Study of J/psi->eta phi pi+pi- at BESIII

M. Ablikim, M. N. Achasov, X. C. Ai +402

Based on a sample of $2.25 \times 1 0^{8} J / ψ$ events taken with the BESIII detector at the BEPCII collider, we present the results of a study of the decay $J / ψ \to η ϕ π^{+} π^{-}$ . The…

I=1/2 low-lying mesons in lattice QCD

Ziwen Fu

Using conventional constituent-quark model, $I = 1/2$ scalar $κ$ , vector $K^{*} (892)$ , and axial vector $K_{1}$ mesons are studied in the asqtad-improved staggered fermion with the wa…

Precision measurement of the $D^{* 0}$ decay branching fractions

M. Ablikim, M. N. Achasov, X. C. Ai +405

Using 482 pb $^{- 1}$ of data taken at $s = 4.009$ GeV, we measure the branching fractions of the decays of $D^{* 0}$ into $D^{0} π^{0}$ and $D^{0} γ$ to be $\BR(D^{*0} \to D^0π^0)=(65.5…

Variational principle for weighted topological pressure

De-Jun Feng, Wen Huang

Let $π : X \to Y$ be a factor map, where $(X, T)$ and $(Y, S)$ are topological dynamical systems. Let $a = (a_{1}, a_{2}) \in R^{2}$ with $a_{1} > 0$ and $a_{2} \geq 0$ , and $f \in C (X)$ . Th…

Design of a 10 MeV normal conducting CW proton linac based on equidistant multi-gap CH cavities

Zhihui Li

The continue wave (CW) high current proton linac has wide applications as the front end of the high power proton machines. The low energy part is the most difficult one and there i…

Evidence for $e^{+} e^{-} \to γ χ_{c 1, 2}$ at center-of-mass energies from 4.009 to 4.360 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +405

Using data samples collected at center-of-mass energies of $s$ = 4.009, 4.230, 4.260, and 4.360 GeV with the BESIII detector operating at the BEPCII collider, we perform a s…
