Baryon Spectroscopy at COMPASS

Diffractive dissociation of the beam proton is one of the dominant processes for the 190GeV$/c$ positive hadron beam impinging on a liquid hydrogen target in COMPASS. The status of the analysis of the reactions $pp\rightarrow$ $p_{f}$ $\pi^{+}\pi^{-}p_{s}$ and $pp\rightarrow$ $p_{f}$ $K^{+}K^{−}p_{s...

Sumario:Diffractive dissociation of the beam proton is one of the dominant processes for the 190GeV$/c$ positive hadron beam impinging on a liquid hydrogen target in COMPASS. The status of the analysis of the reactions $pp\rightarrow$ $p_{f}$ $\pi^{+}\pi^{-}p_{s}$ and $pp\rightarrow$ $p_{f}$ $K^{+}K^{−}p_{s}$ will be presented, where dominant features of the light baryon spectrum become clearly visible. Furthermore, partial-wave analysis techniques to disentangle these spectra are discussed.
