We present the first direct calculation on the gravitational form factors (GFFs) of the N → ∆ transition using an analytic method, the QCD light-cone sum rules. The matrix element of the quark part of the energy momentum tensor current sandwiched

The LHCb Collaboration recently reported the observation of a new excited bottom baryon $\Xi_b(6227)^0$ and announced an improvement in the measurements related to the previously observed $\Xi_b(6227)^-$ state. We conduct an analysis for $\Xi_b(6227)

The spectroscopic properties of single heavy spin-1/2 $\Lambda_{Q}$, $\Sigma_{Q}$, $\Xi^{(\prime)}_{Q}$ and $ \Omega_{Q}$ baryons are investigated at finite temperature in the framework of thermal QCD sum rule. We discuss the behavior of the mass and

Recently the observation of a new pentaquark state, the hidden-charmed strange ${P}_{cs}(4459{)}^{0}$, was reported by the LHCb Collaboration. The spin-parity quantum numbers of this state were not determined as a result of insufficient statistics. T

The mass, coupling and width of the newly observed charged resonance $$ Z_{c}^{-}(4100)$$ Zc-(4100) are calculated by treating it as a scalar four-quark system with a diquark–antidiquark structure. The mass and coupling of the state $$ Z_{c}^{-}(41

The spectroscopic parameters and partial decay widths of the light mesons a 0 ( 980 ) and K 0 ⁎ ( 800 ) are calculated by treating them as scalar diquark–antidiquark states. The masses and couplings of the mesons are found in the framework of QCD

We calculate the magnetic dipole moment of the newly observed charged hidden-charmed open strange $ Z_{cs}(3985)^- $ state, recently observed by BESIII Collaboration. Based on the information provided by the experiment and theoretical studies followe
