Interactions and particles

  1. May 19, 2007 #1
    Whenever a process yields a photon, an electromagnetic interaction is involved. If a neutrino comes out, a weak interaction is responsible. Is there any way to see from the ingoing and outgoing particles if a strong interaction is involved?

    if isospin and strangesness is conserved, you must have a strong intercation. Weak do not conserce strageness and EM do not conserve isospin.

    Ah great, not as easy to figure out as for the other interactions but very helpful. Thanks!

    And also the strong interaction is much much more probable than the weak in those cases when conditions of both strong and weak are fullfilled.
