Mono-X Versus Direct Searches: Simplified Models for Dark Matter at the LHC
Seng Pei Liew, Michele Papucci, Alessandro Vichi +1
We consider simplified models for dark matter (DM) at the LHC, focused on mono-Higgs, -Z, or -b produced in the final state. Our primary purpose is to study the LHC reach of a rela…
Simplified Models for Dark Matter and Missing Energy Searches at the LHC
Jalal Abdallah, Adi Ashkenazi, Antonio Boveia +22
The study of collision events with missing energy as searches for the dark matter (DM) component of the Universe are an essential part of the extensive program looking for new phys…
Monojet versus rest of the world I: t-channel Models
Michele Papucci, Alessandro Vichi, Kathryn M. Zurek
Monojet searches using Effective Field Theory (EFT) operators are usually interpreted as a robust and model independent constraint on direct detection (DD) scattering cross-section…
On the production of a composite Higgs boson
Ian Low, Alessandro Vichi
We present a prescription for computing the gluon fusion production rate of a composite Higgs boson, which arises as a pseudo-Nambu-Goldstone boson, using effective lagrangians. Th…
T-parity, its problems and their solution
Duccio Pappadopulo, Alessandro Vichi
We point out a basic difficulty in the construction of little-Higgs models with T-parity which is overlooked by large part of the present literature. Almost all models proposed so…
Theoretical Constraints on the Higgs Effective Couplings
Ian Low, Riccardo Rattazzi, Alessandro Vichi
We derive constraints on the sign of couplings in an effective Higgs Lagrangian using prime principles such as the naturalness principle, global symmetries, and unitarity. Specific…
