We conduct a study on measuring production and on the sensitivity limits at 95% confidence level on thirteen anomalous couplings obtained by dimension-8 operators related to the anomalous quartic
couplings. We consider the main
reaction with the sub-process
at the Large Hadron electron Collider (LHeC) and the Future Circular Collider-hadron electron (FCC-he). For the LHeC, energies of the
beams are taken to be
and 140 GeV and the energy of the p beams is taken to be
TeV. For the FCC-he, energies of the
beams are taken to be
and 140 GeV and the energy of the p beams is taken to be
TeV, respectively. It is interesting to note that the LHeC and the FCC-he will lead to model-independent limits on the anomalous quartic
couplings which are one order of magnitude more stringent than the CMS Collaboration limits and are competitive with other limits reported in the literature.
