Hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

If I have a [tex]\Sigma[/tex] triplet of baryons, how do I calculate the EM and gravitational binding energy of these baryons? (assuming there is 1fm of distance between quarks and that each quark has 1/3 the mass of the [tex]\Sigma[/tex]),

I guess I have to use the EM and Gravitational Potential Energies for this.

Will be ok using the Rydberg Energy Formula for thr EM binding energie?

[tex]E = \frac{1}{2} {\alpha}^2 (\mu {c}^2)[/tex]

With [tex]\mu[/tex] being the reduced mass.

And what about the Gravitational thing? (just U = G m1m2 /r ?)

Thank you.
