Coalescence between a neutron and a K+ meson

  1. Aug 18, 2003 #1
    I think it is simply the coalescence between a neutron and a K+ meson. What are your thoughts?

    Looking at it's quark content (uudds) it's obvious it has the same quark content as a neutron and a K+ indeed those are the two particles it decays into, I'm not sure how it's formed though.

    I have read that it is formed when gamma rays are directed at a heavy hydrogen nuclei and what happens next is beyond me

    It is merely the coalescence of the neutron and the K+ meson. I believe that is what the original article on this read awhile ago.

    So if the pentaquark particle decays in to a neutron and a K+ meson then it is unstable. Would anyone happen to know its half life?

    IIRC it's thought to be about 10-20 which is pretty short even for an elementary particle.
