Sensitivity of TeV scale new physics on electroweak metastability

We add new particles to the Standard Model at TeV scale, e.g., a gauge singlet scalar. Such new physics also provides a viable dark matter candidate. We have shown various phase diagrams and point out the regions of absolute stability, meta-stability and instability for the electroweak vacuum. We graphically demonstrate how the confidence level, at which stability of electroweak vacuum is excluded, depends on such new physics parameters.
