SUMMARY

The discussion clarifies the differences between baryons, specifically focusing on the quark combinations in protons and delta baryons. A proton consists of two up quarks and one down quark, resulting in a total spin of 1/2. In contrast, delta baryons, which also contain two up quarks and one down quark, have a total spin of 3/2. The distinction in spin is a critical factor that differentiates these particles, despite their similar quark content.

this isn't really a problem, just a question.
with baryons, what exactly is the difference between the different quark combonations?
for example, a proton had two up quarks and a down but so does the delta, or one of them, i guess. shouldn't that mean that they are the same particle?
how are they different?

none

The Attempt at a Solution



the only thing i could thing of was the different order that the quarks are it, or a difference in spin. it wouldn't be a difference in charge, though, because the fractional charges in the quarks are what determines the charge of the whole particle, right?

The three quark spins in the nucleon add up to spin 1/2,
and to spin 3/2 in the Delta.
