Fermion bound states in geometrically deformed backgrounds
D. Bazeia, A. Mohammadi, D. C. Moreira
2019, 43(1): 013101. doi: 10.1088/1674-1137/43/1/013101
Abstract:
This work deals with the behavior of fermions in the background of kinklike structures in the two-dimensional spacetime. The kinklike structures appear from bosonic scalar field models that engender distinct profiles and interact with the fermion fie...
Probing anomalous top-Higgs couplings at the HL-LHC via HWW* decay channels
Yao-Bei Liu, Stefano Moretti
2019, 43(1): 013102. doi: 10.1088/1674-1137/43/1/013102
Abstract:
We study the prospects of probing the anomalous tHq (q=u, c) couplings via SS2L or 3L signatures at the High Luminosity (HL-LHC) run of the 14 TeV CERN collider. We focus on signals of the tH associated production followed by the decay modes tb\begi...
Doubly-charged scalar in four-body decays of neutral flavored mesons
Tian-Hong Wang, Geng Li, Yue Jiang, Guo-Li Wang
2019, 43(1): 013103. doi: 10.1088/1674-1137/43/1/013103
Abstract:
We study the four-body decays of neutral flavored mesons, including K0, D0, B0, and Bs0. These processes, which could be induced by a hypothetical doubly-charged scalar particle, do not conserve the lepton number. Assuming, as an example, that the ma...
A discussion on vacuum polarization correction to the cross-section of e+e-γ*/ψμ+μ-
Hong-Dou Jin, Li-Peng Zhou, Bing-Xin Zhang, Hai-Ming Hu
2019, 43(1): 013104. doi: 10.1088/1674-1137/43/1/013104
Abstract:
Vacuum polarization is a part of the initial-state radiative correction for the cross-section of e+e- annihilation processes. In the energy region in the vicinity of narrow resonances J/ψ and ψ(3686), the vacuum polarization contribution from the res...
A non-relativistic model for the [cc] [cc] tetraquark
V.R. Debastiani, F.S. Navarra
2019, 43(1): 013105. doi: 10.1088/1674-1137/43/1/013105
Abstract:
We use a non-relativistic model to study the spectroscopy of a tetraquark composed of [cc] [cc] in a diquark-antidiquark configuration. By numerically solving the Schrödinger equation with a Cornell-inspired potential, we separate the four-body probl...
Entanglement in simple spin networks with a boundary
Yi Ling, Meng-He Wu, Yikang Xiao
2019, 43(1): 013106. doi: 10.1088/1674-1137/43/1/013106
Abstract:
We investigate the bipartite entanglement for the boundary states in a simple type of spin networks with dangling edges, in which the two complementary parts are linked by two or more edges. Firstly, the spin entanglement is considered in the absence...
Sonic velocity in holographic fluids and its applications
Yapeng Hu, Yu Tian, Xiaoning Wu, Huaifan Li, Hongsheng Zhang
2019, 43(1): 013107. doi: 10.1088/1674-1137/43/1/013107
Abstract:
Gravity/fluid correspondence acts as an important tool in investigating the strongly correlated fluids. We carefully investigate the holographic fluids at the finite cutoff surface by considering different boundary conditions in the scenario of gravi...
Mixed electroweak-QCD corrections to e+e-μ+μ-H at CEPC with finite-width effect
Wen Chen, Feng Feng, Yu Jia, Wen-Long Sang
2019, 43(1): 013108. doi: 10.1088/1674-1137/43/1/013108
Abstract:
The associated production of Higgs boson with a muon pair, e+eμ+μ-H, is one of the golden channels to pin down the properties of the Higgs boson in the prospective Higgs factories exemplified by CEPC. The projected accuracy of the corresponding c...
Near horizon OTT black hole asymptotic symmetries and soft hair
B. Cvetković, D. Simić
2019, 43(1): 013109. doi: 10.1088/1674-1137/43/1/013109
Abstract:
We study the near horizon geometry of both static and stationary extremal Oliva Tempo Troncoso (OTT) black holes. For each of these cases, a set of consistent asymptotic conditions is introduced. The canonical generator for the static configuration i...

A simple description of the temperature dependence of the width of the fission-fragment mass yield in 197Au and 209Bi at intermediate energies
V. Yu. Denisov, O. A. Belyanovska, V. P. Khomenkov, I. Yu. Sedykh, K. M. Sukhyy
2019, 43(1): 014101. doi: 10.1088/1674-1137/43/1/014101
Abstract:
A simple approach is proposed to describe the experimental data for the widths of the fission-fragment mass yields in 197Au and 209Bi at low and intermediate energies. The approach is based on the expressions for the temperature dependence of the wid...
Double heavy tri-hadron bound state via delocalized π bond
Li Ma(马力), Qian Wang(王倩), Ulf-G. Meißner
2019, 43(1): 014102. doi: 10.1088/1674-1137/43/1/014102
Abstract:
The number of exotic candidates that are beyond the conventional quark model has increased dramatically over recent decades. Some of these can be viewed as analogues of the deuteron. Similarly, the existence of the triton indicates that bound states ...
Alternative methods for measurement of the global polarization of Λ hyperons
Irfan Siddique, Zuo-tang Liang, Michael Annan Lisa, Qun Wang, Zhang-bu Xu
2019, 43(1): 014103. doi: 10.1088/1674-1137/43/1/014103
Abstract:
We propose alternative methods for measurement of the global polarization of Λ hyperons. These methods involve event averages of proton and Λ momenta in the laboratory frame. We carry out simulations using these methods and show that all of them work...
Empirical pairing gaps and neutron-proton correlations
B. S. Ishkhanov, S. V. Sidorov, T. Yu. Tretyakova, E. V. Vladimirova
2019, 43(1): 014104. doi: 10.1088/1674-1137/43/1/014104
Abstract:
Analysis of various mass formulas related to neutron-proton correlations in atomic nuclei is carried out. Using the example of the N=Z chain it is shown that for self-adjoint nuclei various formulas proposed in literature for estimating the np pairin...
