Vortex Creep Heating vs. Dark Matter Heating in Neutron Stars
Motoko Fujiwara, Koichi Hamaguchi, Natsumi Nagata +1
Dark matter particles captured in neutron stars deposit their energy as heat. This DM heating effect can be observed only if it dominates over other internal heating effects in NSs…
Vortex Creep Heating in Neutron Stars
Motoko Fujiwara, Koichi Hamaguchi, Natsumi Nagata +1
Recent observations of old warm neutron stars suggest the presence of a heating source in these stars, requiring a paradigm beyond the standard neutron-star cooling theory. In this…
Electroweak Loop Contributions to the Direct Detection of Wino Dark Matter
John Ellis, Natsumi Nagata, Keith A. Olive +1
Electroweak loop corrections to the matrix elements for the spin-independent scattering of cold dark matter particles on nuclei are generally small, typically below the uncertainty…
Thermal Leptogenesis in the Minimal Gauged Model
Alessandro Granelli, Koichi Hamaguchi, Natsumi Nagata +2
We discuss the thermal leptogenesis mechanism within the minimal gauged U(1) model to explain the observed baryon asymmetry of the Universe (BAU). In such framework, th…
Quantifying Limits on CP Violating Phases from EDMs in Supersymmetry
Kunio Kaneta, Natsumi Nagata, Keith A. Olive +2
We revisit the calculation of the electron, neutron, and proton electric dipole moments (EDMs) in the constrained minimal supersymmetric standard model (CMSSM). The relatively larg…
