  • 30.01.2009, CD -ModelDatabase:
  • 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:
      • 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.
