ScannerS is a C++ tool for scanning the parameter space of arbitrary scalar extensions of the Standard Model (SM), which is designed for an easy implementation of experimental results/bounds by the user. The code also contains various example implementations such as the Two Higgs Doublet Model (2HDM), a complex singlet extension with or without dark matter (xSM), and the Next to Minimal Two Higgs Doublet Model (N2HDM), which is an extension of the THDM by a real scalar singlet -- See also References.

The code provides a convenient way to perform parameter space scans while applying phenomenological bounds using various interfaces to codes such as HiggsBounds/Signals, Superiso, SusHi, Hdecay and MicrOmegas.

Currently the code contains several core routines to numerically generate (on each scanning step) a local minimum (vacuum) from an arbitrary scalar potential expression. The potential and various options are specified by the user in a Mathematica notebook. The notebook generates an input file which is used in the main C++ code where the scanning analysis is specified. The core code contains routines to: test tree level unitarity; detect symmetries for the mixing matrix; detect flat directions and degenerate states; and various template functions to test the stability of the potential as well as to impose constraints (see comments in the code and the manual for more information).
