Probing dark-state electromagnetic form factors at future linear electron-positron colliders with polarized beams

Zhong Zhang, Yu Zhang, Zeren Simon Wang +1

We study the electromagnetic form factors of electrically neutral dark-sector particles in this paper. Concretely speaking, we focus on operators that can lead to interactions of f…
