Technicolour physics - understanding the basics

Higgs particle?In summary, the conversation discusses the concept of technicolor theories, which are models of physics beyond the standard model that address electroweak symmetry breaking and the mass of elementary particles. These theories are based on quantum chromodynamics and aim to explain the mass of W and Z bosons through new gauge interactions instead of introducing Higgs bosons. However, there seems to be a lack of textbooks that explain the concept step by step.

I'm having trouble with the following:

technicolour predicts new massless techniquarks.

The technicolour force breaks the chiral symmetries of these quarks and goldstone bosons emerge. But goldstone bosons are massless? Goldstone bosons are eaten by W and Z and thus W and Z acquire mass.

This would make sense to me if the emerging Goldstone bosons were not massless... Could anyone clarify?

Technicolor theories are models of physics beyond the standard model that address electroweak symmetry breaking, the mechanism through which elementary particles acquire masses. Early technicolor theories were modeled on quantum chromodynamics (QCD), the "color" theory of the strong nuclear force, which inspired their name.

Instead of introducing elementary Higgs bosons to explain observed phenomena, technicolor models hide electroweak symmetry and generate masses for the W and Z bosons through the dynamics of new gauge interactions.

Do you know a textbook where idea of technicolors explain step by step? All reviews what I have seen start from a advance detail, and no one explain group representation, Lagrangian and so on. Which equation they use for determine a mass
 

1. What is Technicolour Physics?

Technicolour physics is a branch of physics that focuses on understanding the principles and mechanisms behind the production, manipulation, and perception of colour.

2. How does light interact with matter to produce colour?

Light interacts with matter through a process called absorption and emission. When light hits an object, some of its wavelengths are absorbed by the atoms in the material. The remaining wavelengths are reflected or transmitted, which our eyes perceive as colour.

3. What is the difference between additive and subtractive colour mixing?

Additive colour mixing involves combining different wavelengths of light to create new colours. This is how computer screens and TVs produce colours. Subtractive colour mixing, on the other hand, involves combining pigments or filters that absorb certain wavelengths of light to create new colours. This is how printers and paint mix colours.

4. How does the human eye perceive colour?

The human eye has cells called cones that are sensitive to different wavelengths of light. There are three types of cones that are sensitive to red, green, and blue light. When these cones are stimulated, our brains interpret the combination of signals as different colours.

5. How do colours affect our emotions and behavior?

Colours have been shown to have a direct impact on our emotions and behavior. Different colours can evoke different feelings and reactions, and they can also influence our mood and perception. For example, warm colours like red and orange can stimulate energy and passion, while cool colours like blue and green can promote calmness and relaxation.
