π介子光生数据的统一Chew-Mandeltek SAID分析

拟合piN弹性散射数据时T矩阵极点和本征相位的参数化依赖性

Parameterization dependence of T matrix poles and eigenphases from a fit to piN elastic scattering data

我们比较适合piN弹性散射数据，基于Chew-Mandelkirk矩阵形式主义。共振，其特征在于T-矩阵极点，比较适合产生和没有明确的Chew-Mandelhattan K-矩阵极点。S矩阵的对角化产生本征相位表示。虽然本征相位可以为不同的参数化显着变化，大多数T矩阵极点的位置是相对稳定的。

Extended SAID Partial-Wave Analysis of Pion Photoproduction

本文扩展了单π介子光生及相关强子生数据的统一Chew-Mandelstam描述，纳入近十年测量结果，并重点分析了极点光衰变振幅、ng耦合及权重对拟合的影响。

对偶模型中的J/Psi光生

J/Psi Photoproduction in a Dual Model

在解析S-矩阵理论的框架下研究了J/Psi光生过程。本文用Mandelivery双振幅方法计算了J/Psi光生的微分和积分弹性截面。有人认为，在低能量下，背景，这是高能衍射的低能等价物取代了坡密子交换。高能量Pomeron优势的发病估计从拟合的数据。

Exclusive photoproduction of $π^0$ up to large values of Mandelstam variables $s, t$ and $u$ with CLAS

Exclusive photoproduction cross sections have been measured for the process $γp \rightarrow pπ^0(e^+e^-(γ))$ with the Dalitz decay final state using tagged photon energies in the range of $E_γ = 1.275-5.425$ GeV. The complete angular distribution of the final state $π^0$, for the entire photon energy range up to large values of $t$ and $u$, has been measured for the first time. The data obtained show that the cross section $dσ/dt$, at mid to large angles, decreases with energy as $s^{-6.89\pm 0.26} $. This is in agreement with the perturbative QCD quark counting rule prediction of $s^{-7} $. P…
