In this work, we investigate the double-heavy molecular pentaquark states with the quark contents ccsss¯, bbsss¯, and bcsss¯ by using the coupled channel approach. The extended local hidden gauge Lagrangians are used to obtain the meson-baryon interactions by exchanging the vector mesons. We predict some candidates for the molecular states with the quantum numbers I(JP)=0(1/2−,3/2−,5/2−), whose binding energies are of the order of 20–30 MeV and whose widths are all less than 8 MeV. These predicted exotic double-heavy molecular pentaquark states may be accessible in future experiments such as LHCb. Published by the American Physical Society 2024
