Pentaquarks 36
jafuser writes "Physicists are quite confident that they have discovered a new baryonic state called a 'pentaquark' which is a particle composed of *five* quarks (4 quarks and one anti-quark to be precise). Up until now, quarks were only observed to come together in groups of two (mesons) or three (baryons). If you still haven't gotten comfortable with knowing your leptons from your hadrons, I suggest clicking through an excellent site at Particle Adventure."

and if you read enough Frijtof Capra, youll find out about the zen-tastic yin and yang of the particle known as the "waxon", and its complement - the anti-waxon.

You'll also find that, if you study the entire faculty and staff, you'll discover that they are actually made of individual particles called "persons".

RGB plus R!R or G!G or B!B.
Think of this as a merged baryon and meson.

No. They specifically said that the merged version would have different properties.

"Merged" != "Bound".
A bound pair would not be a distinct particle (it would be two co-orbiting, which would have different particles). A pentaquark can be thought of has a merger of the two particles, containing the constituents of both but having its own energy structure.
List of the constituents is the same. Hence, my example.

In principle, we can get any number we please. The question is whether a particle with, say, 7 quarks would have lower energy than three separate particles (one baryon and two mesons). Depending on its internal energy structure, it would either be unstable, extremely unstable, or not bound as a particle at all (we know it's not stable because a) we don't see these around normally, and b) anything built from quarks and antiquarks decays [quickly if the Q a
