Power Corrections to the Universal Heavy WIMP-Nucleon Cross Section
Chien-Yi Chen, Richard J. Hill, Mikhail P. Solon +1
WIMP-nucleon scattering is analyzed at order in Heavy WIMP Effective Theory. The power corrections, where is the WIMP mass, distinguish between different und…
Higgs Boson Decays to Dark Photons through the Vectorized Lepton Portal
Qianshu Lu, David E. Morrissey, Alexander M. Wijangco
Vector-like fermions charged under both the Standard Model and a new dark gauge group arise in many theories of new physics. If these fermions include an electroweak doublet and si…
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…
Dark Matter in the Coming Decade: Complementary Paths to Discovery and Beyond
Sebastian Arrenberg, Howard Baer, Vernon Barger +29
In this Report we discuss the four complementary searches for the identity of dark matter: direct detection experiments that look for dark matter interacting in the lab, indirect d…
Large θ_13 in a SUSY SU(5)xT' Model
Mu-Chun Chen, Jinrui Huang, K. T. Mahanthappa +1
In the model based on SUSY SU(5) combined with the T' family symmetry, it is shown in Phys. Lett. B 652, 34 (2007) and Phys. Lett. B 681, 444 (2009) that fermion mass hierarchy and…
Particle Physics Implications and Constraints on Dark Matter Interpretations of the CDMS Signal
Randel C. Cotta, Arvind Rajaraman, Tim M. P. Tait +1
Recently the CDMS collaboration has reported an excess of events in the signal region of a search for dark matter scattering with Silicon nuclei. Three events on an expected backgr…
Dark Matter in the Coming Decade: Complementary Paths to Discovery and Beyond
Daniel Bauer, James Buckley, Matthew Cahill-Rowley +16
In this report we summarize the many dark matter searches currently being pursued through four complementary approaches: direct detection, indirect detection, collider experiments,…
Effective Theories of Gamma-ray Lines from Dark Matter Annihilation
Arvind Rajaraman, Tim M. P. Tait, Alexander M. Wijangco
We explore theories of dark matter in which dark matter annihilations produce mono-energetic gamma rays ("lines") in the context of effective field theory, which captures the physi…
Compatibility of theta13 and the Type I Seesaw Model with A4 Symmetry
Mu-Chun Chen, Jinrui Huang, Jon-Michael O'Bryan +2
We derive formulae for neutrino masses and mixing angles in a type I seesaw framework with an underlying A4 flavor symmetry. In particular, the Majorana neutrino mass matrix includ…
LHC Bounds on Interactions of Dark Matter
Arvind Rajaraman, William Shepherd, Tim M. P. Tait +1
We derive limits on the interactions of dark matter with quarks from ATLAS null searches for jets + missing energy based on ~1 fb^-1 of integrated luminosity, using a model-insensi…
