Simulator: 5D builder predictions
Convert the supported SU(N) builder vacuum into dimensionful masses and compare specified model quantities with named reference measurements.
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 after the builder's potential and spectrum have been understood. It translates the dimensionless model into quantities that can be compared with measurements, while retaining the assumptions behind each comparison. The result is a theoretical calculation, not simulated collider data.
First steps
- Load or construct the model in SU(N) builder.
- Select the builder mode in Simulator and choose the located minimum or a manual phase probe.
- Read the coupling choice and the W-mass anchor before interpreting GeV values.
- Inspect the prediction table, fermion masses and tower plots together.
Controls and inputs
| Control | Meaning | Try this |
|---|---|---|
| At the minimum / probe | Chooses the located vacuum or an explicitly selected phase. | Compare the two labels before attributing a mass to the vacuum. |
| g₄ and the g₂(1/R) option | Choose the coupling convention used in the Higgs-curvature conversion. | Move g₄ while retaining the same phase and observe which outputs change. |
| 3D tower view | Displays calculated masses alongside reference lines and the explicitly conditional colour-sector bound. | Rotate the landscape and confirm values in the table. |
Reading the results
| Result | Meaning |
|---|---|
| Compactification and Higgs scales | Use the model's own phase normalization and measured-W calibration. |
| Weak-angle and fermion comparisons | Compare the supported embedding and Wilson-line mass structure with the named reference quantities. |
| KK mass axis | Shows predicted states and the stated reference reach; the coloron comparison assumes the relevant colour sector lives in the bulk. |
The measured W mass supplies the scale calibration. In this mode, changing g₄ at a fixed builder vacuum changes the displayed Higgs mass, while the anchored KK masses do not follow that slider. A manually selected probe is not a dynamically selected vacuum.
Worked example
See what fixes the mass scale
- Load a builder reference with an available broken vacuum.
- Record the Higgs mass and one KK level in Simulator.
- Change only g₄.
- Compare the changed Higgs result with the W-anchored tower masses.
What to expect: The controls affect different parts of the conversion. A stationary tower under this slider is an expected feature of the chosen calibration.
Scope and limitations
- A symmetric vacuum does not provide the nonzero phase needed for this electroweak scale calibration.
- A probe point is not a vacuum certificate.
- Colour-sector limits require their stated particle and localization assumptions; the display is not a complete experimental fit.
If something is unclear
The compactification scale is undefined.
Check whether the selected vacuum is symmetric or unresolved before changing the coupling.
Changing g₄ leaves the tower unchanged.
Read the W-mass calibration and the Higgs-specific role of g₄ in this mode.
