Global Analysis of General SU(2) x SU(2) x U(1) Models with Precision Data
Ken Hsieh, Kai Schmitz, Jiang-Hao Yu +1
We present the results of a global analysis of a class of models with an extended electroweak gauge group of the form SU(2) x SU(2) x U(1), often denoted as G(221) models, which in…
Z to b bbar and Chiral Currents in Higgsless Models
Tomohiro Abe, R. Sekhar Chivukula, Neil D. Christensen +4
In this note we compute the flavor-dependent chiral-logarithmic corrections to the decay Z to b bbar in the three site Higgsless model. We compute these corrections diagrammaticall…
Lone Higgs at the LHC
Ken Hsieh, C. -P. Yuan
We address the possible scenario that the Large Hadron Collider (LHC) discovers only a Higgs boson after 10 fb^{-1} of operation, and attempt to identify this Higgs boson as that o…
Triplet Extended Supersymmetric Standard Model
Stefano Di Chiara, Ken Hsieh
We revisit an extension of the MSSM by adding a hypercharge-neutral, SU(2)-triplet chiral superfield. Similar to the NMSSM, the triplet gives an additional contribution to the quar…
Pseudo-Dirac Bino Dark Matter
Ken Hsieh
While the bino-dominated lightest neutralino of the minimal supersymmetric Standard Model (MSSM) is an interesting and widely-studied candidate of the dark matter, the p-wave suppr…
Mixed Dark Matter in Universal Extra Dimension Models with TeV Scale and
Ken Hsieh, R. N. Mohapatra, Salah Nasri
We show that in a class of universal extra dimension (UED) models that solves both the neutrino mass and proton decay problems using low scale left-right symmetry, the dark matter…
