gg → Z Z: analytic two-loop results for the low- and high-energy regions
Abstract We compute next-to-leading order virtual two-loop corrections to the process gg → Z Z in the low- and high-energy limits, considering the contributions with virtual top quarks. Analytic results for all 20 form factors are presented including expansion terms up to 1 / m t 12 $$ 1/{m}_t^{12}...
