Non-Minimal Dark Sectors: Mediator-Induced Decay Chains and Multi-Jet Collider Signatures
Keith R. Dienes, Doojin Kim, Huayang Song +3
A preponderance of astrophysical and cosmological evidence indicates that the universe contains not only visible matter but also dark matter. In order to suppress the couplings bet…
Neutrino Topology Reconstruction at DUNE and Applications to Searches for Dark Matter Annihilation in the Sun
Carsten Rott, DongYoung Jeong, Jason Kumar +1
We consider a new technique for neutrino energy and topology reconstruction at DUNE. In particular, we show that when the direction of the incoming neutrino is known, one can use t…
New Dark Matter Search Strategies at DUNE
Carsten Rott, Seongjin In, Jason Kumar +1
If dark matter annihilates to light quarks in the core of the Sun, then a flux of 236 MeV neutrinos will be produced from the decay of stopped kaons. We consider strategies for DUN…
Off-Diagonal Dark-Matter Phenomenology: Exploring Enhanced Complementarity Relations in Non-Minimal Dark Sectors
Keith R. Dienes, Jason Kumar, Brooks Thomas +1
In most multi-component dark-matter scenarios, two classes of processes generically contribute to event rates at experiments capable of probing the nature of the dark sector. The f…
Directional Searches at DUNE for Sub-GeV Monoenergetic Neutrinos Arising from Dark Matter Annihilation in the Sun
Carsten Rott, Seongjin In, Jason Kumar +1
We consider the use of directionality in the search for monoenergetic sub-GeV neutrinos arising from the decay of stopped kaons, which can be produced by dark matter annihilation i…
Dark Matter Searches for Monoenergetic Neutrinos Arising from Stopped Meson Decay in the Sun
Carsten Rott, Seongjin In, Jason Kumar +1
Dark matter can be gravitationally captured by the Sun after scattering off solar nuclei. Annihilations of the dark matter trapped and accumulated in the centre of the Sun could re…
Vector dark matter at the LHC
Jason Kumar, Danny Marfatia, David Yaylali
We consider monojet searches at the Large Hadron Collider (LHC) for spin-1 dark matter that interacts with quarks through a contact operator. If the dark matter particles are produ…
A New Direction in Dark-Matter Complementarity: Dark-Matter Decay as a Complementary Probe of Multi-Component Dark Sectors
Keith R. Dienes, Jason Kumar, Brooks Thomas +1
In single-component theories of dark matter, the amplitudes for dark-matter production, annihilation, and scattering can be related to each other through various crossing…
Overcoming Velocity Suppression in Dark-Matter Direct-Detection Experiments
Keith R. Dienes, Jason Kumar, Brooks Thomas +1
Pseudoscalar couplings between Standard-Model quarks and dark matter are normally not considered relevant for dark-matter direct-detection experiments because they lead to velocity…
Spin Determination for Fermiophobic Bosons
Jason Kumar, Arvind Rajaraman, David Yaylali
We discuss the prospects for production and detection of fermiophobic bosons (exotic bosons decaying only to standard model gauge bosons) at the LHC, and describe simple methods fo…
Collider Searches for Fermiophobic Gauge Bosons
Joseph Bramante, R. S. Hundi, Jason Kumar +2
We explore the phenomenology of an extra U(1) gauge boson which primarily couples to standard model gauge bosons. We classify all possible parity-odd couplings up to dimension 6 op…
