Hello everyone--I was hoping someone could give (or refer to) a textbook definition of a [tex]c[/tex]-number, as used in the context of quantum field theory.
Does this refer to a commuting number? I've also read it referring to a classical quantity. classical quantity, from a not-very-reputable source. (Though are these the same?)
If the 'c' refers to commuting, when I read something like "...spinors are anti-commuting (c-numbers)." (Bailin and Love, SUSY book) Does this mean that spinors are anti-commuting objects composed of commuting numbers? (It certainly doesn't mean that the spinors themselves are commuting...)
Thanks,
Flip
