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

SVD Collaboration

SVD-2 experiment data have been analyzed to search for an exotic baryon state, the ${\Theta }^{+}$-baryon, in a $p{K}_s^0$ decay mode at $70GeV/c$ on IHEP accelerator. The reaction $pA \to pK…
