Electromagnetic form factors of ${\Lambda }_c$ in the Bethe-Salpeter equation approach

Liang-Liang Liu, Chao Wang, Xin-Heng Guo

We study the electromagnetic form factors (EMFFs) of ${\Lambda }_c$ and the quark and diquark current contributes to the EMFFs of ${\Lambda }_c$ in the space-like (SL) region in the Bethe-Salpeter e…
