In this talk, I will review the importance of "Gauge invariance" in the search for Dark matter at the High Energy Collider including LHC.
The major topics I will include will be
1) The limit of effective field theory / simplified model approach at the High Energy collider
2) Dark matter showering at the High Energy collider
We explore the parameter space of the phenomenological Minimal Supersymmetric Standard Model (pMSSM) with a light neutralino thermal dark matter (M ̃χ01 ≤ Mh/2) that is consistent with current collider and astrophysical constraints. We identify that a narrow region with light Higgsinos having masses between 125-160 GeV survives the present constraints for the μ < 0 scenario, including the...
Dark matter bound states may exist within the dark sector, characterized by a substantial dark force. Depending on the spins and parity properties of the force carriers, Standard Model particles may primarily couple with either the lowest or excited bound states. We discuss the associated collider signatures at the LHC for various simplified models.
