Sensitivity study of anomalous HZZ couplings at a future Higgs factory

2019, 43(10): 103001. doi: 10.1088/1674-1137/43/10/103001
Abstract:
We study the sensitivity of constraining the model independent HZZ coupling based on the effective theory up to dimension-6 operators at a future Higgs factory. Using the current conceptual design parameters of the Circular Electron Positron Collider...
Symmetry properties of nonlocal quark bilinear operators on a Lattice (LP3 Collaboration)

2019, 43(10): 103101. doi: 10.1088/1674-1137/43/10/103101
Abstract:
Using symmetry properties, we determine the mixing pattern of a class of nonlocal quark bilinear operators containing a straight Wilson line along a spatial direction. We confirm the previous study that mixing among the lowest dimensional operators, ...
Dark matter and LHC phenomenology of a scale-invariant scotogenic model
Chao Guo, Shu-Yuan Guo, Yi Liao
2019, 43(10): 103102. doi: 10.1088/1674-1137/43/10/103102
Abstract:
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 realized via the Coleman-Weinberg mechanism in a classically scale in...

Motivated by the rapid development of heavy flavor physics experiments, we study the tree-dominated nonleptonic \begin{document}$ \bar{B}_{u,d,s}^* \to D_{u,d,s}^*V $\end{document} (\begin{document}$ V = D^{*-},D_s^{*-},K^{*-},{\rho}^- $\end{document...
A note on scalar meson dominance
Y. Ünal, Ulf-G. Meißner
2019, 43(10): 103105. doi: 10.1088/1674-1137/43/10/103105
Abstract:
We consider chiral perturbation theory with an explicit broad σ-meson and study its contribution to the scalar form factors of the pion and the nucleon. Our goal is to learn more about resonance saturation in the scalar sector.
Consistency check on the fundamental and alternative flux operators in loop quantum gravity
Jinsong Yang, Yongge Ma
2019, 43(10): 103106. doi: 10.1088/1674-1137/43/10/103106
Abstract:
There are different constructions of the flux of triad in loop quantum gravity, namely the fundamental and alternative flux operators. In parallel to the consistency check on the two versions of operator by the algebraic calculus in the literature, w...

Prediction of the cross-sections of isotopes produced in deuteron-induced spallation of long-lived fission products
Guanming Yang, Suyang Xu, Mengting Jin, Jun Su
2019, 43(10): 104101. doi: 10.1088/1674-1137/43/10/104101
Abstract:
The spallation cross-section data for the long-lived fission products (LLFPs) are scarce but required for the design of accelerator driven systems. In this paper, the isospin dependent quantum molecular dynamics model and the statistical code GEMINI ...

Abstract:
Excited states of odd-odd nucleus 92Nb and odd-A nucleus 93Nb were populated in the 6Li+ 89Y reaction with an incident energy of 34 MeV. The processes that produce 92,93Nb and can be measured by a combination of light charged particle and gamma ray m...

Abstract:
This study investigates the structural properties of super-heavy nuclei with Z = 130 by adopting the relativistic mean-field (RMF) theory within an axially deformed oscillator basis with the NL3 force parameter set. We study the binding energies, qua...

Abstract:
It is widely believed that the screening mechanism is an essential feature for the modified gravity theory. Although this mechanism has been examined thoroughly in the past decade, their analyses are based on a conventional fluid prescription for the...
Matter effects and coherent effect of neutrinos produced from γ-ray bursts
Kuan Liu, Chun-Sheng An, Xin Li, Hai-Nan Lin

Abstract:
Neutrinos produced from \begin{document}$\gamma$\end{document}-ray bursts (GRBs) carry significant physical information. The electron density in the GRBs outflow is very large. In this study, we calculate the matter effect on neutrinos when they prop...

Abstract:
As a charged fermion drops into a BTZ black hole, the laws of thermodynamics and the weak cosmic censorship conjecture are investigated in both the normal and extended phase space, where the cosmological parameter and renormalization length are regar...
