New Fixed-Target Experiments to Search for Dark Gauge Forces
James D. Bjorken, Rouven Essig, Philip Schuster +1
Fixed-target experiments are ideally suited for discovering new MeV-GeV mass U(1) gauge bosons through their kinetic mixing with the photon. In this paper, we identify the producti…
Probing Dark Forces and Light Hidden Sectors at Low-Energy e+e- Colliders
Rouven Essig, Philip Schuster, Natalia Toro
A dark sector -- a new non-Abelian gauge group Higgsed or confined near the GeV scale -- can be spectacularly probed in low-energy e+e- collisions. A low-mass dark sector can expla…
Bounds on Cross-sections and Lifetimes for Dark Matter Annihilation and Decay into Charged Leptons from Gamma-ray Observations of Dwarf Galaxies
Rouven Essig, Neelima Sehgal, Louis E. Strigari
We provide conservative bounds on the dark matter cross-section and lifetime from final state radiation produced by annihilation or decay into charged leptons, either directly or v…
Direct Detection of Non-Chiral Dark Matter
Rouven Essig
Direct detection experiments rule out fermion dark matter that is a chiral representation of the electroweak gauge group. Non-chiral real, complex and singlet representations, howe…
The Minimally Tuned Minimal Supersymmetric Standard Model
Rouven Essig, Jean-François Fortin
The regions in the Minimal Supersymmetric Standard Model with the minimal amount of fine-tuning of electroweak symmetry breaking are presented for general messenger scale. No a pri…
Implications of the LEP Higgs Bounds for the MSSM Stop Sector
Rouven Essig
The implications of the LEP Higgs bounds on the MSSM stop masses and mixing are compared in two different regions of the Higgs parameter space. The first region is the Higgs decoup…
