WISPedia -- the WISPs Encyclopedia
Conrado Albertus, Francesca Chadha-Day, Arturo de Giorgi +8
The Weakly-Interacting Slim Particle encyclopedia (WISPedia) is a comprehensive reference work dedicated to the systematic compilation of theoretical models, Effective Field Theori…
Beyond thresholds: reconstructing UV physics from IR expansions
Hiromasa Takaura, Wen Yin
We show that ultraviolet information can be extracted from low-energy expansion coefficients, assuming analyticity and the absence of massless singularities. By reorganizing the lo…
Hubble-Scale Tachyonic Shocks from Low-Scale Inflation -- A New Gravitational-Wave Window on Inflation
Haruto Masubuchi, Yuma Narita, Wen Yin
Current bounds on the tensor-to-scalar ratio imply that the energy scale of inflation may lie below the grand-unified scale. In this paper, we show that in a broad class of single-…
Axion Cosmology with Multi-Branch Yang-Mills
Tsubasa Sugeno, Wen Yin
It is known that Yang-Mills theories, especially in the large- limit, exhibit a -vacuum structure with a multi-branched vacuum energy. In this work, we demonstrate that this…
Revisiting axion dark matter with nonlinear transitions
Max Miyazaki, Yuma Narita, Deheng Song +2
Recently, two of the present authors showed that even when the axion momentum is much smaller than its mass, the axion can still behave like radiation if its energy density greatly…
Relativistic Axion with Nonrelativistic Momenta: A Robust Bound on Minimal ALP Dark Matter
Yuma Narita, Wen Yin
The axion-like particle (ALP), a pseudo Nambu-Goldstone boson that couples to two photons, has been studied extensively in recent years as a dark matter candidate. For initial fiel…
Superheavy dark matter from the natural inflation in light of the highest-energy astroparticle events
Kohta Murase, Yuma Narita, Wen Yin
Superheavy dark matter has been attractive as a candidate of particle dark matter. We propose a ``natural" particle model, in which the dark matter serves as the inflaton in natura…
Explaining the KM3-230213A Detection without Gamma-Ray Emission: Cosmic-Ray Dark Radiation
Yuma Narita, Wen Yin
Recently, a high-energy neutrino event, designated KM3-230213A, was observed by the KM3NeT/ARCA detector in the Mediterranean Sea. This event is characterized by a reconstructed mu…
Populating secluded dark sector with ultra-relativistic bubbles
Aleksandr Azatov, Xander Nagels, Miguel Vanvlasselaer +1
We study Dark Matter production during first order phase transitions from bubble-plasma collisions. We focus on scenarios where the Dark Matter sector is secluded and its interacti…
