(ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image).A search for exclusive or quasi-exclusive W super(+)W super(-) production by photon-photon interactions, pp arrow right p super((*))W super(+)W super(-)p super((*)), at ... TeV is reported using data collected by the CMS detector with an integrated luminosity of 5.05 fb super(-1). Events are selected by requiring a mu super( plus or minus )e super() vertex with no additional associated charged tracks and dilepton transverse momentum p sub(T)( mu super( plus or minus )e super()) > 30 GeV. Two events passing all selection requirements are observed in the data, compared to a standard model expectation of 2.2 plus or minus 0.4 signal events with 0.84 plus or minus 0.15 background. The tail of the dilepton p sub(T) distribution is studied for deviations from the standard model. No events are observed with p sub(T) >100 GeV. Model-independent upper limits are computed and compared to predictions involving anomalous quartic gauge couplings. The limits on the parameters ... with a dipole form factor and an energy cutoff Lambda sub(cutoff)=500 GeV are of the order of 10 super(-4). Figure not available: see fulltext.
