02 Jun 05 - 09:12 AM (#1498139) Subject: BS: Gluon! Off my leg, dammit! (non-bawdy) From: Rapparee A new baryon, which has been named Θ+, is being hailed as the first manifestly exotic hadron. Its charge is +1, and its mass, about 1540 MeV, roughly 60% more than the proton's, is quite ordinary for a baryon. But its observed strong decay to a neutron plus a K+ meson marks it as something radically new. A three-quark baryon couldn't possibly decay that way. Quarks come in six flavors. In increasing mass, the quarks are called: up (u), down (d), strange (s), charmed (c), bottom (b), and top (t). Except for the ultramassive t quark, which doesn't live long enough to form hadrons, each one resides in dozens of well-attested mesons and baryons. Because three quarks make a baryon, we say that each quark has baryon number B = + 1/3. For antiquarks, B = - 1/3. The strong interactions never change a quark's flavor, and net B is strictly conserved in all known physical processes. What makes the Θ+ exotic is the fact that the s quark has strangeness S = -1, that is, the same strangeness as the K- meson. There are many baryons with negative strangeness that couple to the K-. But to get S = +1, the strangeness of the K+, one needs the antistrange quark s-, and the s- has negative baryon number. So the fewest quarks that could constitute an S = +1 baryon is five. For charge +1, this "pentaquark" configuration would be uudds-. (The electric charge of the u is +2/3; the d and s quarks have charge -1/3, and antiquarks have the opposite charges.) |

So how can you have a three quark particle? Three is not a pair or a multiple of pairs! No wonder Gluon gets confused! |

The new particle of cause will have a five fold rotational symmetry, which if I'm not mistaken would lead to 5 to the 5 Rupert vectors, giving a Bose-Einstein condensate of them the unique property of negative temporal resonance at the flux centre if the mass/charge Eigen functions are normalised for Stradler bifurcation.

All that negative temporal resonance in one place can't be very good for the normal continuum. It's gonna blow a wormhole into the past or somp'n. Fun to mess with, if you survive. A |

I am only capable of saying "QUARK!!!". It's because I'm a duck/dog. It's a cross between "QUACK!!!" and "BARK!!!" However, I am able to impart a tremendous amount of information for a duck/dog with a one-word vocabulary, as is evidenced by this rather lengthy translation.) |

Me and my cousin Jimmy up front and my buddy Jim in the back seat. My cousin is one of the foremost aerospace engineers in the world. His specialty at that time was composite skins for high speed military aircraft. He was explaining computer simulation of tau shear in flexible carbon/metal based composites to me. I was not up to snuff on the high level math he was tring to impart to me, but I was keeping up and we had a lively discussion. At a lull, Jim spoke up and said, "You know I'm deaf in my right ear eh? So shut the fuck up because it's goin' in my left ear and gettin' stuck!!" |

The dog who isn't a dog but a duck dog has created a pond for it's duck self, and forgetting it's quarkiness while paddling for freedom from it's dog self. (The Bernoulli Equation can be considered to be a statement of the conservation of energy principle appropriate for flowing fluids. The qualitative behavior that is usually labeled with the term "Bernoulli effect" is the lowering of fluid pressure in regions where the flow velocity is increased. This lowering of pressure in a constriction of a flow path may seem counterintuitive, but seems less so when you consider pressure to be energy density. In the high velocity flow through the constriction, kinetic energy must increase at the expense of pressure energy.) |
