| الوصف: | The CDF Collaboration reported an excess in the production of two jets in association with a W. We discuss constraints on possible new particle state interpretations of this excess. The fact of no statistically significant deviation from the SM expectation for Z+dijet events in CDF data disfavors the new particle explanation. We show that the nucleon intrinsic strange quarks provide an important contribution to the W boson production in association with a single top quark production. Such W+t single top quark production can contribute to the CDF W+dijet excess, thus the nucleon intrinsic quarks can provide a possible explanation to the CDF excess in W+dijet but not in Z+dijet events. ; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000300285100013&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Physics, Nuclear ; Physics, Particles & Fields ; SCI(E) ; 6 ; ARTICLE ; 12 ; null ; 47 |
