Do speeds of propagating of all interactions have the same value c?

[ndung200790]

Please teach me whether this is correct:
It seem to me that the velocity of propagating of all type of interaction is the same value c as the velocity of light.Because equation of propagating of phase p.x=0 leads to v=E/p^(where p^-modul of spacelike-momentum)=square(c)/v then v=c.Where p is 4-momentum of a quantum and p.x is phase of field operator.
Thank you very much in advance

It seems that even in case the transfer boson is massive,the velocity of propagation of interaction still is c,because of quantum characteristic.Is that correct?

<Speed of interaction> is a classical concept applicable to classical theories. (Gravitational and e-m waves traveling at c). However, the 4 interactions can be seen from a quantum perspective, where <speed of interaction> notion will no longer apply.

No.

Then classical saying the week interaction has the small interaction velocity,because of massive transfer boson?

Yes.
