Exotic Higgs Decay Benchmark Card Generator
A generator that converts the paper's Higgs-portal benchmark parameters into machine-readable 'benchmark cards' of exotic Higgs decay rates and width shifts, ready for collider experiments hunting hidden-sector particles.
Concept
A benchmark-card generator for collider hidden-sector searches. The tool scans the paper's benchmark parameter ranges and, for each point, computes the model's Higgs-portal observables: branching ratios and kinematics for exotic Higgs decays into the dark sector (mediator pairs and invisible final states) and the resulting shift in the total Higgs width. It emits machine-readable benchmark cards — masses, couplings, branching ratios, decay kinematics — in the formats collider collaborations use for search optimization and reinterpretation, so the model can be dropped directly into existing hidden-sector Higgs search workflows. The single wedge is: dark-matter benchmark in, collider-search input out.
Why now
The paper [0] explicitly comments on Higgs-portal phenomenology and provides benchmark parameter ranges consistent with the minimal framework — precisely the inputs needed to make collider predictions. Because the model's only connection to visible matter is the Higgs portal, exotic Higgs decays and Higgs-width effects are its leading collider observables, and the paper's framing as a phenomenological benchmark (rather than a complete ultraviolet completion) makes it exactly the kind of well-defined reference model that collider hidden-sector searches are designed to test. As LHC Run 3 hidden-sector analyses and Higgs-factory physics studies (CEPC, FCC-ee) ramp up, a dedicated generator for this benchmark fills a concrete gap.

AI assessment
A highly focused utility tool that converts theoretical parameters into experiment-ready data formats, though it faces a small total addressable market and potential overlap with existing open-source tools like SLHA.
- Evidence strength 4/5
- The research explicitly provides benchmark parameter ranges and discusses Higgs-portal phenomenology, which directly supports the creation of a calculator for branching ratios and width shifts.
- Market pull 2/5
- The target users are a small number of highly specialized physicists at a few global institutions who typically build these tools in-house or use open-source community standards.
- Novelty & moat 3/5
- While similar to the 'Detector Forecast Tool', this focuses on collider-side observables (decay rates) rather than direct detection (recoil spectra), filling a distinct part of the experimental pipeline.
- Feasibility 5/5
- The physics involved (branching ratios and width shifts for a minimal portal model) is computationally simple and can be implemented as a lightweight script quickly.
- Wedge clarity 5/5
- The wedge is extremely sharp: 'dark-matter benchmark in, collider-search input out,' avoiding any scope creep into simulation or analysis.
- Simplicity / focus 5/5
- The idea is a single-purpose generator with a clear input and output, avoiding the 'platform' trap entirely.
