Spontaneous breaking of Weyl quadratic gravity to Einstein action and Higgs potentialClassical Theories of GravityEffective Field TheoriesHiggs PhysicsSpontaneous Symmetry BreakingWe consider the (gauged) Weyl gravity action, quadratic in the scalar curvature ([equation]) and in the Weyl tensor ([equation...
We analyze the most general coupling of a massive vector boson to a scalar field, and find that the scalar field necessarily comes with a quartic potential which has the precise shape of the shifted Higgs potential. In other words: the shape of the Higgs potential has not to be assumed, ...
We study the renormalization flow of the Higgs potential as a function of both field amplitude and energy scale. This overcomes limitations of conventional techniques that rely, e.g., on an identification of field amplitude and RG scale, or on local field expansions. Using a Higgs–Yukawa model...
摘要: This lecture discusses the Higgs boson sectors of the SM and the MSSM, in particular in view of the recently discovered particle at125.5GeV. It also covers their connection to electroweak precision physics and the implications for the consistency tests of the respective models. 关键词: Hig...
Previously, a class of regular and asymptotically flat gravitating scalar solitons (scalarons) has been constructed in the Einstein–Klein–Gordon (EKG) theory by adopting a phantom field with Higgs-like potential where the kinetic term has the wrong sig
The Higgs field is very unique as it provides a non-zero mean expected potential energy to the physical vacuum! This is, fundamentally, what makes the whole difference for our universe. We believe that it is possible to access the shape of the energy potential which is responsible for the ...
In this paper, we discuss the self-consistency condition for the spherical symmetric Klein-Gordon equation, and then discuss a natural possibility that gravity and weak coupling constants gG and gW may be defined after gEM. In this point of view, gravity and the weak force are subsidiary derive...
We can associate this wave equation with a potential (70)V(m)=12m4(x)−m2(x)M2, with its first derivative vanishing at m=M, and its second derivative being the positive V″(M)=4M2 at m=M. With fluctuations around m=M taking the form m=M+χ, for such fluctuations the potenti...
b, The excitation spectra of the model in equation (1) calculated with the parameters E 25 meV, J 5.8 meV, α = 0.15, 4.0 meV and A 2.3 meV. The spectra were convolved with the instrumental resolution (4.2 meV full-width at half-maximum). Transverse and longitudinal modes are labelled...
We develop the formalism for computing gravitational corrections to vacuum decay from de Sitter space as a sub-Planckian perturbative expansion. Non-minimal coupling to gravity can be encoded in an effective potential. The Coleman bounce continuously deforms into the Hawking-Moss bounce, until they ...
