We mainly investigate the LFV Higgs boson decays $h\rightarrow e\mu$, $h\rightarrow e\tau$, $h\rightarrow \mu\tau$ and $\mu-e$ conversion in nuclei within the B-L symmetric SSM. At the same time, the corresponding constraints from the LFV rare decays $\mu\rightarrow e\gamma$, $\tau\rightarrow e\gamma$, $\tau\rightarrow \mu\gamma$, and muon $(g-2)$ are considered to analyze the numerical results.
The mysterious dark energy remains one of the greatest puzzles of modern science. Current detections for it are mostly indirect. The spacetime effects of dark energy can be locally described by the SdSw metric. Understanding these local effects exactly is an essential step towards the direct probe of dark energy. From first principles, we prove that dark energy can exert a repulsive dark force...

Results from a wide range of searches targeting different experimental signatures with and without missing transverse momentum ($E^{miss}_{T}$) are used to constrain a Two-Higgs-Doublet Model (2HDM) with an additional pseudo-scalar mediating the interaction between ordinary and dark matter (2HDM+a). The analyses use up to 139 $fb^{−1}$ of proton-proton...
We study the electromagnetic (EM) decays of X(3823) as the $\psi_2(1^{3}D_{2})$ state by using the relativistic Bethe-Salpeter method. Similarly, the EM decay widths of $\psi_{_2}(n^{3}D_{_2})$, $n=2,3$, are predicted, and we find the dominant decays channels are $\psi_{_2}(n^{3}D_{_2})\rightarrow\chi_{_{c1}}(nP)\gamma$, where $n=1,2,3$. The wave function include different partial waves, which...
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 the circumstance in which the binding force realizes the finite size dark protons, we first use the Eikonal approximation to simplify the convoluted scattering between dark protons into the case at the $t=0$ limit....
