Open AccessHeavy quark dominance in orbital excitation of singly and doubly heavy baryons
A mechanism of the heavy quark dominance in the orbital excitation is proposed in this paper which is testified to be reasonable for singly and doubly heavy baryons. In the relativistic quark model, an analysi...

Open AccessSearch for physics beyond the standard model in top quark production with additional leptons in the context of effective field theory
A search for new physics in top quark production with additional final-state leptons is performed using data collected by the CMS experiment in proton-proton collisions at

Open AccessHolographic Einstein rings of a Gauss–Bonnet AdS black hole
Based on the AdS/CFT correspondence, we study the holographic Einstein image of a Gauss–Bonnet AdS black hole in the framework of wave optics. Our results show that for the absolute amplitude of total response...

Open AccessStrong decays of \( {P}_{\psi}^N{(4312)}^{+} \) to J/ψ(ηc)p and \( {\overline{D}}^{\left(\ast \right)}{\Lambda}_c \) within the Bethe-Salpeter framework
Based on the effective Lagrangian in the heavy quark limit, we calculate the one-boson-exchange interaction kernel of ...

Open AccessThe S- and P-wave fully charmed tetraquark states and their radial excitations
Inspired by recent progresses in observations of the fully charmed tetraquark states by LHCb, CMS, and ATLAS collaborations, we perform a systematic study of the ground states and the first radial excitations ...

Open AccessQED and accretion flow models effect on optical appearance of Euler–Heisenberg black holes
Taking the quantum electrodynamics (QED) effect into account, we investigate the geometrical-optics appearance of the Euler–Heisenberg (EH) black hole (BH) under the different accretion flows context, which de...

Open AccessDam** signatures at JUNO, a medium-baseline reactor neutrino oscillation experiment
We study dam** signatures at the Jiangmen Underground Neutrino Observatory (JUNO), a medium-baseline reactor neutrino oscillation experiment. These dam** signatures are motivated by various new physics mod...

Open AccessThe mass spectrum and wave functions of the Bc system
The spectrum and relativistic wave functions of Bc system are investigated via solving the complete Salpeter equation. Emphases are put on the study of the partial waves of each JP state. Our study shows that the...

Open AccessGW170817 and GW190425 as hybrid stars of dark and nuclear matter
We propose three scenarios for compact hybrid stars composed of nuclear and dark matter. These hybrid stars could provide alternative interpretations to the LIGO/Virgo events GW170817 and GW190425. To demonstr...

Open AccessThe newly observed state \(D_{s0}(2590)^{+}\)
We choose the Reduction Formula, PCAC and Low Energy Theory to reduce the S matrix of a OZI allowed two-body strong decay involving a light pseudoscalar, the covariant transition amplitude formula with relativist...

Open AccessObservational appearances of a f(R) global monopole black hole illuminated by various accretions
In this paper, we explore three simple models of accretions on a global monopole black hole in f(R) theory, and numerically study the corresponding observational appearances as seen by an observer located at the ...
