Releases: DR-algo/DRalgo
DRalgo 1.2
Bug fixes:
Fixed a bug where Normalization4D would give an inconsistent result for non-abelian gauge groups
Fixed a bug where 2-loop tadpoles would fail to compute for models with many particles
Changes:
A new function "CalculatePotential[]" has been added with the exact same behavior as CalculatePotentialUS[]
Mode->0 now give results for re-summed couplings and 2-loop masses; both in the soft and ultra-soft theory
PrintScalarMass[] now prints the full result, with PrintScalarMass["LO"] etc working as before
->The same change has been made for PrintDebyeMass,PrintPressure, PrintScalarMassUS
An "AutoRG" option has been added (default set to True). When set to False beta-functions are not automatically added to the NLO contribution of PrintScalarMass.
Added a function BetaFunctions3DS[] which prints beta-functions in the soft theory.
DRalgo 1.1
DRalgo 1.1 update notes:
-Faster Soft->Supersoft reduction
-Added options for the effective potential
-Fixed bugs
Bug fixes:
-Fixed Yukawa beta-functions for Dirac Fermions
-Added fermion-mass corrections to Yukawa couplings
-Fixed an issue where sometimes erroneous information would be printed in the PrintCoupling[] command
-Fixed a bug with vector-like fermion beta functions
-Fixed bugs with some non-abelian contributions to the effective potential
Changes:
-The PrintTensorsVEV[] command (and similar for the other PrintTensor commands) behave slightly differently.
PrintTensorsVEV[] now gives the available tensors, and PrintTensorsVEV[X] (with X a number) returns the chosen tensor.
New Features:
-UseSoftTheory[] automatically loads the soft theory for calculating the effective potential
-UseUltraSoftTheory[] automatically loads the ultrasoft theory for calculating the effective potential
-Supplying the option "PerturbativeDiagonalization->True" to CalculatePotentialUS[] treats off-diagonal masses as perturbations
-PrintEffectivePotential[] now prints the full LO+NLO+NNLO effective potential; PrintEffectivePotential["LO"] etc works as before
-Supplying the "Normalization4D->True" command to ImportModelDRalgo[] gives effective coupling with 4d normalizations, that is, without extra factors of T, sqrt(T), etc in various couplings.
