i found that in the 3 W-W exchange of 4-fermion interaction of weak decay of Neturon beta-decay process and also this happens in scattering process,is there will be a gap or a channel between two particles?
thanks a lot!mfb said:There is no gap. You can rearrange the lines arbitrarily (as long as the connections stay the same) and physics does not change, this is just the most convenient way to graph it.
"Channel" refers to a specific Feynman diagram or a class of Feynman diagrams.
The concept of touching does not make sense for elementary particles. They do not have a size, and they do not have an exact position.
It is highly unlikely that two particles will ever touch each other. According to the laws of physics, particles are surrounded by a repulsive force called the "Pauli exclusion principle" which prevents them from getting too close.
If two particles were to come into contact with each other, they would experience an incredibly strong force that would cause them to repel each other. This is due to the electromagnetic force between the particles.
No, two particles cannot merge together. Each particle has its own unique properties and characteristics that cannot be combined with another particle. They will always maintain their individual identities.
In certain extreme conditions, such as in a black hole or during a high-energy particle collision, particles may come close enough to touch each other. However, this is a rare occurrence and does not happen in everyday situations.
Scientists use various methods such as particle accelerators and detectors to study the behavior and interactions of particles. They also rely on theoretical models and mathematical equations to understand the properties of particles without physically touching them.
