If two scalar mesons interact through a Yukawa interaction, the potential between the two particles will be:
which is the same as a Coulomb potential except for the sign and the exponential factor.
This looks wrong to me. Shouldn't it be "If two fermions interact through..." ?

THIS ARTICLE NEEDS REVISION! "Yukawa particle has spin zero and even spin always results in an attractive potential." This statement makes no sense. What about a coulomb bound pionic atom? —Preceding unsigned comment added by 66.45.143.210 ( talk) 17:15, 17 November 2008 (UTC)
For a ( renormalizable) self-interacting field, one will have
Is this the only possibility (even accounting for non-polynomial V)? Might be nice to reference the proof.
I'm removing the merge tag. Its been there two years, there's no discussion, no proposal. The strong interaction article is non-technical; this article is highly technical. At any rate, we know that the strong interaction is not just pions, we know that pions are just an approximation. 67.198.37.16 ( talk) 01:03, 5 September 2015 (UTC)

The second paragraph of the classical potential section discusses the exponential term in terms of instabilities and the radioactive decay of the mesons. It should be made clear at the minimum that this radioactive decay has nothing to do with the decaying of real pions -- about 10-16 seconds for neutral, and 10-8 seconds for charged. Both of these time-scales are far too long (by orders of magnitude) to notice in the nucleus.
The quantity μ in the exponential is the particle's mass (ħ = c = 1). The potential is the solution of the Klein-Gordon equation with zero time-dependence -- the meson is far off the mass shell. — Preceding unsigned comment added by Johnm307 ( talk • contribs) 00:56, 5 February 2021 (UTC)
