Abstract This paper investigates charged black holes within the framework of quintic quasi-topological gravity, focusing on their thermodynamics, conserved quantities, and stability. We construct numerical solutions and explore their thermodynamic pr

Abstract For the the quintic quasitopological action which has no well-defined variational principle, we introduced a surface term that for a spacetime with flat boundaries make the action well-defined. Moreover, we investigated the numerical solutio

Abstract Recently, the LHCb Collaboration performed first search for the rare radiative $$\Xi _{b}^{-}\rightarrow \Xi ^{-}\gamma $$ Ξ b - → Ξ - γ decay and put an upper limit, $$\mathcal{B}(\Xi _{b}^{-}\rightarrow \Xi ^{-}\gamma ) < 1.3 \times 1

Abstract We calculate the strong coupling constants among the doubly heavy spin- $$ \frac{3}{2} $$ 3 2 baryons $$\Xi ^*_{QQ}$$ Ξ QQ ∗ and $$\Omega ^*_{QQ}$$ Ω QQ ∗ , with Q and $$ Q' $$ Q ′ being c or b quark, with light vector meson by means

Abstract The doubly charmed $$\Xi _{cc}^{++} (ccu)$$ Ξcc++(ccu) state is the only listed baryon in PDG, which was discovered in the experiment. The LHCb collaboration gets closer to discovering the second doubly charmed baryon $$\Xi _{cc}^{+} (ccd)$

The strong coupling constants are basic quantities that carry information of the strong interactions among the baryon and meson multiplets as well as information on the natures and internal structures of the involved hadrons. These parameters enter t

We calculate the strong coupling constants among the doubly heavy spin-$ \frac{3}{2} $ baryons $\Xi^*_{QQ}$ and $\Omega^*_{QQ}$, with $ Q $ and $ Q' $ being $ c$ or $ b $ quark, with light vector meson by means of the light-cone QCD sum rules. The ma

The strong coupling constants of hadronic multiplets are fundamental parameters which carry information of the strong interactions among participating particles. These parameters can help us construct the hadron-hadron strong potential and gain infor
