which make up composite
particles like neutrons and protons,
come in six “flavours” – up, down, strange,
charm, top and bottom – which give those composite
particles their properties. The weak interaction is unique
in that it allows for quarks to swap their flavour
for another. The swapping of those
properties is mediated by
the force carrier
What flavour are you, asked the left-handed particle, and how about you and I do the “half-integer spin,” as I like to call it?
I can see you’re not a “charmer,” she replied (was she a top, or bottom, or maybe a strange? he wondered) but perhaps we could try a little weak interaction, a little swapping of properties, if you know what I mean.
