手征有效场论中氘核的磁形状因子

The magnetic form factor of the deuteron in chiral effective field theory

S. Kolling, E. Epelbaum, D. R. Phillips

摘要:

在电磁流算符的手征EFT展开中,我们计算了氘核的磁形状因子,直到O(eP^4)。进入等幅神经网络三电流算子二体部分的两个LEC与实验数据拟合,得到的值具有自然大小。G_M的O(eP^4)描述与动量转移Q^2 < 0.35 GeV^2的数据一致。

英文摘要:

We calculate the magnetic form factor of the deuteron up to O(eP^4) in the chiral EFT expansion of the electromagnetic current operator. The two LECs which enter the two-body part of the isoscalar NN three-current operator are fit to experimental data, and the resulting values are of natural size. The O(eP^4) description of G_M agrees with data for momentum transfers Q^2 < 0.35 GeV^2.
