description: Pentaquark states have been extensively investigated theoretically in the context of the constituent quark model. In this paper results of an experimental search for pentaquarks in the \Xim\pim, \Xim\pip, \Xip\pim and \Xip\pip invariant mass spectra in proton-proton interactions at $\sqrt{s}$=17.3~\GeV are presented. Previous possible evidence from the NA49 collaboration of the existence of a narrow \Xim\pim baryon resonance in p+p interactions is not confirmed with almost 10 times greater event statistics. The search was performed using the \NASixtyOne detector which reuses the main components of the NA49 apparatus. No signal was observed with either the selection cuts of NA49 or newly optimised cuts.
description: The papaer quote 33 M events while in reality after describted event cuts number reduced to 26M
