| Abstract: | 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. |
