Abstract

A search has been made for new particles with charge Q=2/3, 1, 4/3, 5/3 produced in e⁺e^--reactions at PETRA. The energy range was E_cm=27-35 GeV. No such particles were found. Upper limits for the cross-section depending on the assumed mass and production spectrum are given. For Q=2/3 quarks with mass less than 12 GeV/c², upper limits {Mathematical expression} (90% C.L.) are obtained both for inclusive and exclusive production. For the lifetime of the B-meson (m_B=5GeV/c²) an upper limit τ≦2×10^-9s is obtained.
