Is there an equation for the strong nuclear force?
The equation describing the force due to gravity is $$F = G \frac{m_1 m_2}{r^2}.$$ Similarly the force due to the electrostatic force is $$F = k \frac{q_1 q_2}{r^2}.$$
Is there a similar equation ...

The charge of an electron is a constant. In any case? [closed]
Since Millikan it is obvious that the charge of the electron can be measured as a result of the force exerted by an external electric field. What we get in detail is the charge from the excess of ...

Why do the quarks constantly change colors?
In a hadron the quarks constantly change colors.They,then exchange gluons to remain color neutral.For example a red quark becomes blue by emitting a red and anti blue gluon and then the blue quark ...

Why can the Euler beta function be interpreted as a scattering amplitude?
The Wikipedia article on the Veneziano Amplitude claims that the Euler beta function can be interpretted as a scattering amplitude. Why is this?
In another word, when the Euler beta function is ...

Why does the quarks binding energy add mass to nucleons instead of reducing it? [duplicate]
The mass of nucleons is bigger than the sum of the masses of its constituent quarks. I understand that it's because you have to take into account the binding energy of these quarks.
What I don't ...

Does strong interaction care about mass? (+ Isospin question)
So in the journey of trying to understand more about the strong interaction I have encountered some passages linking mass with strong interaction. Like from Greiner and Müller Quantum Mechanics - ...

Cause of Strong force
What is the origin and cause of the strong interaction which occurs between the nucleons? I have read that it is caused by the exchange of mesons but what then ultimately causes this meson exchange to ...

Can strong interaction be repulsive?
I know that the repulsion between nuclei is mostly caused by electrostatic repulsion and Pauli's exclusion principle. But in the sub-nucleus level, is there a condition where the strong interaction ...

Is there strong interaction between electrons?
I am not familiar with quantum mechanics at all. But I remember when I was at high school, we learned that strong interaction keeps protons next to each other while they repel each other because of ...

Strangeness of elementary particles
What is the property, whose violation led to the assumption of strangeness? Prior to the discovery of strangeness was it assumed that particles that are produced by strong interactions can decay only ...

Do hadrons only interact via strong interaction?
According to my revision guide baryon and mesons always interact via the strong interaction.
Does this hold for baryon-baryon interactions? meson-meson?
Thanks

Do all hadrons experience the strong nuclear force?
In nuclear physics, nuclear force, also known as the residual strong force, is mediated by pions exchanged between protons and neutrons. It doesn't seem like this should be limited to protons and ...

Relation between Strong Forces and Binding Energy
The definition of Strong Force is the force that binds the quarks into the protons and neutrons, and spills over around each proton and neutron and is an attractive one.
And Binding Energy is the ...

Does the J/$\Psi$ primarily decay into real gluons?
so apparently the this cool looking decay of the $J/\Psi$ particle is OZI suppressed, which was confusing to me, because the Particle Data Group (link) says that 64% of its decays are into 3 gluons (...
