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…

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…
