Anomalous ${{\mathit W}}$ quartic couplings are measured by the experiments at LEP, the Tevatron, and the LHC. Some of the recent results from the Tevatron and LHC experiments individually surpass the combined LEP-2 results in precision (see below). As discussed in the review on the “Anomalous ${{\mathit W}}/{{\mathit Z}}$ quartic couplings (QGCS),” the measurements are typically done using different operator expansions which then do not allow the results to be compared and averaged. At least one common framework should be agreed upon for the use in the future publications by the experiments.

Some publications from LHC experiments derive limits for various assumed values of the form-factor cutoff $\Lambda _{FF}$. The values quoted below are for $\Lambda _{FF}$ $\rightarrow$ $\infty{}$.

The measured differential cross section as a function of the photon energy and photon polar angle is used to extract the 95$\%$ CL limits: $-0.020$ GeV${}^{-2}<\mathit a_{0}/\Lambda {}^{2}<0.020$ GeV${}^{-2}$, $-0.053$~GeV${}^{-2}<\mathit a_{c}/\Lambda {}^{2}<0.037$ GeV${}^{-2}$ and $-0.16$ GeV${}^{-2}<\mathit a_{n}/\Lambda {}^{2}<0.15$ GeV${}^{-2}$. 38  ABBIENDI 2004L select 20 ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \nu}}{{\overline{\mathit \nu}}}{{\mathit \gamma}}{{\mathit \gamma}}$ acoplanar events in the energy range $180 - 209$ GeV and 176 ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit q}}{{\overline{\mathit q}}}{{\mathit \gamma}}{{\mathit \gamma}}$ events in the energy range $130 - 209$ GeV. These samples are used to constrain possible anomalous ${{\mathit W}^{+}}{{\mathit W}^{-}}{{\mathit \gamma}}{{\mathit \gamma}}$ and ${{\mathit Z}}{{\mathit Z}}$ ${{\mathit \gamma}}$ ${{\mathit \gamma}}$ quartic couplings. Further combining with the ${{\mathit W}^{+}}{{\mathit W}^{-}}{{\mathit \gamma}}$ sample of ABBIENDI 2004B the following one--parameter 95$\%$ CL limits are obtained: $-0.007$ $<{{\mathit a}_{{{0}}}^{Z}}/\Lambda {}^{2}<$ 0.023 GeV${}^{-2}$, $-0.029$ $<{{\mathit a}_{{{c}}}^{Z}}/\Lambda {}^{2}<$ 0.029 GeV${}^{-2}$, $-0.020$ $<{{\mathit a}_{{{0}}}^{W}}/\Lambda {}^{2}<$ 0.020 GeV${}^{-2}$, $-0.052$ $<{{\mathit a}_{{{c}}}^{W}}/\Lambda {}^{2}<$ 0.037 GeV${}^{-2}$. 39  In the CM energy range 183 to 209 GeV HEISTER 2004A select 30 ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \nu}}{{\overline{\mathit \nu}}}{{\mathit \gamma}}{{\mathit \gamma}}$ events with two acoplanar, high energy and high transverse momentum photons. The photon$-$photon acoplanarity is required to be $>$ 5$^\circ{}$, $\mathit E_{{{\mathit \gamma}}}/\sqrt {s }$ $>$ 0.025 (the more energetic photon having energy $>$ 0.2 $\sqrt {s }$), p$_{T_{\gamma }}/E_{{\mathrm {beam}}}$ $>$ 0.05 and $\vert $cos $ \theta _{\gamma }\vert $ $<$ 0.94. A likelihood fit to the photon energy and recoil missing mass yields the following one--parameter 95$\%$ CL limits: $-0.012$ $<$ ${{\mathit a}_{{{0}}}^{Z}}/\Lambda {}^{2}$ $<$ 0.019 GeV${}^{-2}$, $-0.041$ $<$ ${{\mathit a}_{{{c}}}^{Z}}/\Lambda {}^{2}$ $<$ 0.044 GeV${}^{-2}$, $-0.060$ $<$ ${{\mathit a}_{{{0}}}^{W}}/\Lambda {}^{2}$ $<$ 0.055 GeV${}^{-2}$, $-0.099$ $<$ ${{\mathit a}_{{{c}}}^{W}}/\Lambda {}^{2}$ $<$ 0.093 GeV${}^{-2}$. 40  ABDALLAH 2003I select 122 ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit W}^{+}}{{\mathit W}^{-}}{{\mathit \gamma}}$ events in the C.M. energy range $189 - 209$ GeV, where $\mathit E_{{{\mathit \gamma}}}>$5 GeV, the photon has a polar angle $\vert $cos $\theta _{{{\mathit \gamma}}}\vert <0.95$ and is well isolated from the nearest charged fermion. A fit to the photon energy spectra yields $\mathit a_{\mathit c}/\Lambda {}^{2}$= $0.000$ ${}^{+0.019}_{-0.040}$ GeV${}^{-2}$, $\mathit a_{0}/\Lambda {}^{2}$= $-0.004$ ${}^{+0.018}_{-0.010}$ GeV${}^{-2}$, ${{\widetilde{\mathit a}}}_{0}/\Lambda {}^{2}$= $-0.007$ ${}^{+0.019}_{-0.008}$ GeV${}^{-2}$, $\mathit a_{\mathit n}/\Lambda {}^{2}$= $-0.09$ ${}^{+0.16}_{-0.05}$ GeV${}^{-2}$, and ${{\widetilde{\mathit a}}}_{\mathit n}/\Lambda {}^{2}$= $+0.05$ ${}^{+0.07}_{-0.15}$ GeV${}^{-2}$, keeping the other parameters fixed to their Standard Model values$~$(0). The 95$\%$ CL limits are: $-0.063$ GeV${}^{-2}<\mathit a_{\mathit c}/\Lambda {}^{2}<+0.032$ GeV${}^{-2}$, $-0.020$ GeV${}^{-2}<\mathit a_{0}/\Lambda {}^{2}<+0.020$ GeV${}^{-2}$, $-0.020$ GeV${}^{-2}<{{\widetilde{\mathit a}}}_{0}/\Lambda {}^{2}<+0.020$ GeV${}^{-2}$, $-0.18$ GeV${}^{-2}<\mathit a_{\mathit n}/\Lambda {}^{2}<+0.14$ GeV${}^{-2}$, $-0.16$ GeV${}^{-2}<{{\widetilde{\mathit a}}}_{\mathit n}/\Lambda {}^{2}<+0.17$ GeV${}^{-2}$. 41  ACHARD 2002F select 86 ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit W}^{+}}{{\mathit W}^{-}}{{\mathit \gamma}}$ events at $192 - 207$ GeV, where $\mathit E_{{{\mathit \gamma}}}>$5 GeV and the photon is well isolated. They also select 43 acoplanar ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \nu}}{{\overline{\mathit \nu}}}{{\mathit \gamma}}{{\mathit \gamma}}$ events in this energy range, where the photon energies are $>5~$GeV and $>1~$GeV and the photon polar angles are between 14$^\circ{}$ and 166$^\circ{}$. All these 43 events are in the recoil mass region corresponding to the ${{\mathit Z}}$ ($75 - 110$ GeV). Using the shape and normalization of the photon spectra in the ${{\mathit W}^{+}}{{\mathit W}^{-}}{{\mathit \gamma}}$ events, and combining with the 42 event sample from 189 GeV data (ACCIARRI 2000T), they obtain: $\mathit a_{0}/\Lambda {}^{2}$= $0.000$ $\pm0.010$ GeV${}^{-2}$, $\mathit a_{\mathit c}/\Lambda {}^{2}$= $-0.013$ $\pm0.023$ GeV${}^{-2}$, and $\mathit a_{\mathit n}/\Lambda {}^{2}$= $-0.002$ $\pm0.076$ GeV${}^{-2}$. Further combining the analyses of ${{\mathit W}^{+}}{{\mathit W}^{-}}{{\mathit \gamma}}$ events with the low recoil mass region of ${{\mathit \nu}}{{\overline{\mathit \nu}}}{{\mathit \gamma}}{{\mathit \gamma}}$ events (including samples collected at $183+189$ GeV), they obtain the following one-parameter 95$\%$ CL limits: $-0.015$ GeV${}^{-2}<\mathit a_{0}/\Lambda {}^{2}<0.015$ GeV${}^{-2}$, $-0.048$ GeV${}^{-2}<\mathit a_{\mathit c}/\Lambda {}^{2}<0.026$ GeV${}^{-2}$, and $-0.14$ GeV${}^{-2}<\mathit a_{\mathit n}/\Lambda {}^{2}<0.13$ GeV${}^{-2}$.
