• 30.01.2009, CD -ModelDatabase:
  • Updated all models to be compliant with the change PauliMatrix -> PauliSigma made in V1.2.5.
• 27.01.2009, CD -V1.2.5:
  • Made FR compatible with Mathematica 7.0. The FR function PauliMatrix is now called PauliSigma.
  • Changed the routine TreatMajoranasAndCC in Intialisation.m.<br />It is now more efficient, and a bug was corrected along the way, which affected fermion chains with two identical fermions, one of them being charge conjugated.
• 13.01.2009, CD -V1.2.4:
  • Added LQCD to the model file FirstExample.fr.
  • Small bug fix for the TraditionalForm and the StandardForm of dSUN. Only the printing was affected.
• 16.10.2008, CD -V1.2.3:
  • Fixed bug in the running of the strong coupling of the MadGraph interface. The running is now done correctly.
• 29.08.2008, CD -V1.2.2:
  • Fixed bug in the internal index renaming. Internal indices are now renamed indepently at each call of FeynmanRules. (Thanks to R. Frederix)
• 15.08.2008, NC -V1.2.1:
  • Fixed CH interface bug where very small external parameters were not being written to file correctly.
  • Fixed CH interface bug where arccos was not being written to file correctly.
  • Fixed Core bug where spin 2 particles were not being read in correctly.
• 25.06.2008, Finished new manual ​arXiv:0806:4194. Please cite! :)
• 25.06.2008, CD - V1.2.0:
  • Compatibility issue with Mathematica 6.0 resolved (Thanks to Benjamin Fuks).
  • Template interface:
    • Wrote new Template interface that can be modified for a new interface to a monte carlo package.
  • FeynArts interface:
    • Now reclasses particles if necessary (when the lagrangian contains terms specific to members).
    • Now defines new coupling constants for each vertex which can simplify the vertices considerably.
    • Parameters written to FeynArts model files as:
      • M$FACouplings
      • M$ExtParams
      • M$IntParams
      • M$Masses
      • M$Widths
    • Compatibility issues with FormCalc resolved. (Thanks to Benjamin Fuks)
    • Bug fix for ghosts.
    • Bug fix for default classes.
    • Fermion flow is now treated consistently.
    • IndexSum[ ] function is now treated consistently.
  • !CalcHEP/CompHEP interface:
    • Added functions !WriteCHParameters and !ReadCHParameters for sharing parameters.
    • Fixed bug when multiple particles have the same name.
  • MadGraph interface:
    • Added the decomposition of the four-gluon vertex into a three-point vertices including an auxiliary tensor particle.
    • Added the five-dimensional operators describing the coupling of a (pseudo-)scalarto vectors in the large top-mass limit.
    • Various bug fixes.
  • Core code:
    • Improved flavor expansion routine.
    • Added several options to FeynmanRules:
      • Free
      • Contains
    • Vertices renamed to SelectVertices and most FeynmanRules options added.
    • MergeVertexLists renamed to MergeVertices.
    • Majorana and charge conjugated Fermions implemented.
    • Fermion flow is now treated consistently.
    • LoadMergedModel is merged with LoadModel.
    • Extended the number of derivatives of fields that could be taken to infinity.
    • Added functions WriteParameters and ReadParameters for sharing parameters.
    • Added new checks for the lagrangian such as:
      • CheckHermiticity
      • CheckMassSpectrum
      • CheckKineticTermNormalisation
    • Common format for interfaces.
    • The output of FeynmanRules is now the list of vertices.
    • Various bug fixes.
  • 3-Site Model implementation:
    • Fixed bug that affected the kinetic terms.
    • Fixed ghost lagrangian terms.

• 08.05.2008, CD - V1.0.4:
  • Bug fix in the CalcHep interface.
  • Bug fix in the FeynArts interface: Sign corrected in the SSV vertex, as well as typo corrected in VVVV vertex.
• 25.04.2008, CD - V1.0.3:
  • Better treatment of the del[ ] function. An arbitrary number of derivatives is now supported. (Thanks to C. Arnesen for pointing this out)
• 15.04.2008, CD - V1.0.2:
  • Bug fix in the MG interface.
• 01.04.2008, CD - Typo corrected in HiggsEffective.fr (M$Information had an unclosed paranthesis). <br />New version uploaded.
• 17.03.2008, CD - V1.0.1:
  • Bug fix in the FeynArts interface: typo corrected in the interface for the ghosts.
  • Bug fix in the MadGraph interface: If two or more particles have the same mass, the mass symbols need to be renamed (MadGraph only allows each symbol to be defined once)
• 08.03.2008, CD - V1.0 uploaded.
• 22.02.2008, CD - Uploading the packages.
• 10.02.2008, CD - First try to get the web page running.
