We studied $F$-wave bottom mesons in heavy quark effective theory. The available experimental and theoretical data is used to calculate the masses of $F$-wave bottom mesons. The decay widths of bottom mesons are analyzed to find upper…

We present the mass spectra of radial and orbital excited states of singly heavy bottom baryons; $\Sigma_{b}^{+}, \Sigma_{b}^-, \Xi_b^-, \Xi_b^0, \Lambda_b^0$ and $\Omega_b^-$. The QCD motivated hypercentral quark model is employed for the…

In this article, we assume that the $(0^+,1^+)$ strange-bottom mesons are the conventional $b\bar{s}$ mesons, and calculate the electromagnetic coupling constants $d$, $g_1$, $g_2$ and $g_3$ using the light-cone QCD sum rules. Then we study…

The newly observed $\Sigma_b(6097)$ provides us a good chance to further construct the high excited states of the bottom baryon family. In this work, we explain the $\Sigma_b(6097)$ to be a $1P$ state with $J^P=5/2^-$ or $3/2^-$ by giving…

Recent lattice QCD results suggest that the masses of the first two positive parity $B_s$ mesons lie below the BK threshold, similar to the case of $D^*_{s0}(2317)^+$ and $D_{s1}(2460)^+$ mesons. The mass spectrum of $B_s$ mesons seems to…
