Abstract
Precision calculations in hadronic processes at high energy colliders are crucial for improving the understanding of the standard phenomena as well as for the discovery of new physics. Spinor-helicity formalism serves as one of the most efficient ways to simplify the calculations of matrix elements. In this article, we compute the matrix elements for the process mediated by photon and gluon. Ignoring the contribution of boson exchange, we show that the calculation of matrix elements for this process simplifies to a great extent by using spinor-helicity formalism.
