Abstract

Boson resonance production has been studied in quasi-two and three-body final states of pp annihilations at 6.94 GeV/c leading to six and more pions. Evidence is presented for the existence of heavy bosons Xo(3.1), Xo(3.4) and Xo(3.6) seen in the reaction pp → Xoπo. The 3π+- decay mode is observed for the Xo(3.1) and Xo(3.4) bosons and decay mode 4π+- is seen for the Xo(3.4) and Xo(3.6) bosons. The A3 and a G = -1 resonance in the T region are seen to be produced in association with a pion and a vector meson.
