A phenomenological Lagrangian approach is employed to study the electromagnetic properties of the deuteron. The deuteron is regarded as a weakly bound state of the proton and neutron. We construct a general form for the electromagnetic one- and two-body transition operators formulated in terms of the nucleon fields, which are then used in the calculation of the electromagnetic deuteron form factors. One of the two-body operators is responsible for explaining the quadrupole moment form factor. We show that in our approach the data on the deuteron form factors as well as on the differential cross section of elastic electron-deuteron scattering are well explained.
The Power Of Effective Field Theories In Nuclei: The Deuteron, NN Scattering and Electroweak Processes
我们展示了如何有效有效的量子场论工作在核物理。利用物理上透明的截断正则化方法,我们研究了最简单的两核子核系统的束缚态和散射态,其动量尺度远小于π介子质量。我们考虑了氘核的所有静态性质、双核子散射相移、热能下的n + p --> d + γ过程和太阳质子聚变过程p + p --> d + e(+)+v(e),并证明了这些都在次领先阶展开中得到了很高的精度描述。我们探讨如何一个“新的”自由度进入一个有效的理论打开和关闭的作用,π介子的拉格朗日。

Application of chiral resonance Lagrangian theories to the muon g-2
我们认为,唯象共振拉格朗日模型,从低能强子反应数据的全局拟合的约束,可以帮助改善μ子g-2的预测。主要的问题是那些贡献,不能计算微扰手段:强子真空极化(HVP)的影响和强子光-由-光(HLbL)散射的贡献。我回顾了最近的进展,在评估的HVP的贡献打破隐藏的局部对称性(HLS)的框架内,与M。Benayoun,P. David and L.德尔博诺我们的HLS驱动估计读取a_mu(LO had)=(688.60+/-4.24)10^{-10},并且我们发现a_mu(理论)=(11 659 177.65 +/- 5.76)10^{-10}。

Phenomenological Aspects of Isospin Violation in the Nuclear Force
唯象拉格朗日量和量纲幂计数被用来评估核子-核子力中的同位旋破坏。研究了$πNN$耦合常数(包括Goldberger-Treiman差异)、电荷对称性破缺和介子混合模型。利用手征微扰理论对同位旋破坏的$πNN$耦合常数进行了单圈分析。介子混合模型和$^3$ He - $^3$ H质量差也讨论了自然的背景下。
