Electroweak Constraints on the Fourth Generation at Two Loop Order
Michael S. Chanowitz
If the Higgs-like particle at 126 GeV is the standard model Higgs boson, then SM4, the simplest four generation extension of the SM, is inconsistent with the most recent LHC data.…
A heavy little Higgs and a light Z' under the radar
Michael S. Chanowitz
The original littlest Higgs model with universal fermion couplings is found to be consistent with precision electroweak data but is strongly constrained by Tevatron limits on the p…
Higgs Mass Constraints on a Fourth Family: Upper and Lower Limits on CKM Mixing
Michael S. Chanowitz
Limits on the Higgs boson mass restrict CKM mixing of a possible fourth family beyond the constraints previously obtained from precision electroweak data alone. Existing experiment…
Bounding CKM Mixing with a Fourth Family
Michael S. Chanowitz
CKM mixing between third family quarks and a possible fourth family is constrained by global fits to the precision electroweak data. The dominant constraint is from nondecoupling o…
Z' Bosons, the NuTeV Anomaly, and the Higgs Boson Mass
Michael Chanowitz
Fits to the precision electroweak data that include the NuTeV measurement are considered in family universal, anomaly free U(1) extensions of the Standard Model. In data sets from…
A Z' Boson and the Higgs Boson Mass
Michael S. Chanowitz
The Standard Model fit prefers values of the Higgs boson mass that are below the 114 GeV direct lower limit from LEP II. The discrepancy is acute if the 3.2 sigma disagreement for…
