Pseudo-goldstino and electroweakinos via VBF processes at LHC
The multi-sector SUSY breaking predicts pseudo-goldstino which can couple to
the visible sector more strongly than the ordinary gavitino and thus induce the
decays of the lightest neutralino and chargino (collectively called
electroweakinos) inside the detector. In this note we study the electroweakino
pair productions via vector boson fusion (VBF) processes followed by decays to
pseudo-goldstino at the LHC. Our Monte Carlo simulations show that at the 14
TeV LHC with 3000 fb^{-1} luminosity the dominant production channel
pp->chargino+neutralino+2 jets can have a statistical significance above
2-sigma while other production channels are not accessible.Comment: Version in JHEP (comments added
Two-Higgs-doublet model with a color-triplet scalar: a joint explanation for top quark forward-backward asymmetry and Higgs decay to diphoton
The excess of top quark forward-backward asymmetry () reported by
the Tevatron and the enhancement of the Higgs decay to diphoton observed by the
LHC may point to a same origin of new physics. In this note we examined such
anomalies in the two-Higgs-doublet model with a color-triplet scalar. We found
that under current experimental constraints this model can simultaneously
explain both anomalies at level. Also, we examined the Higgs decay
and displayed its correlation with . We found
that unlike other models, this model predicts a special correlation between
and , i.e., the rate is highly
suppressed while the rate is enhanced. This behavior may help to
distinguish this model in the future high luminosity run of the LHC.Comment: 18pages, 4figures, references adde
