Homework Help: Asking on violation of bell's inequality and classical probability in a two-photon co

  1. Jan 12, 2010 #1
    1. The problem statement, all variables and given/known data

    Currently I'm reading your paper entitled "violation of bell's inequality and classical probability in a two-photon correlation experiment" Physical Review Letters, Vol61,article 50 (4July1988)
    http://wwwphy.princeton.edu/~kirkmcd/examples/QM/ou_prl_61_50_88.pdf" [Broken]

    When I read this paper, I then stuck with equation no.5a(page51), I try to insert equation(2) and equation(3) into equation (4), but i only come to:
    P(theta1,theta2)=K ( ( TxTy ) ( cos(theta1) )^2 ( sin(theta2) )^2 + (RxRy) ( sin(theta1) )^2 ( cos(theta2) )^2

    2. Relevant equations

    see equation(3) (4) and (5) in pages 51

    3. The attempt at a solution

    I try many times but I still got the same answer, I'm really desperate to know how to got equation(5a) because in my derivation I didn't get any (TxTyRxRy)^(1/2)cos(theta1)cos(theta2)sin(theta1)sin(theta2) terms...
