We know "asymptotic freedom" says that the interaction between particles, such as quarks, becomes arbitrarily weak at ever shorter distances and stronger with range The quarks are connected like being on a rubber band: (string) I have the following questions: 1) While the quarks get more seperated on their stretching string, can you say (theoretical) that this string is really getting thinner, or getting narrower, just like real elastic? 2) If you compare, theoretical, the situation of 1) increasing distance and 2) decreasing distance between quarks, what can you say about the amount of energie in between them: a) Does this amount of energie depend on the number of interactions between the quarks and the gluons, and when the answer is yes, which are the most important? And when no, where does it depend on really? And when the answer is Yes, that means less reactions when the distance get's shorter. But at shorter distance the thermal pressure will rise enormously Can we say that this thermal pressure "from outside" has no effect on the quarks? Has this pressure effect on something else? ( I always learnt: more pressure means more particle-movement, but the quarks seem to move in total freedom, does their movement only depend on their own gluon-string-energy?) Cn we maybe say that the energy on the quantum-gluon-elastic is negative related with the pressure outside? Kind regards, maxmax.
