Unparticles and electroweak symmetry breaking

TL;DR

This paper explores how unparticle physics can induce electroweak symmetry breaking, leading to the emergence of a Higgs boson and a new scalar particle through a novel scalar potential.

Contribution

It introduces a scalar potential inspired by unparticles that demonstrates electroweak symmetry breaking and predicts new scalar particles.

Findings

Electroweak symmetry is broken at tree level with unparticle interactions.

The unparticle sector's scale invariance is broken, producing a Higgs and a lighter scalar.

A non-integral power scalar potential models unparticle effects on symmetry breaking.

Abstract

We investigate a scalar potential inspired by the unparticle sector for the electroweak symmetry breaking. The scalar potential contains the interaction between the standard model fields and unparticle sector. It is described by the non-integral power of fields that originates from the nontrivial scaling dimension of the unparticle operator. It is found that the electroweak symmetry is broken at tree level when the interaction is turned on. The scale invariance of unparticle sector is also broken simultaneously, resulting in a physical Higgs and a new lighter scalar particle.
