Himalaya-2.0.1

Changes

• The estimate of the non-logarithmic contributions to the quartic
  Higgs coupling λ due to the hierarchy expansion has been changed:
  Xt^5 and Xt^6 terms are no longer taken into account in the
  uncertainty estimate, because they do not appear at 3-loop
  O(αt*αs^2). Only the Xt^4 term is used in the uncertainty
  estimate, if it is absent from the selected hierarchy. As a
  result, the uncertainty estimate is now symmetric in Xt.

Himalaya-2.0.0

New features

• The 3-loop O(αt*αs^2) contribution to the CP-even Higgs mass matrix
  in the MSSM is now calulated in the DR'-bar scheme by default.
  Shifts to the MDR'-bar and H3m schemes are provided separately.

• The 3-loop O(αt*αs^2) contribution to quartic Higgs coupling λ of
  the Standard Model is calculated in the DR'-bar scheme. A shift to
  the MS-bar scheme is provided separately.

• A Mathematica interface for Himalaya has been added. See README.md
  for a usage example.

Changes

• The default renormalization scheme for the input parameters has
  been changed to DR'-bar.

• The names of the following member functions of the
  HierarchyObject class have been changed:

  • getExpUncertainty() -> getDMhExpUncertainty()
  • getDRToMDRShift() -> getDMhDRbarPrimeToMDRbarPrimeShift()

v1.0.1

Changes in the example output and documentation. Add a new member function to the HierarchyObject:

  getH3mHierarchyNotation(int hierarchy)

With this function one gets the Himalaya hierarchy key mapped to the notation of H3m.
