The new results as of January 2013 are run with the oscillation parameters of PDG 2012:
| Oscillation scenario | theta_12 (°) |
theta_13 (°) |
theta_23 (°) | delta | delta m^2_21 (eV^2) | delta m^2_31 (eV^2) |
| PDG 2012 | 33.58 | 9.12 | 40.40 | 0.0 | 7.58e-5 | 2.35e-3 |
Old stuff below. The information below is slightly obsolete, but is kept for the moment for those interested.
We have earlier run WimpAnn and WimpEvent with 7 differens oscillation parameter scenarios.
The different oscillation scenarios (A-G) are described below. If you don't want to gory details, scenario A is without oscillations and scenario B is the standard oscillation parameter scenario. All the other scenarios are versions with inverted hieararchy and/or non-zero theta_13. Hence, if you only want the best estimate of the oscillation effects, use scenario B.
Anyway, the oscillation scenarios have the following oscillation parameters (see [arXiv: 0709.3898] for the definition of the parameters).
| Oscillation scenario | theta_12 (°) |
theta_13 (°) |
theta_23 (°) | delta | delta m^2_21 (eV^2) | delta m^2_31 (eV^2) |
| A - no oscillations | 0.0 | 0.0 | 0.0 | 0.0 | 8.1e-5 * | 2.2e-3 * |
B - standard oscillations |
33.2 | 0.0 | 45.0 | 0.0 | 8.1e-5 | 2.2e-3 |
| C - inverted hieararchy | 33.2 | 0.0 | 45.0 | 0.0 | 8.1e-5 | -2.2e-3 |
| D - standard but with theta_13 = 10° | 33.2 | 10.0 | 45.0 | 0.0 | 8.1e-5 | 2.2e-3 |
| E - inverted hieararchy with theta_13 = 10° | 33.2 | 10.0 | 45.0 | 0.0 | 8.1e-5 | -2.2e-3 |
| F - standard but with theta_13 = 5° | 33.2 | 5.0 | 45.0 | 0.0 | 8.1e-5 | 2.2e-3 |
| G - inverted hieararchy with theta_13 = 5° | 33.2 | 5.0 | 45.0 | 0.0 | 8.1e-5 | -2.2e-3 |
*) Note that the mass squared differences have no meaning when all mixing angles are zero. We do need to enter some value though as that is needed for the formalism.
