Sterile Neutrinos and Flavor Ratios in IceCube
Vedran Brdar, Joachim Kopp, Xiao-Ping Wang
The flavor composition of astrophysical neutrinos observed in neutrino telescopes is a powerful discriminator between different astrophysical neutrino production mechanisms and can…
Impeded Dark Matter
Joachim Kopp, Jia Liu, Tracy R. Slatyer +2
We consider dark matter models in which the mass splitting between the dark matter particles and their annihilation products is tiny. Compared to the previously proposed Forbidden…
Hunting for Dark Matter Coannihilation by Mixing Dijet Resonances and Missing Transverse Energy
Malte Buschmann, Sonia El Hedri, Anna Kaminska +5
Simplified models of the dark matter (co)annihilation mechanism predict striking new collider signatures untested by current searches. These models, which were codified in the coan…
New Signatures of Flavor Violating Higgs Couplings
Malte Buschmann, Joachim Kopp, Jia Liu +1
We explore several novel LHC signatures arising from quark or lepton flavor violating couplings in the Higgs sector, and we constrain such couplings using LHC data. Since the large…
