Abstract

Motivated by the very recent discovery of fully open-flavor exotic states X-0(2900) and X-1(2900) by the LHCb collaboration [1], we study possible interpretations of these exotic states by QCD sum rules method. We have calculated mass and decay constant by traditional QCD sum rules analysis and Monte-Carlo based analysis. X-0(2900) and X-1(2900) are studied in molecular and diquark-antidiquark tetraquark pictures, respectively. Obtained mass results agree well with the masses observed in the experiment. We also made a Monte-Carlo based analysis within QCD sum rules for the mass and decay constant distributions to investigate the possible assignments for the structures of X-0(2900) and X(1)2900).
