Magellan: Exploring the parameter space of the Type-II Two-Higgs-Doublet-Model

This page contains a collection of interactive dashboards, showcasing results from the MCMC scan of the 2HDM Type-II model. The information which is retained during the scan contain: theoretical properties such as the shape parameters of the potential, vacuum stability, or perturbativity; and also experimental relevant aspects such as production cross section and branching ratios.

Results

Interactive dashboards (bokeh/holoviews)

• Due to the large number of points, the results shown in the above interactive dashboards have been downsampled at random.
• Points can be selected by the 'Lasso Select' or 'Box Select' tools, and the selected points are also highlighted in the other projection windows.

Branching fractions and physical widths

• \( \mathcal{B}r (A \rightarrow XX) ~ \& ~ \Gamma_{A}/m_{A} \)
• \( \mathcal{B}r (H \rightarrow XX) ~ \& ~ \Gamma_{H}/m_{H} \)

LHC search projections

• \(A \rightarrow Zh\)

Datasets

• Diadem dataset (10.5281/zenodo.3228171)

MCMC setup and diagnostics

Interactive dashboards (bokeh/holoviews)

• Due to the large number of points, the results shown in the interactive dashboards have been downsampled at random. The visualisation contains 2000 points from the alignment, and also 2000 points from the wrong-sign regions.
• The points need to pass certain criteria, documented in the selection log

• LHC BSM searches

LHC search Projections

• \(H \rightarrow \tau\tau \)
• \(A \rightarrow \tau\tau \)
• \(H \rightarrow hh \rightarrow bbbb \)
