Parameters:
  • sigma_pt – Parton cross section

  • alpha – Fine structure constant

  • Q – Mass of the electron pair (virtual photon)

  • sum_e_q_squared – Sum of electric charges of quarks squared

Returns:

\(\sigma_{pt} = \frac{4 \pi \alpha^{2} sum_{e q squared}}{Q^{2}}\),

\sigma_{pt} = \frac{4 \pi \alpha^{2} sum_{e q squared}}{Q^{2}}

Parameters:
  • sigma – Cross section

  • sigma_pt – Parton cross section

  • x_1 – Quark momentum fraction

  • x_2 – Antiquark momentum fraction

  • alpha_C – Colour charge

Returns:

\(\frac{\frac{d^{2}}{d x_{2}d x_{1}} \sigma}{\sigma_{pt}} = \frac{2 \alpha_{C} \left(x_{1}^{2} + x_{2}^{2}\right)}{3 \pi \left(1 - x_{1}\right) \left(1 - x_{2}\right)}\),

\frac{\frac{d^{2}}{d x_{2}d x_{1}} \sigma}{\sigma_{pt}} = \frac{2 \alpha_{C} \left(x_{1}^{2} + x_{2}^{2}\right)}{3 \pi \left(1 - x_{1}\right) \left(1 - x_{2}\right)}
