Hi all
I found http://en.wikipedia.org/wiki/Cross_section_(physics)#Relation_to_the_S_matrix" on wikipedia:
[tex]{d\sigma \over d\Omega} = (2\pi)^4 m_i m_f {p_f \over p_i} |T_{fi}|^2[/tex]
Has it the dimension of a surface? (I only see M*M)
It is the first time I read this formula about differential cross section.
