In this work, we predict the light hadronic decay channels $Y(4230)\to\Lambda\bar{\Lambda}$ and $\Xi^-\bar{\Xi}^+$ when treating $Y(4230)$ as a vector charmonium state. By loop mechanism, branching ratios of processes are calculated. addition, discuss possibility carrying out search for signal through $\Lambda\bar{\Lambda}$ from $e^+e^-$ annihilation. Assuming exist in channel, also present tim...

This paper addresses the synthesis of a novel reactionless spatial 6-DOF parallel mechanism using four-bar linkages without any counter-rotations. The mechanism is first described and its kinematics is discussed. A numerical example of the reactionless 6-DOF mechanism is given in this paper and, with the help of the dynamic simulation software ADAMS, it is shown that the mechanism is reactionle...

We review the two and three-body baryonic $B$ decays with dibaryon (${\bf B\bar B'}$) as final states. Accordingly, we summarize experimental data of branching fractions, angular asymmetries, $CP$ asymmetries. Using $W$-boson annihilation (exchange) mechanism, fractions $B\to {\bf B \bf \bar B'}$ are shown to be interpretable. In approach perturbative QCD counting rules, study decay channels. p...

For control applications, the angular velocity of drive crank a four-bar mechanism is traditionally assumed to be constant. In this paper, we propose variable obtain desired output motions for coupler point. To estimate reference trajectory velocity, neural network trained with data from kinematic model. The law designed feedback linearization tracking error dynamics and Proportional–Integral–D...

Cluster formation and gas dynamics in the central regions of barred galaxies are not well understood. This paper reviews the environment of three 10 M⊙ clusters near the inner Lindblad resonance of the barred spiral NGC 1365. The morphology, mass, and flow of HI and CO gas in the spiral and barred regions are examined for evidence of the location and mechanism of cluster formation. The accretio...
