چکیده
Department of Mathematics, Massachusetts Institute of Technology, Cambridge, MA 02139 Abstract We study classical dynamics in the spherical ansatz for the SU(2) gauge and Higgs fields of the electroweak Standard Model in the absence of fermions and the photon. With the Higgs boson mass equal to twice the gauge boson mass, we numerically demonstrate the existence of oscillons, extremely long-lived localized configurations that undergo regular oscillations in time. We have only seen oscillons in this reduced theory when the masses are in a two-to-one ratio. If a similar phenomenon were to persist in the full theory, it would suggest a preferred value for the Higgs mass.

An electroweak oscillon.
A numerical simulation of the full bosonic sector of the SU(2)xU(1) electroweak standard model in 3+1 dimensions demonstrates the existence of an oscillon--an extremely long-lived, localized, oscillatory solution to the equations of motion--when the Higgs mass is equal to twice the W+/- boson mass. The oscillon contains total energy 6 TeV [corrected] localized in a region of radius 0.05 fm.
متن کاملDeriving nondecoupling effects of heavy fields from the path integral: A heavy Higgs field in an SU(2) gauge theory.
We describe a method to remove non-decoupling heavy fields from a quantized field theory and to construct a low-energy one-loop effective Lagrangian by integrating out the heavy degrees of freedom in the path integral. We apply this method to the Higgs boson in a spontaneously broken SU(2) gauge theory (gauged linear σmodel). In this context, the background-field method is generalized to the no...
متن کاملU ( N ) Gauged N = 2 Supergravity and Partial Breaking of Local N = 2 Supersymmetry
We study a minimal model of U (N) gauged N = 2 supergravity with one hy-permultiplet parametrizing SO(4, 1)/SO(4) quaternionic manifold. Local N = 2 su-persymmetry is known to be spontaneously broken to N = 1 in the Higgs phase of U (1) graviphoton × U (1). Several properties are obtained of this model in the vacuum of unbroken SU (N) gauge group. In particular, we derive mass spectrum analogou...
متن کاملHamiltonian Embedding of SU(2) Higgs Model in the Unitary Gauge
Following systematically the generalized Hamiltonian approach of Batalin, Fradkin and Tyutin (BFT), we embed the second-class non-abelian SU(2) Higgs model in the unitary gauge into a gauge invariant theory. The strongly involutive Hamiltonian and constraints are obtained as an infinite power series in the auxiliary fields. Furthermore, comparing these results with those obtained from the gauge...

We point out that if there is a gauged B − 3Lτ symmetry at low energy, it can prevent fast proton decay. This may help building models with theories with extra dimensions at the TeV scale. For purpose of illustration we present an explicit model with large extra dimensions. The Higgs required for a realistic fermion masses and mixing are included. The problem of neutrino masses are solved with ...
