Observation of narrow baryon resonance in $p{K}_s^0$ mode in $pA$-interactions at $70GeV/c$ with SVD-2 setup

A. Kubarovsky, V. Popov

We report on the SVD-2 experiment data analysis aimed to search for an exotic baryon state, the ${\Theta }^{+}$-baryon, in a $p{K}_s^0$ decay mode with IHEP U-70 accelerator proton beam at $70…
