Contributions to the Muon from a Three-Form Field
Da Huang, Yong Tang, Yue-Liang Wu
We examine contributions to the muon dipole moment from a 3-form field , which naturally arises from many fundamental theories, such as the string theory and the hyperunif…
Dark Matter Production in Weyl Inflation
Qing-Yang Wang, Yong Tang, Yue-Liang Wu
Dark matter and inflation are two key elements to understand the origin of cosmic structures in modern cosmology, and yet their exact physical models remain largely uncertain. The…
Semi-annihilating Dark Matter for XENON1T Excess
P. Ko, Yong Tang
The recently reported result from XENON1T experiment indicates that there is an excess with significance in the electronic recoil events. Interpreted as new physics, new sou…
Gravitational Production of Hidden Photon Dark Matter in Light of the XENON1T Excess
Kazunori Nakayama, Yong Tang
Recently, the XENON1T experiment has reported an excess in the electronic recoil events. The excess is consistent with the interpretation of absorption of 3keV bosonic dark matter,…
Weyl Scaling Invariant Gravity for Inflation and Dark Matter
Yong Tang, Yue-Liang Wu
Inflation in the early universe can generate the nearly conformal invariant fluctuation that leads to the structures we observe at the present. The simple viable Starobinsky …
Conformal -attractor Inflation with Weyl Gauge Field
Yong Tang, Yue-Liang Wu
Conformal scaling invariance should play an important role for understanding the origin and evolution of universe. During inflation period, it appears to be an approximate symmetry…
Production of Purely Gravitational Dark Matter: The Case of Fermion and Vector Boson
Yohei Ema, Kazunori Nakayama, Yong Tang
We consider the simplest possibility for a model of particle dark matter in which dark matter has only gravitational interaction with the standard model sector. Even in such a case…
Weyl Symmetry Inspired Inflation and Dark Matter
Yong Tang, Yue-Liang Wu
Motivated by the Weyl scaling gauge symmetry, we present a theoretical framework to explain cosmic inflation and dark matter simultaneously. This symmetry has been resurrected in r…
WIMP dark matter in the parity solution to the strong CP problem
Junichiro Kawamura, Shohei Okawa, Yuji Omura +1
We extend the Standard Model (SM) with parity symmetry, motivated by the strong CP problem and dark matter. In our model, parity symmetry is conserved at high energy by introducing…
Stochastic Gravitational Waves from Particle Origin
Kazunori Nakayama, Yong Tang
We propose that there may be a substantial stochastic gravitational wave background from particle origin, mainly from the gravitational three-body decay of the inflaton. The emitte…
Production of Purely Gravitational Dark Matter
Yohei Ema, Kazunori Nakayama, Yong Tang
In the purely gravitational dark matter scenario, the dark matter particle does not have any interaction except for gravitational one. We study the gravitational particle productio…
Axion-Photon Conversion and Effects on 21cm Observation
Takeo Moroi, Kazunori Nakayama, Yong Tang
Recently the EDGES experiment reported an enhanced 21cm absorption signal in the radio wave observation, which may be interpreted as either anomalous cooling of baryons or heating…
On Thermal Gravitational Contribution to Particle Production and Dark Matter
Yong Tang, Yue-Liang Wu
We investigate the particle production from thermal gravitational annihilation in the very early universe, which is an important contribution for particles that might not be in the…
Hidden Charged Dark Matter and Chiral Dark Radiation
P. Ko, Natsumi Nagata, Yong Tang
In the light of recent possible tensions in the Hubble constant and the structure growth rate between the Planck and other measurements, we investigate a hidden-charged…
Flavor Non-universality Gauge Interactions and Anomalies in B-Meson Decays
Yong Tang, Yue-Liang Wu
Motivated by flavor non-universality and anomalies in semi-leptonic B-meson decays, we present a general and systematic discussion about how to construct anomaly-free gauge…
Gravitino/Axino as Decaying Dark Matter and Cosmological Tensions
Koichi Hamaguchi, Kazunori Nakayama, Yong Tang
In supersymmetric axion models, if the gravitino or axino is the lightest SUSY particle (LSP), the other is often the next-to-LSP (NLSP). We investigate the cosmology of such a sce…
Residual Non-Abelian Dark Matter and Dark Radiation
P. Ko, Yong Tang
We propose a novel particle physics model in which vector dark matter (VDM) and dark radiation (DR) originate from the same non-Abelian dark sector. We show an illustrating example…
Light dark photon and fermionic dark radiation for the Hubble constant and the structure formation
P. Ko, Yong Tang
Motivated by the tensions in the Hubble constant and the structure growth between results and other low redshift measurements, we discuss some cosmological eff…
A Collider for the 750 GeV Resonant State
Min He, Xiao-Gang He, Yong Tang
Recent data collected by ATLAS and CMS at 13 TeV collision energy of the LHC indicate the existence of a new resonant state with a mass of 750 GeV decaying into two photons $γγ…
Pure Gravitational Dark Matter, Its Mass and Signatures
Yong Tang, Yue-Liang Wu
In this study, we investigate a scenario that dark matter (DM) has only gravitational interaction. In the framework of effective field theory of gravity, we find that DM is still s…
Polynomial Spectrum of Gamma Ray from Dark Matter
Yong Tang
In this study, we present some general features of gamma-ray spectra from dark matter. We find that the spectrum with sharp features could appear in a wide class of dark matter mod…
IceCube Events from Heavy DM decays through the Right-handed Neutrino Portal
P. Ko, Yong Tang
The recently observed IceCube PeV events could be due to heavy dark matter (DM) decay. In this paper, we propose a simple DM model with extra gauge symmetry and bridge it…
Dark Higgs Channel for FERMI GeV -ray Excess
P. Ko, Yong Tang
Dark Higgs is very generic in dark matter models where DM is stabilized by some spontaneously broken dark gauge symmetries. Motivated by the FERMI observation of GeV scale $γ…
