# WimpSim Oscillation Scenarios

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 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.
