Compute the Higgs likelihood (-2 log L) for a given set of reduced couplings or signal strengths. This is the primary analysis function that compares theoretical predictions against LHC experimental data.

Compute the Standard Model likelihood as a reference point. Returns -2 log L for SM couplings (all C = 1).

Compute the p-value for a given model compared to the Standard Model or best-fit point.

Perform a 2D parameter scan (e.g., CV-CF plane) and return likelihood values for contour plotting.

Perform a 1D parameter scan and return likelihood profile.
