PHOTON-PHOTON SCATTERING, PION POLARIZABILITY, AND CHIRAL-SYMMETRY
Meson polarizability dispersion relations chiral perturbation theory expert at low amplitude decentralized processing
2014/12/23
Recent attempts to detect the pion polarizability via analysis of γγ→ππ measurements are examined. The connection between calculations based on dispersion relations and on chiral perturbation theory i...
Asymptotic limits and the structure of the pion form factor
Dispersion technology solve meson chiral perturbation theory high energy low energy limit
2014/12/22
We use dispersive techniques to address the behavior of the pion form factor as Q2 → ∞ and Q2 → 0. We perform the matching with the constraints of perturbative QCD and chiral perturbation theory in th...
近代物理所理论物理室的科研人员，研究pion介子阈下产生的介质效应获得一些新结论。
重离子核反应粒子产生的介质效应大小不能由实验直接确定，只能通过微观理论计算得出或者输运计算与实验数据比较间接得出，然而这样得出的结论依赖于研究的模型。近代物理所的研究表明，低能核反应pion介子产生的荷电pion介子比值的介质效应非常明显（见图1），而目前介质效应的大小还不确定，这给人们通过研究低能核反应pio...
Weak Pion and Photon Production off Nucleons in a Chiral Effective Field Theory
Weak Pion Photon Production off Nucleons Chiral Effective Field Theory
2011/1/7
Neutrino-induced pion and photon production from nucleons and nuclei are important for the
interpretation of neutrino-oscillation experiments, and these processes are potential backgrounds in the Min...
Chiral Dynamics and Dubna-Mainz-Taipei Dynamical Model for Pion-Photoproduction Reaction
Chiral symmetry threshold 0 production baryon deformation
2011/1/7
We demonstrate that the Dubna-Mainz-Taipei (DMT) meson-exchange dynamical model, which starts from an effective chiral Lagrangian, for pion photoproduction pro-vides an excellent and economic framewor...
