Tobias Frederico, J. Adnei Marinho, Emanuele Pace, Giovanni Salme`

摘要:

在光阵面哈密顿动力学的框架下,研究了氘核的电磁性质,其中包含了一体和两体贡献的电流算符。在这项工作中,我们正在考虑新的两体的贡献,与动力学性质内产生的汤川模型和结构的启发,最近的分析目前的运营商,作用于三维价分量和履行沃德高桥身份。给出了磁矩的初步结果。

英文摘要:

The electromagnetic properties of the deuteron are investigated within a Light-Front Hamiltonian Dynamics framework, with a current operator that contains both one-body and two-body contributions. In this work, we are considering new two-body contributions, with a dynamical nature generated within a Yukawa model and a structure inspired by a recent analysis of the current operator, that acts on the three-dimensional valence component and fulfills the Ward-Takahashi identity. Preliminary results for the magnetic moment are shown.
