About PP-Chain

The proton-proton chain is the dominant fusion process in stars like our Sun. It converts hydrogen into helium through a series of steps, releasing 26.7 MeV total. Temperature required: ~15 million K.

Proton (uud)

A proton consists of 2 up quarks and 1 down quark held together by gluons (the carriers of the strong force). Each quark carries a color charge (red, green, or blue). The combination must be "color-neutral" (white). Gluons constantly exchange between quarks, creating flux tubes of confined energy.

Quark Properties

Up Quark (u)+2/3 e, 2.2 MeV
Down Quark (d)-1/3 e, 4.7 MeV
Gluons (g)0 charge, 0 mass

The Strong Force

The strong nuclear force is ~137x stronger than electromagnetism. It binds quarks into hadrons (protons, neutrons, mesons). Unlike other forces, it gets STRONGER with distance - quarks can never be isolated (confinement). Virtual quark-antiquark pairs constantly appear and disappear in the vacuum.
