sir, what is pi meson theory and quark theory? are they related? do neutron and proton have independent existence in a nucleus?

Answer:

Quark theory:

The quark theory proposes organizing particles into 2 quark particles (called mesons examples: the pion and kaon), 3 quark particles (called hadrons examples: the proton and neutron) and 5 quark particles (pentaquarks).  

There are 3 groups of quarks, Up/Down, Charm/Strange, and Top/Bottom, and each of these quarks has a corresponding anti-quark.  The proton is made of a combination of up, up, down quarks (with a mixture of quark and anti-quarks in the combination); while the neutron is made of up, down, down quarks.

Assuming that a quark is an elemental conscious particle produces a very complex system composing many different particles and particle types.  Such an assumption results in a theoretical system populated by far too many elemental particles, each of which would follow its own unique programmed laws of behavior.  

Thus, we shall postulate that the quark is a subatomic orbiting assembly of Negative and Positive DPs.  This system would allow any quark to exist which could maintain an identifiable level of stability, or what we shall call a resonant state.

The Standard Model proposes the bonding of particles as being mediated by exchange forces that hold these particles together.  In the case of the proton and neutron, the unit of exchange is the neutral Pi meson (aka: the neutral pion).  The pion is simply two quarks that are shared between the proton and neutron. 
when the proton and neutron are in sufficiently close proximity, they can share the ongoing oscillation of the pion.  

The bonding of proton and neutron is considered to be a manifestation of the strong force, but reframing the interaction as a sharing of particles shows that the Strong force is not a force at all,


The neutron decays into a proton, electron, and a neutrino, by a down quark converting into an up quark, and emitting an electron and neutrino.
