On the Naturalness of Higgs Inflation

We critically examine the recent claim that the Standard Model Higgs boson H could drive inflation in agreement with observations if |H|2 has a strong coupling ξ ∼ 10 to the Ricci curvature scalar. We first show that the effective theory approach upon which that claim is based ceases to be valid beyond a cutoff scale Λ = mp/ξ, where mp is the reduced Planck mass. We then argue that knowing the ...

Constraints Placed on the Higgs Sector from Precision Electroweak Measurements

In this lecture, I would like to investigate what precision electroweak measurements have to tell us about the Higgs sector. I will show that the radiative corrections to electroweak interaction observables coming from the Higgs sector can be summarized into three parameters S, T, and U. The precision measurements of the observables will constrain S and 2’. By comparing these constraints with t...

Naturalness of Asymptotically Safe Higgs

We extend the list of theories featuring a rigorous interacting ultraviolet fixed point by constructing the first theory featuring a Higgs-like scalar with gauge, Yukawa and quartic interactions. We show that the theory enters a perturbative asymptotically safe regime at energies above a physical scale 3. We determine the salient properties of the theory and use it as a concrete example to test...

Improved Higgs Naturalness with Supersymmetry

We present a supersymmetric model of electroweak symmetry-breaking exhibiting improved naturalness, wherein the stop mass can be pushed beyond the reach of the Large Hadron Collider without unnatural fine tuning. This implies that supersymmetry may still solve the hierarchy problem, even if it eludes detection at the LHC. CONSTRAINTS ON THE SCALE OF NEW PHYSICS The standard model (SM) of partic...

Higgs boson mass constraints from precision data and direct searches

Two of the nine measurements of sin2θ eff , the effective weak interaction mixing angle, are found to be in significant conflict with the direct search limits for the Standard Model (SM) Higgs boson. Using a scale factor method, analogous to one used by the Particle Data Group, we assess the possible effect of these discrepancies on the SM fit of the Higgs boson mass. The scale factor fits incr...
