A What is the meaning of chiral-odd/chiral-even functions

  1. Apr 25, 2016 #1
    I read about quark distribution functions in the nucleon that are chiral-odd or chiral-even functions (Sivers function, Boer-Mulders function and other distribution function related to nucleon transversity). What is the definition of chirality for functions? Does this mean they are odd or even under the transformation (t,x,y,z) -> (t,-x,-y,z) ?

    Thanks!

    Thank you. So in better terms than what I used, it means that when one switches the right handed quarks in a nucleon with the left handed ones, a chiral-odd distribution function switches its sign while a chiral-even one retains its sign. Is that correct?

    Off the top of my head, that would be what I'd expect.
    I'm thinking you should relate this to your course-notes and text here though... I may not have the same idea of a "distribution function" that your prof has.
