in this work,we investigate the SU(3)flavor symmetry,neavy quark spin symmetry and their breaking effects in the di-meson systems.We prove the existence of the[(D)*sD*s]0++,[(D)*sDs/(D)sD*s]1+-,and[(D)*sD*s]1+-bound states as the consequence of two prerequisites in the SU(3)flavor symmetry and heavy quark spin symmetry.The first prerequisite,the X(3872)as the weakly(D)*D/(D)D* bound state is supported by its mass and decay branching ratios.The second prerequisite,the existence of the[(D)sDs]bound state is supported by the lattice QCD calculation and the observation of xc0(3930)by the LHCb Collaboration.We hope the future experimental analyses can search for these bound states in the B → D(*)(s)(D)(*)(s)h processes(h denotes the light hadrons).The[(D)*sD*s]bound state is also expected to be reconstructed in the J/ψφ final state in the B → J/ψφK decay.

为了研究硅电极在充放电过程中的应力演化,在忽略弹性变形的情况下提出了一个考虑粘塑性的简化力学模型,分别导出了出现相分离和不出现相分离时薄膜电极内应力场的解析解,该模型的计算结果与现有的实验结果相吻合.计算结果表明,当存在相分离时,电极中的应力取决于薄膜电极的厚度和充电速率的乘积;在未出现相分离现象时,应力仅取决于充电速率.这个解析形式的力学模型对于锂离子电池电极材料的设计有着重要的指导意义.

Following the observation of three narrow N* pentaquark states with hidden charm,Pc(4312),Pc(4440)and Pc(4457)[1,2],very recently,the LHCb Collaboration reported the first evidence for their strange ∧* counterparts,PCS(4459),in the J/ψ∧ invariant mass dis
Seasonal abrupt climatic events severely impact ecosystems and human society.Knowledge of how seasonal abrupt climate events have evolved in the geological past is crucial for under-standing seasonal climate change,because the long duration of geological
Besides the observed quark-antiquark and three-quark states,the quark model predicts other states with integral charges,such as qq(qq)(tetraquarks)and qqqq(q)(pentaquarks).In 2015,the LHCb Collaboration observed J/ψp resonances consistent with pen-taquark
First evidence of a structure in the J/ψ∧ invariant mass distribution is obtained from an amplitude anal-ysis of Ξ-b → J/ψ∧K-decays.The observed structure is consistent with being due to a charmonium pen-taquark with strangeness with a significance of 3.1
Zhang et al.[1] reported the first direct detection of the natural supercritical CO2 (scCO2;critical point:31.1 ℃ and 72.9 atm) in a deep-sea hydrothermal system,In their study,they measured in situ the Raman bands of scCO2 bubbling from an approximately
When elemental iron is cooled from high temperatures,mag-netic moments carried by its d-electrons begin a continuous tran-sition to a state of parallel aligned moments below its Curie temperature Tc of about 1040 K.As established in the mid-1900s,the stat

Nitrogen is a limiting element for all living organisms,including plants grown in the wild and in agriculture.A group of plants,lar-gely legumes,have developed strategies to “grab” free atmospheric nitrogen by symbiotically housing nitrogen-fixing bacteri
