College Pk: Amer Physical Soc, v. 84, n. 3, p. 7, 2011.1550-7998http://hdl.handle.net/11449/24572The Lambda(b)(udb) baryon is observed in the decay Lambda(b) -> J/psi Lambda using 6.1fb(-1) of p (p) over bar collisions collected with the D0 detector at root s = 1/96 TeV. The production fraction multiplied by the branching fraction for this decay relative to that for the decay B-0 -> J/psi K-s(0) is measured to be 0.345 +/- 0.034(stat) +/- 0.033(syst) +/- 0.003(PDG). Using the world average value of f(b -> B-0) . B(B-0 -> J/psi K-s(0) = (1.74 +/- 0.08) x 10(-5), we obtain f(b -> Lambda(b)) . B(Lambda(b) -> J/psi Lambda) = (6.01 +/- 0.60(stat) +/- 0.58(syst) +/- 0.28(PDG)) x 10(-5). This measurement represents an improvement in precision by about a factor of 3 with respect to the current world average.7engArtigo10.1103/PhysRevD.84.031102WOS:000293556300001Acesso abertoWOS000293556300001.pdf
