| الوصف: | TeV scale new physics, e.g., large extra dimensions or models with anomalous triple vector boson couplings, can lead to excesses in various kinematic regions on the semileptonic productions of pp -> WW -> l nu jj at the CERN LHC, which, although suffer from large QCD background compared with the pure leptonic channel pp -> WW -> l nu l nu, can benefit from larger production rates and the reconstructable four-body mass M-l nu jj. We study the search sensitivity through the l nu jj channel at the 7 TeV LHC on relevant new physics via probing the hard tails on the reconstructed M-l nu jj and the transverse momentum of leptonically decayed W boson (P-TW), taking into account main backgrounds and including the parton shower and detector simulation effects. Our results show that with integrated luminosity of 5 fb(-1), the LHC can already discover or exclude a large parameter region of the new physics, e.g., a 95% C.L. can be set on the large extra dimensions with a cutoff scale up to 1.5 TeV, and the WWZ anomalous coupling down to, e.g. vertical bar gimel(Z)vertical bar similar to 0.1. Results are also given for the 8 TeV LHC. ; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000309584600009&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Test ; Astronomy & Astrophysics ; Physics, Particles & Fields ; SCI(E) ; 2 ; ARTICLE ; 7 ; null ; 86 |
