Simulator
Choose among three distinct calculation modes: the 5D builder model, a top-KK Higgs-production reference, or the 4D neutrino-ring research model.
Control names are kept as they appear in the application. Start with a reference, change one input at a time, and retain the assumptions with your result.
What this tool is for
Use this page as the entry point for calculated masses and experimental comparisons. First identify the model you want to study. The builder mode follows the shared SU(N) input; the Higgs-production mode isolates a top-KK contribution; the neutrino mode studies a separate four-dimensional construction. Thermal and flavour experiments have their own inputs even when they appear on the same page.
First steps
- Choose Model to calculate and read the mode's own guide.
- Start from a named reference or the restored default before changing one input.
- Read the result summary, units and assumptions together.
- Use the visible experiment guides for thermal, flavour and decay questions, then save the inputs and results.
Controls and inputs
| Control | Meaning | Try this |
|---|---|---|
| Model to calculate | Selects the model supplying the main results, summary, permalink and exports. | Read the model name above the results after every change. |
| Mode-specific parameters | Only the controls relevant to the selected model are shown. | Open the mode guide rather than transferring another mode's phase or scale convention. |
| Experiment shortcuts | Jump to the additional cards available in that mode. | In the builder mode inspect thermal questions; in the neutrino mode inspect flavour and fixed-light-input questions. |
| Save, compare and permalink controls | Record the current input and its explicitly scoped result. | Save a reference before modifying one assumption. |
Reading the results
| Result | Meaning |
|---|---|
| Main result and live summary | Describe the selected model, inputs and supported conclusion. |
| Reference comparison | Names the measurement or calculation being compared and the assumptions needed to use it. |
| Experiments and diagnostics | Answer additional questions with separately labelled inputs, provenance and limitations. |
These modes answer different model questions and keep separate input records. The laboratory computes model responses and compares named references; it does not generate collider events. A missing matching external calculation remains pending rather than being borrowed from another input point.
Worked example
Choose the right starting point
- Choose the 5D builder mode to inspect a model already entered in SU(N) builder.
- Choose Higgs production for the isolated top-KK rate question.
- Choose Neutrino ring for neutral-fermion masses, mixing and decay questions.
- Follow the matching guide and begin with its reference example.
What to expect: The selected mode explains where each number comes from. Results from the three models are not silently combined.
Scope and limitations
- No mode constitutes a complete GHU fit to all available measurements.
- The thermal SU(3) benchmark is separate from the current SU(N) builder model and from the SU(7) mass certificates.
- Inputs supplied to calibrate or reconstruct a model are not subsequently predictions of those same observables.
If something is unclear
An expected experiment is missing.
Check the selected mode: thermal cards belong to the builder view, while flavour and fixed-light-input cards belong to the neutrino view.
A saved external result disappears after an input change.
Check its parameter match. A new input point requires a matching calculation or import.
