Özet
Using a sample of about 10 billion J/psi events with the BESIII detector, we search for the weak decays of J/psi -> (D) over bar (0)pi(0) + c.c., J/psi -> (D) over bar (0)eta + c.c., J/psi -> (D) over bar (0)rho(0) + c.c., J/psi -> D-pi(+) + c.c., and J/psi -> (D) over bar (-)rho(+) + c.c., Since no significant signal is observed, we set the upper limits of the branching fractions of these decays to be B(J/psi -> (D) over bar (0)pi(0) + c.c.) < 4.7 x 10(-7), B(J/psi -> <(D)over bar>(0)eta + c.c.) < 6.8 x 10(-7), B(J/psi -> <(D)over bar>(0)rho(0) + c.c.) < 5.2x10(-7), B(J/psi -> <(D)over bar>(-)pi(+) c.c.) < 7.0 x 10(-8), and B(J/psi -> <(D)over bar>(-)rho(+) + c.c.) < 6.0 x 10(-7) at the 90% confidence level.
