This is the changelog of the Lilith library.
For the changelog of the database of experimental results, see data/changelog
** Feb. 14, 2015: v1.1, first official release
** Mar. 10, 2015: v1.1.1, correction of a minor bug in the Lilith C API
(the Python Lilith library was not found depending on
the location of the main source file)
** Apr. 14, 2015: v1.1.2, list of possible final states and reduced couplings
supplemented by muon-muon
** Aug. 11, 2015: v1.1.3
* File containing the bibtex references to the latest experimental
results added; data/latest-references.txt
* Common coupling "ll" grouping both "mumu" and "tautau" added
* Correction of a bug in the reduced coupling mode that made the
the use of the "ZH" and "WH" couplings not possible
* Correction of a bug that made the code exit in the case that both
the "LO" and "BEST-QCD" precisions were used in a single run in the
reduced couplings mode, thanks to Sushruth Malaridharan
** May, 2017: v1.1.4
* Internal modifications for the interface to micrOMEGAs 4.3.1
(Lilith≥1.1.4 can be directly used in micrOMEGAs≥4.3.1, see arXiv:1606.03834)
* 2HDM fit routine added in examples/python
* 13 TeV results supported (form factors, cross sections grids implemented)
** June, 2019: v2.0 by Sabine Kraml, Tran Quang Loc, Dao Thi Nhung and Le Duc Ninh
code:
* extended likelihood calculation by variable Gaussian and generalized Poisson dist.
* added use of N-dim correlation matrices (for Gaussian or variable Gaussian approx.)
* added tH production mode and top = ttH+tH category
* added gg -> VH for VH production mode
* added bbH production mode (but no experimental data available so far)
* added tHq_tHW_ttH and WH_qqZH_ggZH_VBF xsection grids
* corrected a minor bug (prod == prod + "13") in computelikelihood.py
* corrected a bug in writeresults() with XML format (case dim = 2)
* fixed a minor bug in writeresults() with SLHA format
* updated and improved python code examples
database:
* updated database to 36fb-1 Run 2 results, see data/changelog.txt
** Aug, 2020: code converted to Python 3 by Marius Bertrand (still version 2.0)
** Dec, 2020: added Variable Gaussian 1, added abs() to the denominator of Variable Gaussian 2 to force LogL negative
(this is to avoid numerical issue with sqrt() of the denominator)
