Summary
We introduce a novel mechanism for electroweak scale generation using Quantum Chromodynamics (QCD) and colored scalar fields. This dynamic approach, involving Higgs portal symmetry breaking, suggests new particle production at the Large Hadron Collider (LHC).
Area of Science:
- High Energy Physics
- Particle Physics
- Theoretical Physics
Background:
- The Standard Model requires an explanation for electroweak symmetry breaking.
- The hierarchy problem remains a significant challenge in particle physics.
- Quantum Chromodynamics (QCD) provides a framework for strong interactions.
Purpose of the Study:
- To propose a new, nonperturbative mechanism for generating the electroweak scale.
- To explore the role of extended scalar degrees of freedom within QCD.
- To investigate dynamical electroweak symmetry breaking via a Higgs portal.
Main Methods:
- Extending QCD with conformally invariant scalar fields.
- Utilizing dynamical symmetry breaking through scalar field condensation.
- Applying renormalization group evolution to constrain particle masses.
Main Results:
- A mechanism for generating the electroweak scale dynamically is proposed.
- A colored scalar boson with mass 350 GeV≲mS≲3 TeV is predicted.
- The colored boson is potentially discoverable at the Large Hadron Collider (LHC).
Conclusions:
- This nonperturbative approach offers a new perspective on electroweak scale generation.
- The predicted colored boson could be produced at the LHC, providing experimental tests.
- The model offers potential solutions to the hierarchy problem.

Once the fields have been calculated using Maxwell's four equations, the Lorentz force equation gives the force that the fields exert on a charged particle moving with a certain velocity. The Lorentz force equation combines the force of the electric field and of the magnetic field on the moving charge. Maxwell's equations and the Lorentz force law together encompass all the laws of electricity and magnetism. The symmetry that Maxwell introduced into his mathematical framework may not be...

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

Atoms generally contain the same number of positively and negatively charged particles, protons, and electrons. Hence, they are electrically neutral. However, the centers of the positive and negative charges do not always coincide. In such a scenario, the electric field of an atom may not be zero.
A separation of the positive and negative charges can lead to a weak, remnant effect of the positive and negative charges. The expectation is that the more the distance between the positive and...

The vacuum level denotes the energy threshold required for an electron to escape from a material surface. It is usually positioned above the conduction band of a semiconductor and acts as a benchmark for comparing electron energies within various materials.
Electron affinity in semiconductors refers to the energy gap between the minimum of its conduction band and the vacuum level and it is a critical parameter in determining how easily a semiconductor can accept additional electrons.
