# Top quark and matter-antimatter

• sontag
In summary, Quarks are not only defined by color, but electric charge and weak isospin. So another kind of particle is required. This is called techicolor.

up quark and down quark

An up quark has a smaller mass than a down quark.
Is it possible that an up quark is made from 2 antidowns with energy being released?

Composite models, techicolor, topcolor etc. It is assumed that the top quark is a condensate of some other particle (not other quark). A lot of work done. No idea about how it relates to matter/antimatter symmetry (antimatter is always likely to anhiquilate against matter).

ARIVERO:

SONTAG:
So two colour charges can't come together and form one colour charge
by releasing some energy that carries a second colour charge?

well, quarks are not only defined by colour, also electric charge and weak isospin. So another kind of particle is required. This is called techicolor.

An up Quark has more fractional Charge than a Down Quark..
UP 2/3 charge Down 1/3 Charge

2/3..'two thirds' of a down composite Quark..does not equal..2/3s of an Up Quark.

Matter prevails over Anti-Matter..there are I believe experiments underway at CERN:http://www.exploratorium.edu/origins/cern/ideas/antimatter.html
which are hoping to uncover if the 1/3 fractional charge of ordinary Protons, represents 'Negative' matter, and it may be that the Anti-Matter Anhilations, will show this to be so?

For instance the Matter >>Antimatter anhilation spectrum, might reveal the energy released to be 'less or more' than the reversed interaction of Anti-Matter .>> Matter interactions.

The fact that fractional charge has the configuration it has 1/3 + 2/3..is a remnant of early Universe interaction..it does not balance out..for instance if Quarks had a Fractional Charge of 1/4 +1/4..this would be perfectly symmetrical..and matter could not prevail over Anti-Matter?

## 1. What is a top quark?

A top quark is a fundamental subatomic particle that is one of the six types of quarks. It is the heaviest known elementary particle and has a mass of approximately 173 GeV/c2.

## 2. How was the top quark discovered?

The top quark was discovered in 1995 at the Fermi National Accelerator Laboratory (Fermilab) in Illinois. Scientists used a particle accelerator called the Tevatron to collide protons and antiprotons at high energies, producing top quarks that could be detected by their decay products.

## 3. What is the significance of the top quark in matter-antimatter symmetry?

The top quark plays a crucial role in the matter-antimatter asymmetry problem in the universe. According to the standard model of particle physics, matter and antimatter should have been created in equal amounts during the Big Bang. However, there is a slight excess of matter, and the top quark is thought to be responsible for this imbalance.

## 4. How is the top quark related to the Higgs boson?

The top quark has a strong connection to the Higgs boson, which is a fundamental particle that gives mass to other particles. The top quark's mass is closely related to the strength of its interaction with the Higgs field, making it an essential piece of the puzzle in understanding the origin of mass in the universe.

## 5. How is the study of top quarks relevant to everyday life?

Although the study of top quarks may seem far removed from our daily lives, it has many practical applications. For example, the technology used to detect top quarks in particle colliders has also been used in medical imaging devices like PET scans. Additionally, understanding the properties of top quarks could lead to advancements in technology, such as more efficient computer processors.
