This tool is intended for the visualization of different models of dynamics so we ultimately want to be able to switch between the various models using the UI.
The following is true for all models:
Forces: There is a centrifugal force on the quarks as the orbit with some momentum. There is the color charge force (strong force) which is the flux tube that brings the quarks together. There is electricity and magnetism that are applied to all of the charged quarks. The string tension should go as 1/r where r is the distance.
FluxTubes: Quarks are All Models: Valence quarks are connected via the flux tube. The flux tube can be modeled as just a string holding the valence quarks together. The three valence quarks should be orbiting around the center of the proton with a momentum that wants to send them flying off but the string tension of the flux tube keeps them bound. Both the The string tension and the valence quark momentum should be control parameters that can be changed in the UI. When the proton is polarized the orbital motion is correlated to the proton's spin when the proton is not polarized the spin direction is chaotic. The up quark and the down quark rotate in opposite directions. The up quark has a mass of about 2 MeV while the down quark has a mass of about 4. The string tensionshould go as a/r where r is the distance it stretches and 'a' is just a constant that we can change. 8 MeV so the up quark is about 2.4 times faster than the down quark. The momentum of the quarks is faster when the quarks are closer together in the center of the proton and slow when they are farther apart.
Gluons: Each Gluon has two colors as indicated on the Wikipedia page under Color Charge. All combinations of gluon colors should be represented. There are three colors and three anti-colors red, gluon, blue, and anti-red, anti-green, and anti-blue. You can use the same color representation as what you see on Wikipedia. Each gluon can float around and interact with other gluons. Gluons can do nothing, attract one another and annihilate turning into two photons. They can only annihilate if the total color charge of the two gluons is color-neutral. They can also interact with each other to make pure gluon states. Other than that all they do is swarm around and interact with the quarks. When they make contact, they can bounce off each other changing from attracting to repelling, or they can pass right through each other. When the gluon density is large more sea quarks pop in and out of the vacuum. Space is full of fluctuating waves/swarms of gluons increasing and decreasing the likelihood of QCD making something happen. The gluons continuously pop in and out of existence but the swarm is always present.
Quarks: The quarks are charged so besides the color force there is an electromagnetic force as well. This is true for the sea quarks and valence quarks. The Up quark has a charge of +2/3, and the Down quark is -1/3. This is important in the physics of their dynamics because when charges move, they make magnetic fields. The force from the electromagnetic charge scales as 1/r^2, where r is the distance between the quarks (charges). The color force on the other hand does not diminish as fast over distance, it is the same between quarks but will normally only act between two (sea-quarks) or three (valence quarks). The strength of the color force is roughly 137 times that of the electromagnetic force.
UI and Controls:
We also want a nice User Interface that is transparent so you can still see what's going on behind it and provides the option of controlling all of the dynamics and
