Gamma-ray Constraints on Decaying Dark Matter and Implications for IceCube
Timothy Cohen, Kohta Murase, Nicholas L. Rodd +2
Utilizing the Fermi measurement of the gamma-ray spectrum toward the Galactic Center, we derive some of the strongest constraints to date on the dark matter (DM) lifetime in the ma…
Don't be left in the dark: Improving LHC searches for dark photons using lepton-jet substructure
G. Barello, Spencer Chang, Christopher A. Newby +1
Collider signals of dark photons are an exciting probe for new gauge forces and are characterized by events with boosted lepton jets. Existing techniques are efficient in searching…
Consequences of R-Parity violating interactions for anomalies in and
N. G. Deshpande, Xiao-Gang He
We investigate the possibility of explaining the enhancement in semileptonic decays of , the anomalies induced by in $\bar B\to (K, K^*,…
The Inelastic Frontier: Discovering Dark Matter at High Recoil Energy
Joseph Bramante, Patrick J. Fox, Graham D. Kribs +1
There exist well motivated models of particle dark matter which predominantly scatter inelastically off nuclei in direct detection experiments. This inelastic transition causes the…
Nnaturalness
Nima Arkani-Hamed, Timothy Cohen, Raffaele Tito D'Agnolo +3
We present a new solution to the electroweak hierarchy problem. We introduce copies of the Standard Model with varying values of the Higgs mass parameter. This generically yiel…
Quark-Gluon tagging with Shower Deconstruction: Unearthing dark matter and Higgs couplings
Danilo Ferreira de Lima, Petar Petrov, Davison Soper +1
The separation of quark and gluon initiated jets can be an important way to improve the sensitivity in searches for new physics or in measurements of Higgs boson properties. We pre…
