An Update on the LHC Monojet Excess
Pouya Asadi, Matthew R. Buckley, Anthony DiFranzo +2
In previous work, we identified an anomalous number of events in the LHC jets+MET searches characterized by low jet multiplicity and low-to-moderate transverse energy variables. He…
Digging Deeper for New Physics in the LHC Data
Pouya Asadi, Matthew R. Buckley, Anthony DiFranzo +2
In this paper we describe a novel, model-independent technique of "rectangular aggregations" for mining the LHC data for hints of new physics. A typical (CMS) search now has hundre…
Collapsed Dark Matter Structures
Matthew R. Buckley, Anthony DiFranzo
The distributions of dark matter and baryons in the Universe are known to be very different: the dark matter resides in extended halos, while a significant fraction of the baryons…
Multi-component Dark Matter through a Radiative Higgs Portal
Anthony DiFranzo, Gopolang Mohlabeng
We study a multi-component dark matter model where interactions with the Standard Model are primarily via the Higgs boson. The model contains vector-like fermions charged under $SU…
Vector Dark Matter through a Radiative Higgs Portal
Anthony DiFranzo, Patrick J. Fox, Tim M. P. Tait
We study a model of spin-1 dark matter which interacts with the Standard Model predominantly via exchange of Higgs bosons. We propose an alternative UV completion to the usual Vect…
Dark Matter Benchmark Models for Early LHC Run-2 Searches: Report of the ATLAS/CMS Dark Matter Forum
Daniel Abercrombie, Nural Akchurin, Ece Akilli +136
This document is the final report of the ATLAS-CMS Dark Matter Forum, a forum organized by the ATLAS and CMS collaborations with the participation of experts on theories of Dark Ma…
Searching for MeV-Scale Gauge Bosons with IceCube
Anthony DiFranzo, Dan Hooper
Light gauge bosons can lead to resonant interactions between high-energy astrophysical neutrinos and the cosmic neutrino background. We study this possibility in detail, considerin…
A 3.55 keV Line from Exciting Dark Matter without a Hidden Sector
Asher Berlin, Anthony DiFranzo, Dan Hooper
Models in which dark matter particles can scatter into a slightly heavier state which promptly decays to the lighter state and a photon (known as eXciting Dark Matter, or XDM) have…
Hidden On-Shell Mediators for the Galactic Center Gamma-Ray Excess
Mohammad Abdullah, Anthony DiFranzo, Arvind Rajaraman +3
We present simplified models for the galactic center gamma-ray excess where Dirac dark matter annihilates into pairs or triplets of on-shell bosonic mediators to the Standard Model…
Systematically Searching for New Resonances at the Energy Frontier using Topological Models
Mohammad Abdullah, Eric Albin, Anthony DiFranzo +8
We propose a new strategy to systematically search for new physics processes in particle collisions at the energy frontier. An examination of all possible topologies which give ide…
Mono-Higgs: a new collider probe of dark matter
Linda M. Carpenter, Anthony DiFranzo, Michael Mulhearn +3
We explore the LHC phenomenology of dark matter (DM) pair production in association with a 125 GeV Higgs boson. This signature, dubbed `mono-Higgs,' appears as a single Higgs boson…
Simplified Models for Dark Matter Interacting with Quarks
Anthony DiFranzo, Keiko I. Nagao, Arvind Rajaraman +1
We investigate simplified models in which dark matter particles, taken to be either Dirac or Majorana fermions, couple to quarks via colored mediators. We determine bounds from col…
