Constraining new physics from Higgs measurements with Lilith: update to LHC Run 2 results
View through CrossRef
Lilith is a public Python library for constraining new physics from
Higgs signal strength measurements. We here present version 2.0 of
Lilith together with an updated XML database which includes the current
ATLAS and CMS Run 2 Higgs results for
36 fb

Both the code and the database were extended from the ordinary Gaussian
approximation employed in Lilith-1.1 to using variable Gaussian and
Poisson likelihoods. Moreover, Lilith can now make use of correlation
matrices of arbitrary dimension. We provide detailed validations of the
implemented experimental results as well as a status of global fits for
reduced Higgs couplings, Two-Higgs-doublet models of Type I and Type II,
and invisible Higgs decays. Lilith-2.0 is available on GitHub and ready
to be used to constrain a wide class of new physics scenarios.
