LHC and Tevatron constraints on a W' model interpretation of the top quark forward-backward asymmetry
Edmond L. Berger, Zack Sullivan, Hao Zhang
Aspects of a flavor-changing W' model with right-handed couplings are addressed in this paper in light of Tevatron and LHC data. Our fit to the Tevatron top-quark forward-backward…
Dark matter with -channel mediator: a simple step beyond contact interaction
Haipeng An, Lian-Tao Wang, Hao Zhang
Effective contact operators provide the simplest parameterization of dark matter searches at colliders. However, light mediator can significantly change the sensitivity and search…
Measuring Top-Quark Polarization in Top-Pair + Missing Energy Events
Edmond L. Berger, Qing-Hong Cao, Jiang-Hao Yu +1
The polarization of a top-quark can be sensitive to new physics beyond the standard model. We propose a novel method to measure top-quark polarization, based on the charged lepton…
