Charge form factors of light nuclei in chiral effective field theory

We use potentials and charge operators derived in chiral effective field theory ($\chi$EFT) to calculate charge form factors of $A=2-4$ nuclei up to next-to-next-to-next-to-next-to leading order (N4LO). The sensitivity of the results is studied as function of the cutoff $\Lambda$ in the chiral potentials and charge operators. We also present results obtained in a hybrid approach using the conventional AV18 potential and the $\chi$EFT charge operators. The theoretical results are compared to the experimental data for momentum transfers $Q$ up to $(2-3)\,m_{\pi}$. Reasonable agreement is obtained between theory and experiment.
