Hi there,
I have a a partial decay width in form of ## \frac{d \Gamma}{d \cos{\theta}~ dq^2} = ## some terms functions in q and ## \theta ## variables.
How to integrate this decay width in Mathematica over this two variables ?
I tried some thing like
j[q_]:= ## \int_{1}^{-1} ## Gam[q, ## \theta ##] d Cos[## \theta ##]
then
## \int_{0}^{10} ## j[q] dq^2
But it gave me errors
Cos[## \theta ##] is not a valid variable.
Integrate::ilim: Invalid integration variable or limit(s) in {q^2,0,10}. >>
I also tried to use NIntegrate..
So any help in that ?
Cheers,
S.
