# Correlations in Spin-Singlet states

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
In (b), if particle B has up spin (x-axis), then A should have down-spin(x-axis). The problem ask the state by using lma,mb> state.
This state is valid only in z-axis, but how can i represent that state ??
I think the answer is the same with (a) regardless of the x-axis measurement

Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.

You could try changing to the basis of eigenkets of $J_x$ and then changing back.
