We present a simple, perturbative, and renormalizable model with a flavor symmetry which can explain both the $t\overline{t}$ forward-backward asymmetry and the bump feature present in the dijet mass distribution of the $W+jj$ sample in the range 120--160 GeV that was recently reported by the CDF collaboration. The flavor symmetry not only ensures the flavor/$CP$ safety of the model, but also relates the two anomalies unambiguously. It predicts a comparable forward-backward asymmetry in $c…

The forward-backward top asymmetry in a singlet extension of the MSSM
A bstractThe CDF and DØ collaborations have recently reported a large forward- backward asymmetry in the $ t\overline t $ system which deviates from the next to-leading order QCD standard model
Simple models for the top asymmetry: constraints and predictions
We perform a comprehensive study of the allowed range for the Tevatron $ t\bar{t} $ forward-backward asymmetries in six representative new physics models: a flavour-changing Z′ boson, a scalar
Scalar-mediated $ t\bar{t} $ forward-backward asymmetry
A large forward-backward asymmetry in $ t\bar{t} $ production, for largeinvariant mass of the $ t\bar{t} $ system, has been recently observed by the CDF collaboration. Among the scalar mediated
Dimuon CP asymmetry in B decays and collider signals in two Higgs doublet models
A bstractWe analyze the puzzle of the dimuon CP asymmetry in B decays in two Higgs doublet models. We show that the flavor changing neutral current induced by the Higgs coupling in a general two
Top quark forward-backward asymmetry in R-parity violating supersymmetry
A bstractThe interaction of bottom squark-mediated top quark pair production, occuring in the R-parity violating minimal supersymmetric standard model (MSSM), is proposed as an explanation of the
Top AFB at the Tevatron vs. charge asymmetry at the LHC in chiral U(1) flavor models with flavored Higgs doublets
We consider the top forward–backward (FB) asymmetry at the Tevatron and top charge asymmetry at the LHC within chiral U(1)′ models with flavor-dependent U(1)′ charges and flavored Higgs fields, which
A Possible Common Origin of the Top Forward-backward Asymmetry and the CDF Dijet Resonance
A color-singlet neutral vector boson is considered as a possible common origin of the top forward-backward asymmetry and the CDF dijet resonance. We identify chiral and flavor structures of the
Phenomenology of a light gluon resonance in top-physics at Tevatron and LHC
We present a phenomenological analysis of the recent Tevatron results on the $ t\overline t $ forward-backward asymmetry and invariant-mass spectrum assuming a new contribution from an s-channel
Colored bosons on top FBA and angular cross section for tt production
With full data set that corresponds to an integrated luminosity of 9.4 fb$^{-1}$, CDF has updated the top quark forward-backward asymmetry (FBA) as functions of rapidity difference $|\Delta y|$ and
What the top asymmetries tell us about single top production and Higgs decays
A bstractThe top asymmetries measured at the Tevatron, and the discrepancy in the diphoton Higgs rate under investigation at the LHC represent two possible hints of physics beyond the Standard Model
