This is a list of changes to hpair.f since October 1998:
May 8 2017: Reading in of Z decay width corrected.
(thanks to M. Muehlleitner)
June 19 2015: Bug corrected for consistent calculation of LO cxn
(thanks to R. Gr"ober)
June 12 2015: Version 2.00: Major upgrade
- Inclusion of dim6 operators up to NLO according to
R.~Grober, M.~Muhlleitner, M.~Spira and J.~Streicher,
%``NLO QCD Corrections to Higgs Pair Production including Dimension-6
%Operators,''
arXiv:1504.06577 [hep-ph].
with the according extension of the input file (see the
comments at the beginning of the fortran file for
explanations).
- link to LHAPDF implemented
- alpha_s defined via alpha_s(M_Z) now instead of Lambda_5
March 12 2012: - Modification of complex functions to today's fortran
standards
September 12 2007: - Link to MRST2001 PDFs corrected due to errorneous
interchange of u and d. (thanks to M. Ciccolini)
April 12 2005: - Link to CTEQ6 and MRST2001 PDFs
(NGROUP = -1: CTEQ6 -2: MRST2001)
July 18 2001 : - Addition of the cut EPSILON to input file for
controlling instabilities at very large energies
(thanks to Tao Han).
January 13 1999 : - Improvement of the whole function RUNM including a
change in the input strange mass (MSbar mass at Q=1 GeV)
