Radial Regge trajectories higher $\psi(nS)$ $\psi(nD)$ states

The masses of ((n + 1) 3S1) and (n 3D1) are calculated using the relativistic string Hamiltonian with “linear+gluon-exchange” potential. They occur in the range 4.5–5.8 GeV, in particular.
Let $\Psi(n):=n\prod_{p | n}(1+\frac{1}{p})$ denote the Dedekind $\Psi$ function. Define, for $n\ge 3,$ the ratio $R(n):=\frac{\Psi(n)}{n\log\log n}.$ We prove unconditionally that $R(n)\le e^\gamma$...
A study of charged kappa in $J/\psi \to K^{\pm} K_s \pi^{\mp} \pi^0$
$J/\psi \ K^{\pm} K_s \pi^{\mp} \pi^0$ mass spectrum

Based on $58 \times 10^6 $ $J/\psi$ events collected by BESII, the decay $J/\psi \to K^{\pm} K_s \pi^{\mp} \pi^0$ is studied. In the invariant mass spectrum recoiling against the charged $K^*(892)^{\p...

2010/3/15
The decay channel $\psi^\prime\to\pi^+\pi^-J/\psi(J/\psi\to\gamma p\bar{p})$ is studied using a sample of $1.06\times 10^8$ $\psi^\prime$ events collected by the BESIII experiment at BEPCII. A strong ...

In this paper, we introduce the notion of Quasi αψ-open function and investigate some of its fundamental properties and its characterisations.

Asymmetric pairingse: G1 ×G2 ! GT for which an efficiently-computable
isomorphism: G2 ! G1 is known are called Type 2 pairings; if such an isomorphism
is not known then e is called a Type 3 pairin...
Differential Subordination Results for New Classes of the Family $ \mathcal{E}( \Phi, \Psi)$
Fractional calculus Subordination Hadamard product

We define new classes of the family in a unit disk where the operator denotes the convolution or Hadamard product. Moreover, we establish some subordination results for these new classes.

单位球面上的等距及$\lambda,\psi, 2$-等距映射的延拓
等距映射 等距延拓 Tingley 问题
2007/12/12
本文得到了赋$\beta$-范空间($0<\beta\leq1$)的单位球面(或球)上的等距映射可以延拓为全空间上的线性等距映射的一些充分条件, 然后在赋$\beta$-范线性空间$E$中研究$(\lambda,\psi,2)$-等距映射的延拓问题, 主要结果为: 正齐性映射$V_0 : B_{1}(E) \rightarrow B_{1}(E)$ 是$(1,\psi,2)$-等距的充要条件为 ...

本文研究有穷圆内$\psi(z)f(z)f^{'}(z)$的值分布，其中f(z)为非常数亚纯函数，$\psi(z)$为非零亚纯函数，并对平面上这样的函数，若$T(r,\psi)=S(r,f)$，得到$T(r,f)<\frac{9}{2} N(r,f)+\frac{9}{2} N(r,\frac{1}{\psi f f^{'}})+S(r,f)$
