    Meson Neutron
AI Thread Summary
The discussion centers on the formation and decay of the pentaquark particle, which is suggested to result from the coalescence of a neutron and a K+ meson. Participants agree on the quark content similarity between these particles, noting that the pentaquark decays into a neutron and a K+ meson, indicating its instability. There is mention of gamma rays interacting with heavy hydrogen nuclei as a potential formation process, though details remain unclear. The half-life of the pentaquark is estimated to be around 10^-20 seconds, which is considered very short for an elementary particle. Overall, the conversation highlights the complexities surrounding the pentaquark's existence and decay characteristics.

I think it is simply the coalescence between a neutron and a K+ meson. What are your thoughts?

sounds logical
 
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 into 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.
