Collider Search: Higgs and SUSY
- Simone Pagan Griso (Lawrence Berkeley National Lab. (US))
A search for compressed supersymmetry in the stau-neutralino ($\tilde{\tau}\tilde{\chi}^{0}_{1}$) coannihilation region is presented. The search targets final states with exactly one low-energy (``soft'') hadronically-decaying $\tau$ lepton and large missing transverse momentum ($\vec{E}^{miss}_{T}$) due to the natural kinematic boost from a high transverse momentum jet from initial state...
We show that a simple Higgs-portal dark matter model can contain stable non-topological soliton states of dark matter. This macroscopic dark matter candidate has its interior in an electroweak symmetry unbroken vacuum. These dark matter balls can have its radius around the atomic scale and mass as large as $10^{34}$ GeV. We discuss the formation of these dark matter balls from the first-order...
