Probing anomalous quartic couplings in eγ and γγ colliders

We analyze the potential of the $e^{+}{e}^{-}$ linear colliders, operating in the eγ and γγ modes, to probe anomalous quartic vector-boson interactions through the multiple production of $W’\mathrm{s}$ and $Z’\mathrm{s}.$ We examine all ${\mathrm{SU}\left(2\right)\mathrm{}}_L\otimes {U\left(1\right)\mathrm{}}_Y$ chiral operators of order $p^4$ that lead to new four-gauge-boson interactions but do not alter trilinear vertices. We show that the eγ and γγ modes are able not only to establish the existence of a strongly interacting symmetry breaking sector but also to probe for anomalous quartic couplings of the order of ${10}^{-2}$ at 90% C.L. Moreover, the information gathered in the $e\gamma$ mode can be used to reduce the ambiguities of the $e^{+}{e}^{-}$ mode.
