Source of Soft Gluons: Questions & Answers

[Higgson]

When two high energy nuclei collide with each other, the hard and soft gluons
"hidden" in their wavefunctions are freed. Then the produced system of
the hard gluons begins to interact with the system of the soft gluons.

Sometimes the system of the soft gluons is called the low energy source which
feeds in energy to the system of energetic hards gluons. In this case, the soft
gluons from the low energy source comes into the system of hard gluons spherically
and symmetrically in the phase space.

As I know this radiation of the soft gluons is generally considered constant in time.
I need to know why ?

And I wish to know why the system of the hard gluons should be inside the system
of the soft gluons (since the soft gluons are incoming from all directions)?

Does anybody know the answers to these questions ?

I can provide some insight into these questions.

Firstly, the radiation of soft gluons is generally considered constant in time because the energy of the soft gluons is much lower compared to the energy of the hard gluons. This means that the soft gluons have a much longer lifetime and therefore their radiation is spread out over a longer period of time. Additionally, the interaction between the hard gluons and the soft gluons is a continuous process, meaning that soft gluons are constantly being emitted and absorbed by the system of hard gluons. This results in a constant flux of soft gluons, leading to a constant radiation in time.

As for why the system of hard gluons should be inside the system of soft gluons, it is important to understand that gluons are massless particles and therefore can travel at the speed of light. This means that they can come from all directions and interact with the system of hard gluons. However, the soft gluons are more likely to interact with the hard gluons that are closer to them in space, due to the inverse square law of force. This results in a spherical and symmetrical distribution of soft gluons around the system of hard gluons.

I hope this helps to answer your questions. The behavior of gluons is a complex topic and there is still much research being done to fully understand their interactions. If you have any further questions, please feel free to ask.

The radiation of soft gluons is considered constant in time because it is a continuous process. When two high energy nuclei collide, the hard and soft gluons are freed from their wavefunctions and begin to interact with each other. The soft gluons act as a low energy source, constantly feeding energy into the system of hard gluons. This continuous flow of energy results in a constant radiation of soft gluons.

As for why the system of hard gluons should be inside the system of soft gluons, it is because the soft gluons are incoming from all directions and surround the hard gluons. This allows for a more efficient exchange of energy between the two systems. Additionally, the soft gluons are necessary for the stability and evolution of the system of hard gluons.

I am not sure about the exact answers to these questions as they involve complex concepts in quantum chromodynamics. However, I hope this explanation helps to provide some understanding of the role of soft gluons in high energy collisions. Further research and study in this area may provide more detailed answers.
