Electroweak axion in light of GRB221009A
Weikang Lin, Tsutomu T. Yanagida
Recently, arXiv:2210.05659 shows that a photon-axion like particle (ALP) oscillation can boost the survival rate of the high energy photons associated with the observed GRB221009A…
The anomalous shift of the weak boson mass and the quintessence electroweak axion
Weikang Lin, Tsutomu T. Yanagida, Norimi Yokozaki
One of the simplest ways to account for the observed W-boson mass shift is to introduce the triplet Higgs boson with zero hypercharge, whose vacuum expectation value is a…
Consistency of the string inspired electroweak axion with cosmic birefringence
Weikang Lin, Tsutomu T. Yanagida
We revisit the constraint from the recently reported cosmic birefringence on axion-like particles with a general decay constant. A particular attention is paid to the naturalness o…
Confronting the Galactic 511 keV emission with gauge boson dark matter
Weikang Lin, Tsutomu Yanagida
The gauge symmetry motivated from the successful generation of the seesaw mechanism and leptogenesis. We show that if the gauge boson constitutes a small fraction of th…
Dynamically Induced Topological Inflation
Gongjun Choi, Weikang Lin, Tsutomu T. Yanagida
We propose an inflation model in which the inflationary era is driven by the strong dynamics of gauge theory. The quark condensation in the confined phase of gauge…
Neutrino astronomy as a probe of physics beyond the Standard Model: decay of sub-MeV - gauge boson dark matter
Weikang Lin, Luca Visinelli, Donglian Xu +1
The symmetry, the essential component in the seesaw mechanism and leptogenesis, is naturally equipped with a massive gauge boson. If this gauge boson is the…
Discrete -symmetry, Various Energy Scales and Gravitational Waves
Gongjun Choi, Weikang Lin, Tsutomu T. Yanagida
We present a supersymmetric model where energy scales of a discrete -symmetry breaking () and cosmic inflation are commonly attributed to the confinement scale of a hidd…
Cosmic Birefringence and Electroweak Axion Dark Energy
Gongjun Choi, Weikang Lin, Luca Visinelli +1
Taking the recently reported non-zero rotation angle of the cosmic microwave background (CMB) linear polarization as the hint for a pseudo Nambu-Goldston…
