英文摘要	A first measurement of the top quark mass in the decay channel t -> (w -> l nu)(b -> j/psi + x -> mu(+) + mu(-) + x) is presented. the analysis uses events selected from the proton-proton collisions recorded by the cms detector at the lhc at a center-of-mass energy of 8tev. the data correspond to an integrated luminosity of 19.7 fb(-1), with 666 t (t) over bar and single top quark candidate events containing a reconstructed j/psi candidate decaying into an oppositely-charged muon pair. the mass of the (j/psi + l) system, where l is an electron or a muon from w boson decay, is used to extract a top quark mass of 173.5 +/- 3.0 (stat) +/- 0.9 (syst) gev.
