Webb20 juni 2016 · So the quarks can take positive and negative values of spin. The proton has spin norm $1/2$ because it has two $+1/2$ spin and one $-1/2$ spin quarks, or two $-1/2$ spin and one $1/2$, because this is the same value of the norm, but different projection. As to what is the particle with spin $\frac32$ — it is the so-called $\Delta_0$. The proton–proton chain, also commonly referred to as the p–p chain, is one of two known sets of nuclear fusion reactions by which stars convert hydrogen to helium. It dominates in stars with masses less than or equal to that of the Sun, whereas the CNO cycle, the other known reaction, is suggested by theoretical models to dominate in stars with masses greater than about 1.3 times that of t…
