Low Primordial Helium as a Probe of Non-Unitary Neutrino Mixing
Shu-Yuan Guo, Jia-Qi Li
The EMPRESS collaboration has reported a primordial helium mass fraction \(Y_P = 0.2402 \pm 0.0040\), which lies more than \(1σ\) below the standard Big Bang Nucleosynthesis predic…
Revisiting neutrino-assisted self-interacting dark matter
Luqi Wang, Shu-Yuan Guo, Xuewen Liu +1
We assess neutrino-assisted dark matter self-scattering in two scalar-mediator realizations by combining mediator-resolved potentials, numerical scattering calculations, thermal re…
Probing the Scotogenic Dirac Model with FIMP Dark Matter and
Shu-Yuan Guo, Man-Yu Zhao
We study a feebly interacting massive particle realization of the Scotogenic Dirac Model in which the lightest neutral fermion serves as a dark matter candidate, produced via…
Footprints of Axion-Like Particle in Pulsar Timing Array Data and James Webb Space Telescope Observations
Shu-Yuan Guo, Maxim Khlopov, Xuewen Liu +3
Several Pulsar Timing Array (PTA) collaborations have recently reported the evidence for a stochastic gravitational-wave background (SGWB), which can unveil the formation of primor…
Can Sterile Neutrino Explain Very High Energy Photons from GRB221009A?
Shu-Yuan Guo, Maxim Khlopov, Lei Wu +1
The LHAASO collaboration has reported their observation of very high energy photons ( TeV) from the gamma-ray burst GRB221009A. The sterile neutrino that involv…
Axion-assisted Resonance Oscillation Rescues the Dodelson-Widrow Mechanism
Shu-Yuan Guo, Xuewen Liu, Bin Zhu
The scale sterile neutrino was a qualified candidate for dark matter particles in the Dodelson-Widrow mechanism. But the mixing angle, needed to provide enough amount of…
Correlating Gravitational Waves with -boson Mass, FIMP Dark Matter, and Majorana Seesaw Mechanism
Xuewen Liu, Shu-Yuan Guo, Bin Zhu +1
We study a minimal extension of the Standard Model by introducing three right-handed neutrinos and a new scotogenic scalar doublet, in which the mass splittings between neutral and…
Observable Signatures of Scotogenic Dirac Model
Shu-Yuan Guo, Zhi-Long Han
In this work, we make a detailed discussion on the phenomenology of the scotogenic Dirac model, which could accommodate the Dirac neutrino mass and dark matter. We have studied the…
Dark matter and LHC phenomenology of a scale invariant scotogenic model
Chao Guo, Shu-Yuan Guo, Yi Liao
We study the phenomenology of a model that addresses the neutrino mass, dark matter, and generation of the electroweak scale in a single framework. Electroweak symmetry breaking is…
Interpreting the Anomaly in the Colored Zee-Babu Model
Shu-Yuan Guo, Zhi-Long Han, Bin Li +2
We consider the feasibility of interpreting the anomaly in the colored Zee-Babu model. The model generates neutrino masses at two loops with the help of a scalar lept…
Hunting for Heavy Majorana Neutrinos with Lepton Number Violating Signatures at LHC
Chao Guo, Shu-Yuan Guo, Zhi-Long Han +2
The neutrinophilic two-Higgs-doublet model (2HDM) provides a natural way to generate tiny neutrino mass from interactions with the new doublet scalar () and s…
Testing Type II Radiative Seesaw Model: from Dark Matter Detection to LHC Signatures
Shu-Yuan Guo, Zhi-Long Han, Yi Liao
We analyse the testability of the type II radiative seesaw in which neutrino mass and dark matter (DM) are related at one-loop level. Under the constraints from DM relic density, d…
Analysis of the heavy quarkonium states and with QCD sum rules
Zhi-Gang Wang
In this article, we take the tensor currents to interpolate the -wave spin-singlet heavy quarkonium states , and study the masses and decay constants…
