Table 4.
Constraints on Δα/α in the Baseline and Null scenarios for the Unification, Dilaton, and Clocks models, as reported in Paper 1 (Clara & Martins 2020) and Paper 2 (Martins 2021).
| Scenarios | Unification | Dilaton | Clocks |
|---|---|---|---|
| Paper 1 (Baseline) | 12.5 ± 2.9 | 19.9 ± 4.5 |  |
| Paper 1 (Null) | 4.6 ± 3.8 | 5.8 ± 6.5 |  |
| Paper 2 (Baseline) | 16.1 ± 3.9 | 22.6 ± 5.5 |  |
| Paper 2 (Null) | 4.6 ± 5.5 | 3.7 ± 8.4 |  |
Notes. The listed values are in ppm and correspond to the best fit in each case and to the range of values within Δχ2 = 4 of it. The fiducial model used in these papers is not the same as we used here, and the full parameter space was different in the two papers.
