Abstract:
Pion-induced reactions provide unique opportunities for an unambiguous description of baryonic resonances and their coupling channels by means of a partial-wave analysis. Using the secondary pion beam at SIS18, the two-pion production in the second resonance region has been investigated to unravel the role of the N(1520) 3/2(-) resonance in the intermediate rho-meson production. Results on exclusive channels with one pion (pi(-)p) and two pions (pi(+)pi(-)n, pi(0)pi(-)p) in the final state measured in the pi(-)-p reaction at four different pion beam momenta (0.650, 0.685, 0.733, and 0.786 GeV/c) are presented. The excitation function of the different partial waves and Delta pi, N sigma, and N rho isobar configurations is obtained, using the Bonn-Gatchina partial-wave analysis. The N(1520)3/2(-) resonance is found to dominate the N rho final state with the branching ratio BR = 12.2% +/- 1.9%.
