Masses of the Bottom-Charm Hybrid bGc States

الأصل · EN

QCD sum rules are used to study the mass spectrum of bottom-charm hybrid bGc systems. The correlation functions and the spectral densities are calculated up to dimension six condensates at leading order of αₛ for several Jᵖ quantum numbers. After performing the QCD sum rule analysis, we predict the masses of the Jᵖ=0⁻, 0⁺, 1⁻, 1⁺, 2⁻, 2⁺ bottom-charm hybrids. These mass predictions show a similar supermultiplet structure as the bottomonium and charmonium hybrids. Using the QCD sum-rule mass predictions we analyze the possible hadronic decay patterns of the cGc, bGc and bGb hybrids including the open-flavour and hidden-flavour mechanisms.
