Higgs Descendants
Clifford Cheung, Yasunori Nomura
We define a Higgs descendant to be a particle beyond the standard model whose mass arises predominantly from the vacuum expectation value of the Higgs boson. Higgs descendants…
Simplified Models for LHC New Physics Searches
Daniele Alves, Nima Arkani-Hamed, Sanjay Arora +92
This document proposes a collection of simplified models relevant to the design of new-physics searches at the LHC and the characterization of their results. Both ATLAS and CMS hav…
Supergravity Computations without Gravity Complications
Clifford Cheung, Francesco D'Eramo, Jesse Thaler
The conformal compensator formalism is a convenient and versatile representation of supergravity (SUGRA) obtained by gauge fixing conformal SUGRA. Unfortunately, practical calculat…
Affleck-Dine Cogenesis
Clifford Cheung, Kathryn M. Zurek
We propose a novel framework in which the observed baryon and dark matter abundances are simultaneously generated via the Affleck-Dine mechanism. In its simplest realization, Affle…
The Cosmological Axino Problem
Clifford Cheung, Gilly Elor, Lawrence J. Hall
We revisit the cosmology of the supersymmetric QCD axion, highlighting the existence of a serious cosmological axino problem that is fully analogous to the gravitino problem of ove…
The Spectrum of Goldstini and Modulini
Clifford Cheung, Francesco D'Eramo, Jesse Thaler
When supersymmetry is broken in multiple sectors via independent dynamics, the theory furnishes a corresponding multiplicity of "goldstini" degrees of freedom which may play a subs…
