Computational Physics and Python Applications

We calculate the production of two standard-model neutral Higgs bosons via bremsstrahlung from a single W or Z boson in pp or ${e}^{+}$${e}^{\mathrm{\ensuremath{-}}}$ collisions at supercollider energies. Observation of these processes would test the predicted HHH, HVV, and HHVV couplings (V=W or Z). For ${e}^{+}$${e}^{\mathrm{\ensuremath{-}}}$\ensuremath{\rightarrow}ZHH we extend previous cross-section calculations to a more comprehensive range of energies and Higgs-boson masses, that may be accessible to future machines; we also give final-particle distributions. In the pp case we present the first calculations of the processes pp\ensuremath{\rightarrow}HHVX; the cross sections are comparable to other double Higgs-boson production processes for a range of energies and masses. The presence of W or Z accompanying the Higgs-boson pair has distinct practical advantages for triggering and for separating the final state from backgrounds.
