[A1n_d2n] Jacobian question

[Xiaochao Zheng]

Dear All:

Just want to let everyone know that I found the answers, in fact two of them:

1) d^2 sigma/dx/dQ2 = (pi*nu) / (x*E*E’) d2sigma/dE’/dOmega

2) d^2 Sigma / (dE' dOmega) = (E E' / Pi) d^2 Sigma / (dnu dQ2)
d^2 Sigma / (dnu dQ2) = (2 M x^2 / Q2) d^2 Sigma / (dx dQ2)

Thanks to you all!

(PS: the two agree.)

Subject: [A1n_d2n] Jacobian question

Hi all:

Sorry to bother everyone, but does anyone have a well-derived (or a textbook equation) for the Jacobian to convert d^2sigma/dE'/dOmega into d^2sigma/dx/dQ2?

(I know the math, but would like to be lazy and skip 30min of derivation.)

Thanks in advance!
