HiggsJetAmplitude

class HiggsJetAmplitude

Coherent W/Z and infinite-top Higgs-plus-jet observables in the effective model’s basis. Construction reuses the supplied model for generation, display, and contraction. Cancellation is checked between native stages; an active HEPKit or Idenso operation completes before acknowledging a cancellation request.

Evaluate normalized W1..W4 and Z1..Z4 form factors and their absolute allowances. Model parameters are exact Symbolica expressions; model float defaults are unused. Coefficients must use the same physical kinematics and W/Z masses as the model inputs. Includes incoming spin/color averages and final-state sums, with no phase-space factor.

with_form_factor_vertices

HiggsJetAmplitude.with_form_factor_vertices(model: Model) -> Model

Related type: Model

Add the symbolic W, Z and HEFT gggH vertices to an existing Standard Model. Returns a native HEPKit model retaining its existing particles, parameters and interactions. Numerical form factors still come from loop evaluation; conflicting declaration names are rejected rather than overwritten.
