I am curious to know if there exists a spin-1/2 hadron that is composed of three up quarks. I understand that in quantum chromodynamics, baryons are formed of three quarks, each carrying a distinct color charge to ensure color neutrality. Given that the Pauli Exclusion Principle necessitates distinct quantum states for each quark, is there a configuration where three up quarks could form a color-neutral baryon with a total spin of 1/2?
I am aware of the Δ++ baryon, where three up quarks with aligned spins result in a total spin of 3/2. However, I am wondering if there is a known baryon configuration with three up quarks that results in a total spin of 1/2.
