# Possible indication of narrow baryonic resonances produced in the 1720 - 1790 MeV mass region

Abstract : Signals of two narrow structures at M=1747 MeV and 1772 MeV were observed in the invariant masses MpX and M +X of the pp $\rightarrow$ ppX and pp$\rightarrow$p +X reactions respectively. Many tests were made to see if these structures could have been produced by experimental artefacts. Their small widths and the stability of the extracted masses lead us to conclude that these structures are genuine and may correspond to new exotic baryons. Several attempts to identify them, including the possible missing baryons approach, are discussed.
