Axion Emission from Proton Cooper Pairs in Neutron Stars
Koichi Hamaguchi, Natsumi Nagata, Jiaming Zheng
We investigate axion emission from singlet proton Cooper pairs in neutron stars, a process that dominates axion emission in young neutron stars in the KSVZ model. By re-deriving it…
Collapsing domain walls with -violating coupling to thermalized fermions and their impact on gravitational wave detections
Qing-Quan Zeng, Xi He, Zhao-Huan Yu +1
We study the dynamics of domain walls formed through the spontaneous breaking of an approximate symmetry in a scalar field, focusing on their collapse under the infl…
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…
Post-Inflationary Dark Matter Bremsstrahlung
Yann Mambrini, Keith A. Olive, Jiaming Zheng
Dark matter may only interact with the visible sector efficiently at energy scales above the inflaton mass, such as the Planck scale or the grand unification scale. In such a scena…
Capture of Electroweak Multiplet Dark Matter in Neutron Stars
Motoko Fujiwara, Koichi Hamaguchi, Natsumi Nagata +1
If dark matter has a sizable scattering cross section with nucleons, it can efficiently be captured by a neutron star. Its energy is then transferred to the neutron star as heat th…
Deeply Learned Preselection of Higgs Dijet Decays at Future Lepton Colliders
So Chigusa, Shu Li, Yuichiro Nakai +3
Future electron-positron colliders will play a leading role in the precision measurement of Higgs boson couplings which is one of the central interests in particle physics. Aiming…
