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?

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.
 
Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
The value of H equals ## 10^{3}## in natural units, According to : https://en.wikipedia.org/wiki/Natural_units, ## t \sim 10^{-21} sec = 10^{21} Hz ##, and since ## \text{GeV} \sim 10^{24} \text{Hz } ##, ## GeV \sim 10^{24} \times 10^{-21} = 10^3 ## in natural units. So is this conversion correct? Also in the above formula, can I convert H to that natural units , since it’s a constant, while keeping k in Hz ?
