摘要：

We investigate the discovery potential of the predicted neutral hidden beauty N*(11052) resonance through pi(-) p scattering within an effective Lagrangian approach. Two reactions pi(-) p -> K-Sigma(+) and pi(-) p -> eta(b)n are studied in this work, with nucleon pole exchange as the background. It is found that the contributions of the N*(11052) resonance give clear peak structures in the magnitude of 1 mu b near the threshold of the N*(11052) in the total cross sections. The numerical results indicate that the center of mass energy W similar or equal to 11-11.1 GeV would be a best energy window for searching the N*(11052) resonance, where the N*(11052) signal can be easily distinguished from the background. The COMPASS experiment at CERN's Super Proton Synchrotron (SPS) with pion beam of similar or equal to 280 GeV will be an ideal platform for searching the super-heavy resonance with hidden beauty, which is hopeful to test the theoretical results.
