Sommerfeld enhancement for puffy self-interacting dark matter
Wenyu Wang, Wu-Long Xu, Jin Min Yang +2
We examine the Sommerfeld enhancement effect for the puffy self-interacting dark matter. We find out two new parameters to classify the self-scattering cross section into the Born,…
Direct detection of cosmic ray-boosted puffy dark matter
Wenyu Wang, Wu-Long Xu, Jin Min Yang +1
For the light relativistic dark matter (DM) boosted by high energy cosmic ray, its scattering cross section with the nucleon is sensitively dependent on the momentum-transfer and s…
Direct detection of finite-size dark matter via electron recoil
Wenyu Wang, Wu-Long Xu, Jin Min Yang
In direct dark matter (DM) detection via scattering off the electrons, the momentum transfer plays a crucial role. Previous work showed that for self-interacting DM, if the DM part…
Revisiting Puffy Dark Matter with Novel Insights: Partial Wave Analysis
Wenyu Wang, Wu-Long Xu, Jin Min Yang +1
We present a comprehensive study on the self-interaction cross-section of puffy dark matter (DM) particles, which have a significant intrinsic size compared to their Compton wavele…
A hidden self-interacting dark matter sector with first order cosmological phase transition and gravitational wave
Wenyu Wang, Wu-Long Xu, Jin Min Yang
A dark scalar mediator can easily realize the self-interacting dark matter scenario and satisfy the constraint of the relic density of the dark matter. When the hidden sector is hi…
Cosmological phase transitions, gravitational waves and self-interacting dark matter in the singlet extension of MSSM
Wenyu Wang, Ke-Pan Xie, Wu-Long Xu +1
In the minimal supersymmetric standard model (MSSM) extended by a singlet superfield, when the coupling between the singlet sector and the MSSM sector is tiny, the singlet sector c…
The Realistic Scattering of Puffy Dark Matter
Wenyu Wang, Wu-Long Xu, Bin Zhu
If dark matter has a finite size, the intrinsic interaction responsible for the structure formation is inevitable from the perspective of dark matter self-scattering. To describe t…
New general DBI action, its solution to the paradox of the conversion of kinetic and potential energy in equal rights and their true applications to inflationary cosmology
Xiaokun Yang, Wu-Long Xu, Yong-Chang Huang
The Dirac-Born-Infeld (DBI) field theory in string theory is important and can provide the field of the universe's inflation. At the same time, it provides a causal mechanism for g…
Revised parameter in Curvaton Scenario
Lei-Hua Liu, Bin Liang, Ya-Chen Zhou +3
We revise the Non-Gaussianity of canonical curvaton scenario with a generalized formalism, in which it could handle the generic potentials. In various curvaton models, the ene…
The running curvaton
Lei-Hua Liu, Wu-Long Xu
Inspired by \cite{Jiang:2018uce}, we propose a similar curvaton mechanism whose realization occurs in preheating process, in which the effective mass is running (its potential cons…
Dynamics of domain wall in charged AdS dilaton black hole spacetime
Wu-Long Xu, Yong-Chang Huang
For the dimensional FRW domain wall universe induced by dimensional charged dilaton black hole, its movement formula in the bulk can be rewrite as the expansion or collap…
Dynamic domain wall in charged dilaton black hole spacetimes
Wu-Long Xu, Ai-Chen Li, Yong-Chang Huang
In this paper we study the dynamics of dimensional domain wall universe embedded in a dimensional charged dilaton black hole bulk with the non-asymptotically flat and no…
Linear Stability Analysis of Evolving Thin Shell Wormholes
Ai-chen Li, Wu-long Xu, Ding-fang Zeng
Using ideas from the brane world cosmological perturbation theory, we make linear stability analysis of dynamic thin shell wormholes constructed by cutting-and-pasting two building…
