Studying the $${\bar{D}}_1K$$ D ¯ 1 K molecule in the Bethe–Salpeter equation approach
Abstract We interpret the $$X_1(2900)$$ X 1 ( 2900 ) as an S-wave $${\bar{D}}_1K$$ D ¯ 1 K molecular state in the Bethe–Salpeter equation approach with the ladder and instantaneous approximations for the kernel. By solving the Bethe–Salpeter equation numerically with the kernel containing one-partic...
