Spinor-helicity calculation of the $g^{\ast }{g}^{\ast }\to q\overline{q}{V}^{\ast }$ amplitude at the tree level

Jan Ferdyan, Błażej Ruba

We compute amplitudes for the process $g^{\ast }{g}^{\ast }\to q\overline{q}{V}^{\ast }$ (two virtual gluons into a quark, antiquark and a boson) at the tree level using the spinor-helicity formalism…
