An analytic result for the amplitude

John M. Campbell, Giuseppe De Laurentis, R. Keith Ellis

We present a fully analytic calculation of the leading-order one-loop amplitude for triple Higgs production via gluon fusion, , retaining full dependence on the mass of…

Analytic reconstruction with massive particles: one-loop amplitudes for

John M. Campbell, Giuseppe De Laurentis, R. Keith Ellis

We present an analytic reconstruction of one-loop amplitudes for the process . Our calculation is a novel use of analytic reconstruction, retaining explici…

Projection-to-Born-improved Subtractions at NNLO

John Campbell, Tobias Neumann, Gherardo Vita

While the current frontier in fixed-order precision for collider observables is NLO, important steps are necessary to consolidate NNLO cross-section predictions with improved s…

Analytic amplitudes for a pair of Higgs bosons in association with three partons

John M. Campbell, Giuseppe De Laurentis, R. Keith Ellis

The pair production of Higgs bosons at the LHC can give information about the triple Higgs boson coupling. We perform an analytic one-loop calculation of the amplitudes for a pair…
