Times Cited Count:0 Percentile:0.02(Instruments & Instrumentation)Lake Pumoyum Co is located on the south Tibetan Plateau. The lake terraces are developed on the eastern lake shore, and it supposed that the large lake level changes would have happened in Pumoyum Co. The in-situ terrestrial cosmogenic adionuclides can be used to estimate the earth surface processes, such as the erosion rate and exposure age dating of rocks. Here we report the results of Be values of the rock samples from the lake terraces around Pumoyum Co. The concentrations of Be were measured by the JAEA-AMS-TONO-5MV in the Tono Geoscience Center, Japan Atomic Energy Agency. The Be concentrations ranged from 3.78 to 10.810 (atoms/g), but the Be values showed the decreasing trend following to the distance from the lake shore. This result indicates that Be values of the rocks at the shore of Pumoyum Co could be influenced from the erosion rate or tectonic process rather than the exposure date resulting from the lake level changes.

Times Cited Count:2 Percentile:70.45(Physics, Particles & Fields)Combining the quark model, the quark-pair-creation mechanism and interaction, we have investigated the near-threshold -wave states in the framework of the Hamiltonian effective field theory. With the heavy quark flavor symmetry, all the parameters are determined in the sector by fitting the lattice data. The masses of the bottom-strange partners of the and are predicted, which are well consistent with the lattice QCD simulation. The two -wave states are the mixtures of the bare core and component. Moreover, we find a crossing point between the energy levels with and without the interaction Hamiltonian in the finite volume spectrum in the case, which corresponds to a CDD (Castillejo-Dalitz-Dyson) zero in the -matrix of the scattering. This CDD zero will help deepen the insights of the near-threshold states and can be examined by future lattice calculation.

The quark model, the quark-pair-creation mechanism and interaction are incorporated into the Hamiltonian effective field theory. The bare states are almost purely given by the states with heavy-quark spin bases. The physical and are the mixtures of bare core and component, while the and are almost dominated by bare . Furthermore, our model well reproduce the clear level crossing of the with the scattering state at a finite volume.

Times Cited Count:21 Percentile:84.82(Astronomy & Astrophysics)The isospin violating decays of are revisited in a coupled-channel effective field theory. In a cutoff-independent formalism, we relate the coupling constants of with the two channels to the molecular wave function. The isospin violating decays of are obtained by two equivalent approaches, which amend some deficiencies about this issue in literature. In the quantum field theory approach, the isospin violating decays arise from the coupling constants of to two di-meson channels. In the quantum mechanics approach, the isospin violating is attributed to wave functions at the origin. We bridge the isospin violating decays of to its inner structure. Our results show that the proportion of the neutral channel in is over 80%. As a by-product, we find that the strong decay width and radiative decay width are about 30 keV and 10 keV, respectively, for the binding energy from -300 keV to -50 keV.

We include the possible violations of heavy quark spin symmetry and SU(3) flavor symmetry in a comprehensive approach. Our results show that the decay rates can be used to judge whether these resonances can be different states or not.

Our results show that the decay width of is the largest one, which is just the experimental observation channel. Our theoretical total strong and radiative widths are in favor of the as a dominated bound state. Our calculation is cutoff-independent and without prior isospin assignment. The absolute partial widths and ratios of the different decay channels can be used to test the structure of state when the updated experimental results are available.

However, these soft materials meanwhile feature a general characteristic that even a very mild pressure will lead to detrimental lattice distortion and weaken the critical light-matter interaction, thereby triggering the performance degradation. Here, using the methylammonium lead iodide as a representative exploratory platform, we observed the pressure-driven lattice disorder can be significantly suppressed via hydrogen isotope effect, which is crucial for better optical and mechanical properties previously unattainable.

The model consists of the Coulomb, the linear confinement, and the hyperfine interactions. We calculate their decay amplitudes into the channels using the quark interchange method. The mass and decay width of the state are MeV and MeV, respectively, which indicates that it might be a good candidate for the recently observed state. We also obtain an isospin partner state with MeV and MeV, respectively. Future experimental search for will be very helpful.
