Please teach me whether this is correct:(adsbygoogle = window.adsbygoogle || []).push({});

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
