The mass spectrum and strong decays of the S-wave $$bar c bar s qq$$ states are studied in the compact tetraquark scenario with the quark model. The model consists of the Coulomb, the linear confinement, and the hyperfine interactions. We calculate their decay amplitudes into the $$D^{-(*)}K^{(*)}$$ channels using the quark interchange method. The mass and decay width of the $$I(J^P)=1(0^+)$$ state are $$M = 2941$$ MeV and $$Gamma_X=26.6$$ MeV, respectively, which indicates that it might be a good candidate for the recently observed $$X^0(2900)$$ state. We also obtain an isospin partner state $$I(J^P)= 0(0^+)$$ with $$M =2649$$ MeV and $$Gamma_{Xto D^- K}= 48.1$$ MeV, respectively. Future experimental search for $$X(2649)$$ will be very helpful.

Local gas-liquid two-phase flow characteristics in rod bundle geometry

Xiao, Y.*; Shen, X.*; Miwa, Shuichiro*; Sun, Haomin; Hibiki, Takashi*

Konsoryu Shimpojiumu 2018 Koen Rombunshu (Internet), 2 Pages, 2018/08

In order to develop constitutive equations of two-fluid model in rod bundle flow channels, experiments of adiabatic air-water upward two-phase flow in 6$$times$$6 rod bundle flow channel were performed. Local flow parameters such as void fraction, interfacial area concentration (IAC) and so on were measured by a double-sensor optical probe. The area-averaged void fraction and IAC data were compared with the predictions from a drift-flux model and an IAC correlation.

We report on model studies of stimulated L$$rightarrow$$H transitions. These studies use a reduced mesoscale model. Model studies reveal that L$$rightarrow$$H transition can be triggered by particle injection into a subcritical state. Particle injection changes edge mean flow shear via changes of density and temperature gradients. The change of edge mean flow shear is critical to turbulence collapse and the subsequent stimulated transition. For low ambient heating, strong injection is predicted to trigger a transient turbulence collapse. Repetitive injection at a period less than the lifetime of the collapsed state can thus maintain the turbulence collapse. The total number of injected particles required is much smaller than that required for a transition by gas puffing. We thus show that internal injection is more efficient than gas puffing of comparable strength. We also observe that zonal flows do not play a critical role in stimulated transitions.

Physics of stimulated and spontaneous L-H transitions

no journal, , 

A central issue in H-mode physics is to achieve control, not only understanding. Work in control has focused mainly on fueling by pellet injection at the near edge. We here introduce a developed one-dimensional mesoscale model, to report on the L-H transition stimulated by pellet injection. For highly heated plasmas, transition occurs spontaneously; when heat flux increases, a strong zonal flow is sufficiently excited, leading to I-phase oscillations or a single burst. When the zonal flow is excited, turbulence is reduced, allowing an ion pressure gradient to steepen. Then, mean flow shear increases to lock in the H-mode. On the other hand, studies reveal that L-H transition can be triggered by particle injection into a subcritical state. We also observe that zonal flows do not play a critical role in stimulated transitions.
