Abstract
Searches for exclusively produced W boson pairs in the process ppðγγÞ → pWþW−p and an exclusively produced Higgs boson in the process ppðggÞ → pHp have been performed using eμ∓ final states. These measurements use 20.2 fb−1 of pp collisions collected by the ATLAS experiment at a center-of-mass energy ffiffi s p ¼ 8 TeV at the LHC. Exclusive production of WþW− consistent with the Standard Model prediction is found with 3.0σ significance. The exclusive WþW− production cross section is determined to be σðγγ → WþW− → eμ∓XÞ ¼ 6.9 2.2ðstatÞ 1.4ðsysÞ fb, in agreement with the Standard Model prediction. Limits on anomalous quartic gauge couplings are set at 95% confidence level as −1.7 × 10−6 < aW 0 =Λ2 < 1.7 × 10−6 GeV−2 and −6.4 × 10−6 < aW C =Λ2 < 6.3 × 10−6 GeV−2. A 95% confidence-level upper limit on the total production cross section for an exclusive Higgs boson is set to 1.2 pb. DO
