1  AABOUD 2017S analyze electroweak production of a ${{\mathit W}}$ boson in association with two jets at high dijet invariant mass, with the ${{\mathit W}}$ boson decaying to electron or muon plus neutrino. In the signal region of dijet mass larger than 1 TeV and leading-jet transverse momentum larger than 600 GeV, 30 events are observed in the data with $39$ $\pm4$ events expected in the Standard Model, yielding the following limits at 95$\%$ CL for the form factor cut-off scale ${{\mathit \Lambda}_{{FF}}}\rightarrow\infty{}$: $-33$ $<$ ${{\mathit c}_{{W}}}/\Lambda {}^{2}$ $<$ $30$, $-170$ $<$ ${{\mathit c}_{{B}}}/\Lambda {}^{2}$ $<$ $160$, $-13$ $<$ ${{\mathit c}_{{WWW}}}/\Lambda {}^{2}$ $<$ $9$, $-580$ $<$ ${{\mathit c}}_{{{\widetilde{\mathit W}}}}/\Lambda {}^{2}$ $<$ $580$, $-11$ $<$ ${{\mathit c}}_{{{\widetilde{\mathit W}}}WW}/\Lambda {}^{2}$ $<$ $11$, in units of TeV${}^{-2}$.
2  AABOUD 2017U analyze production of ${{\mathit W}}{{\mathit W}}$ or ${{\mathit W}}{{\mathit Z}}$ boson pairs with one ${{\mathit W}}$ boson decaying to electron or muon plus neutrino, and the other ${{\mathit W}}$ or ${{\mathit Z}}$ boson decaying hadronically. The hadronic decay system is reconstructed as either a resolved two-jet system or as a single large jet. Analysing the transverse momentum distribution of the hadronic system above 100 GeV yields the following limits at 95$\%$ CL for the form factor cut-off scale ${{\mathit \Lambda}_{{FF}}}$ $\rightarrow$ $\infty{}$: $-3.1$ $<$ ${{\mathit c}_{{WWW}}}/\Lambda {}^{2}$ $<$ $3.1$, $-19$ $<$ ${{\mathit c}_{{B}}}/\Lambda {}^{2}$ $<$ $20$, $-5.1$ $<$ ${{\mathit c}_{{W}}}/\Lambda {}^{2}$ $<$ $5.8$, in units of TeV${}^{-2}$.
3  KHACHATRYAN 2017O analyse ${{\mathit W}}{{\mathit Z}}$ production where each boson decays into electrons or muons. Events are required to have a tri-lepton invariant mass larger than 100 GeV, with one of the lepton pairs having an invariant mass within 20 GeV of the ${{\mathit Z}}$ boson mass. The ${{\mathit Z}}$ transverse momentum spectrum is analyzed to set 95$\%$ C.L. limits of: $-260$ $<$ ${{\mathit c}_{{B}}}/\Lambda {}^{2}$ $<$ $210$, $-4.2$ $<$ ${{\mathit c}_{{W}}}/\Lambda {}^{2}$ $<$ $8.0$, $-4.6$ $<$ ${{\mathit c}_{{WWW}}}/\Lambda {}^{2}$ $<$ $4.2$, in units of TeV${}^{-2}$.
4  SIRUNYAN 2017X study ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit W}}{{\mathit W}}$ / ${{\mathit W}}$ ${{\mathit Z}}$ $\rightarrow$ ${{\mathit \ell}}{{\mathit \nu}}{{\mathit q}}{{\overline{\mathit q}}}$ production at 8 TeV where ${{\mathit \ell}}$ is an electron or muon with $p_T$ $>$ 30 or 25 GeV respectively. Suitable cuts are put on the $p_T$ of the dijet system and the missing $\mathit E_{T}$ of the event yielding a total of 285 and 204 ${{\mathit W}}{{\mathit V}}$ events observed in the electron and muon channels. The following 95$\%$ C.L. limits in units of TeV${}^{-2}$ are obtained: $-2.7$ $<$ ${{\mathit c}_{{W W W}}}/\Lambda {}^{2}$ $<$ 2.7, $-14$ $<$ ${{\mathit c}_{{B}}}/\Lambda {}^{2}$ $<$ 17, $-2.0$ $<$ ${{\mathit c}_{{W}}}/\Lambda {}^{2}$ $<$ 5.7.
5  AAD 2016AR study ${{\mathit W}}{{\mathit W}}$ production in ${{\mathit p}}{{\mathit p}}$ collisions and select 6636 ${{\mathit W}}{{\mathit W}}$ candidates in decay modes with electrons or muons with an expected background of $1546$ $\pm157$ events. Assuming an EFT formulation, a fit to the transverse momentum distribution of the leading charged lepton, leads to 95$\%$ C.L. ranges of: $-4.61<{{\mathit c}_{{WWW}}}/\Lambda {}^{2}<$ 4.60, $-5.87<{{\mathit c}_{{W}}}/\Lambda {}^{2}<$ 10.54 and $-20.9<{{\mathit c}_{{B}}}/\Lambda {}^{2}<$ 26.3,in units of TeV${}^{-2}$.
6  AAD 2016P study ${{\mathit W}}{{\mathit Z}}$ production in ${{\mathit p}}{{\mathit p}}$ collisions and select 2091 ${{\mathit W}}{{\mathit Z}}$ candidates in 4 decay modes with electrons and muons, with an expected background of $1825$ $\pm7$ events. Analyzing the ${{\mathit W}}{{\mathit Z}}$ transverse momentum distribution, the resulting 95$\%$ C.L. limits are: $-3.9<{{\mathit c}_{{WWW}}}/\Lambda {}^{2}<$ 4.0, $-4.3<{{\mathit c}_{{W}}}/\Lambda {}^{2}<$ 6.8, and $-320<{{\mathit c}_{{B}}}/\Lambda {}^{2}<$ 210, in units of TeV${}^{-2}$.
7  KHACHATRYAN 2016BI determine the ${{\mathit W}^{+}}{{\mathit W}^{-}}$ production cross section using unlike sign di-lepton (${{\mathit e}}$ or ${{\mathit \mu}}$) events with high $p_T$. The leptons have $p_T$ $>$ 20 GeV/c and are isolated. Events are required to have no jets above $p_T$ of 30 GeV/c. 4847 (2233) events are selected with different (same) flavor leptons, with an expected total background of $1179$ $\pm123$ ($643$ $\pm73$) events. Analysing the di-lepton invariant mass spectrum, the following values are obtained: ${{\mathit c}_{{WWW}}}/\Lambda {}^{2}$ = $0.1$ $\pm3.2$, ${{\mathit c}_{{W}}}/\Lambda {}^{2}$ = $-3.6$ ${}^{+5.0}_{-4.5}$ and ${{\mathit c}_{{B}}}/\Lambda {}^{2}$= $-3.2$ ${}^{+15.0}_{-14.5}$, in units of TeV${}^{-2}$. The limits at 95$\%$ C.L. are: $-5.7<{{\mathit c}_{{WWW}}}/\Lambda {}^{2}<$5.9, $-11.4<{{\mathit c}_{{W}}}/\Lambda {}^{2}<$5.4 and $-29.2<{{\mathit c}_{{B}}}/\Lambda {}^{2}<$23.9, in units of TeV${}^{-2}$.
