Does the new version supersede the previous version?: Yes

Nature of problem:
Calculation of neutrino masses and the neutrino mixing matrix at one-loop level in the R-parity violating minimal supersymmetric standard model. The solution to the renormalisation group equations must be consistent with a high or weak-scale boundary condition on supersymmetry breaking parameters and R-parity violating parameters, as well as a weak-scale boundary condition on gauge couplings, Yukawa couplings and the Higgs potential parameters.

Solution method:
Nested iterative algorithm.

Reasons for new version:
Added functionality (computation of all three neutrino masses and their mixings) and bug-fixes.

Summary of revisions:
  • Additional error flags for which particle has become tachyonic.
  • Allowing tanb(MX) boundary condition. New SOFTSUSY Block 7 allows the user to change the number of loops in calculating Higgs mass and electroweak symmetry breaking calculation to be 1 or 2.
  • mGMSB fine tuning fixed: thanks to Matthias Hamer for pointing out the bug.
  • RPV SUSY couplings now able to be set at MZ as well as at SUSY breaking scale.
  • Default output format from softpoint.x is SLHA
  • Fixed third-family mixing contribution to gluino mass. MIXING=-1 now banned.
  • Small bug-fix in charged Higgs loop calculation, in gaugino contribution. Now respects Z2 (U1R-PQ) flip exactly due to bug-fixes in gluino mass.
  • Gravitino default mass changed to Planck scale.
  • Added 1-loop RPV loop corrections to neutrino masses - allows computation of neutrino oxcillation parameters.

Restrictions:
SOFTSUSY will provide a solution only in the perturbative régime and it assumes that all couplings of the MSSM are real (i.e. CP-conserving).

Running time:
A second per parameter point.
