Why were spin and discovery date removed from the table?
How can the quark "makeup" contain a root - we are talking about particles, no?
Yep, but the type of particle is just a property of its state. For something like an electron, there's really nothing else that matches the charge and the like, so you get a pure state. But an up-antiup and a down-antidown are just different versions of the same thing, so real states are mixes of them, somewhat like molecular orbitals.
- Why is the subtraction then? --Kenny TM~ 12:55, Nov 25, 2004 (UTC)
- That's a phase. If you have two possible values, that a quantum entity can have, you can superpose them with a different phase relative to each other. That's a bit hard to explain in an illustrative way but maybe this helps: If you want to use the formalism of quantum mechanics to calculate some property, and you now how to calculate the property for a basis state, the what should you do if you have a superposition of two basis states? Should you add the values, or subtract them, or what? Well, the phase and the <math>\sqrt{2}<math> shows you how to combine the individual values. So, we are not subtracting two quarks. The '-' is merely indicating that properties of the individual quark types have to be subtracted to get the value of the superposition. Simon A. 13:12, 25 Nov 2004 (UTC)
Actually, if you think about it, the "makeup" listings are only valid in the limit in which the up, down and strange have zero mass and the charm, bottom and top have infinite mass. Perhaps this should be clarified somehow? -- Xerxes 19:56, 2005 Feb 3 (UTC)
Is the "famously corrected" part correct? I thought the original word "mesotron" was from the Greek root meso- plus the ending from "neutron" and "electron". Was the actual "correction" more like pointing out that the suffix in "neutron" and "electron" is just -on, not -tron? -- Anonymous, 04:40, 17 June 2005 (UTC)
