectively. The born cross sections are measured to be σ~b(e^+e^-→d_s^+■^(*0)K^-) =(10.1±2.3±0.8) pb and σ~b(e^+e^-→d_s^+■~0K^-) =(19.4±2.3± 1.6) pb, and the products of born cross section and the decay branching fraction are measured to be σ~b(e^+e^-→d_s^+d_(s1)(2536)^-+c.c.)·b(d_(s1)(2536)^-→■^(*0)K^-)=(7.5±1.8±0.7) pb and σ~b(e^+e^-→d_s^+d_(s2)~*(2573)^-+ c.c.)·b(d_(s2)~*(2573)^-→■~0 K^-)=(19.7 ± 2.9 ±2.0) pb. For the d_(s1)(2536)^-and d_(s2)~*(2573)^-mesons, the masses and widths are measured to be m(d_(s1)(2536)^-)=(2537.7±0.5 ±3.1) meV/c2, Γ(d_(s1)(2536)^-) =(1.7 ±1.2 ±0.6)meV, and m(d_(s2)~*(2573)^-)=(2570.7±2.0 ±1.7) meV/c^2, Γ(d_(s2)~*(2573)^-)=(17.2 ±3.6 ±1.1) meV. The spin-parity of the d_(s2)~*(2573)^-meson is determined to be j^p= 2^+. In addition, the processes e^+e^-→d_s^+■^((*)0)K^-are searched for using the data samples taken at four(two) center-of-mass energies between 4.416(4.527) and 4.575 GeV, and upper limits at the 90% confidence level on the cross sections are determined.

we report a search for a heavier partner of the recently observed z_(cs)(3985)^(-) state,denoted as z_(cs)^('-),in the process e^(+)e^(−)→K^(+)d_(s)^(∗−) d^(∗0 )+ c.c.,based on e^(*)e^(-)collision data collected at the center-of-mass energies of √s=4.661,4.682 and 4.699 GeV with the bEsIII *** z_(cs)^('-) is of interest as it is expected to be a candidate for a hidden-charm and open-strange tetraquark.A partial-reconstruction technique is used to isolate K^(+)recoil-mass spectra,which are probed for a potential contribution from z_(cs)^('-)→d_(s)^(∗−) d^(∗0 )+ *** find an excess of z_(cs)^('-)→d_(s)^(*-)-d^(*0)(c.c.)candidates with a significance of 2.1o,after considering systematic uncertainties,at a mass of(4123.5±0.7_(sat)±4.7_(syst.))meV/c^(2).As the data set is limited in size,the upper limits are evaluated at the 90%confidence level on the product of the born cross sections(σ^(borm))and the branching fraction(b)of z_(cs)^('-)→d_(s)^(*-)-d^(*0),under different assumptions of the z_(cs)^('-) mass from 4.120 to 4.140 meV and of the width from 10 to 50 meV at the three center-of-mass *** upper limits of σ^(born).b are found to be at the level of O(1)pb at each *** data samples are needed to confirm the z_(cs)^('-) state and clarify its nature in the coming years.

Using electron-positron annihilation data samples corresponding to an integrated luminosity of 4.5 fb-1,collected by the bEsⅢdetector in the energy region between 4599.53 meV and 4698.82 meV,we report the first observations of the Cabibbo-suppressed decaysΛ_(c)^(+)→nπ^(+)π^(0),Λ_(c)^(+)→nπ^(+)π^(-)π^(+),and the Cabibbo-favored decayΛ_(c)^(+)→nK^(-)π^(+)π^(+)with statistical significances of 7.9σ,7.8σ,and>10σ,*** branching fractions of these decays are measured to be b(Λ_(c)^(+)→nπ^(+)π^(0))=(0.64±0.09±0.02)%,b(Λ_(c)^(+)→nπ^(+)π^(-)π^(+))=(0.45±0.07±0.03)%,and b(Λ_(c)^(+)→nK^(-)π^(+)π^(+))=(1.90±0.08±0.09)%,where the first uncertainties are statistical and the second are *** find that the branching fraction of the decayΛ_(c)^(+)→nπ^(+)π^(0)is about one order of magnitude higher than that ofΛ_(c)^(+)→nπ^(+).

Optical frequency combs in microresonators(microcombs)have a wide range of applications in science and technology,due to its compact size and access to considerably larger comb *** recent successes,the problems of self-starting,high mode efficiency as well as high output power have not been fully addressed for conventional soliton *** demonstration of laser cavity soliton microcombs by nesting a microresonator into a fiber cavity,shows great potential to solve the *** we study the dissipative soliton generation and interaction dynamics in a microresonator-fltered fiber laser in both theory and *** bring theoretical insight into the mode-locking principle,discuss the parameters effect on soliton properties,and provide experimental guidelines for broadband soliton *** predict chirped bright dissipative soliton with flat-top spectral envelope in microresonators with normal dispersion,which is fundamentally forbidden for the externally driven ***,we experimentally achieve soliton microcombs with large bandwidth of~10 nm and high mode efficiency of 90.7%.Finally,by taking advantage of an ultrahigh-speed time magnifier,we study the real-time soliton formation and interaction dynamics and experimentally observe soliton Newton's *** study will benefit the design of the novel,high-efficiency and self-starting microcombs for real-world applications.
