Request Description and Potential
Reason for request:
The Higgsophilic Z' of Fan et al. (http://arxiv.org/pdf/1106.1682v2.pdf) was constructed to explain the anomalous dijet resonance seen in W+jet production by the CDF collaboration. Unlike most other models constructed to explain the anomaly, this model uses an s-channel resonance production, which results in fairly different kinematical characteristics for the events. D0's analysis did not observe any excess, but the model they considered used a resonance produced through the t-channel. It will be interesting to know how sensitive this same D0 search was to the other possibility of an s-channel resonance with its distinct kinematics.
Additional Information:
The basic production mode is qqbar -> Z' -> W+h- (W-h+) with the charged Higgs (h+/-) decaying into quarks. The mass of the Z' is 270 GeV and that of the charged Higgs is 150 GeV. LHE files are available for Tevatron runs.
