Measurement of exclusive γγ →W<sup>+</sup>W<sup>-</sup> production and search for exclusive Higgs boson production in pp collisions at √s = 8 TeV using the ATLAS detector

Searches for exclusively produced W boson pairs in the process pp(γγ)→pW<sup>+</sup>W<sup>-</sup>p and an exclusively produced Higgs boson in the process pp(gg)→pHp have been performed using e<sup>±</sup>μ<sup>∓</sup> final states. These measurements u...

description Searches for exclusively produced W boson pairs in the process pp(γγ)→pW<sup>+</sup>W<sup>-</sup>p and an exclusively produced Higgs boson in the process pp(gg)→pHp have been performed using e<sup>±</sup>μ<sup>∓</sup> final states. These measurements use 20.2 fb<sup>-1</sup> of pp collisions collected by the ATLAS experiment at a center-of-mass energy √s = 8 TeV at the LHC. Exclusive production of W<sup>+</sup>W<sup>-</sup> consistent with the Standard Model prediction is found with 3.0σ significance. The exclusive W+W- production cross section is determined to be σ(γγ→W<sup>+</sup>W<sup>-</sup>→e<sup>±</sup>μ<sup>∓</sup>X) = 6.9 ± 2.2(stat) ± 1.4(sys) fb, in agreement with the Standard Model prediction. Limits on anomalous quartic gauge couplings are set at 95% confidence level as -1.7×10<sup>-6</sup><a<sup>W</sup><sub>0</sub>/Λ<sup>2</sup><1.7×10<sup>-6</sup> GeV<sup>-2</sup> and -6.4×10<sup>-6</sup><a<sup>W</sup><sub>C</sub>/Λ<sup>2</sup><6.3×10<sup>-6</sup> GeV<sup>-2</sup>. A 95% confidence-level upper limit on the total production cross section for an exclusive Higgs boson is set to 1.2 pb.
