Search for a $\pi \Lambda N-\pi \Sigma N$ dibaryon in [email protected] GeV

Abstract

This work is dedicated to the search for a $\pi \Lambda N-\pi \Sigma N$ resonance $\mathcal{Y}$ with the quantum numbers ($Y,I,J^P$) = (1,3/2,$2^{+}$). The double charged $\Sigma (1385)N-\Delta (1232)Y$ quasibound state was looked for in the reaction $pp\to {\mathcal{Y}}^{++}{K}^0$ with its unique decay into ${\Sigma }^{+}$ and proton measured with the HADES setup at a kinetic beam energy of 3.5 GeV. The analysis including background determination and a description of the data with a $K_S^0$ Monte Carlo cocktail are presented.
