Production of single W bosons at LEP and measurement of WWγ gauge coupling parameters

Single W boson production in electron–positron collisions is studied with the L3 detector at centre-of-mass energies between 192 GeV and 209 GeV. Events with two acoplanar hadronic jets or a single energetic lepton are selected, and the single W cross section is measured. Combining the results with...

description Single W boson production in electron–positron collisions is studied with the L3 detector at centre-of-mass energies between 192 GeV and 209 GeV. Events with two acoplanar hadronic jets or a single energetic lepton are selected, and the single W cross section is measured. Combining the results with measurements at lower centre-of-mass energies, the ratio of the measured cross section to the Standard Model expectation is found to be 1.12<sup>+0.11</sup><sub>−0.10</sub>± 0.03. From all single W data, the WWγ gauge coupling parameter κ<sub>γ</sub> is measured to be 1.116<sup>+0.082</sup><sub>−0.086</sub>± 0.068.
