Monte-Carlo Based QCD Sum Rules Analysis of $X_0(2900)$ and $X_1(2900)$

Motivated by the very recent discovery of fully open-flavor exotic states $X_0(2900)$ and $X_1(2900)$ by the LHCb Collaboration, we study possible interpretations of these exotic states by QCD Sum Rules method. $X_0(2900)$ and $X_1(2900)$ are studied in molecular and diquark-antidiquark tetraquark pictures, respectively. Obtained results for masses are in good agreement with the observed masses in the experiment. We also made a Monte-Carlo based analysis within QCD Sum Rules for the mass distributions to investigate the possible assignments for the structures of $X_0(2900)$ and $X_1(2900)$.
