Measurement of the B(c)+ meson lifetime using B(c)+ ---> J/psi e+ nu(e)
Abstract
The authors present a measurement of the B{sub c}{sup +} meson lifetime in the semileptonic decay mode B{sub c}{sup +} {yields} J/{psi}e{sup +}{nu}{sub e} using the CDF II detector at the Fermilab Tevatron Collider. From a sample of about 360 pb{sup -1} of p{bar p} collisions at {radical}s = 1.96 TeV, they reconstruct J/{psi}e{sup +} pairs with invariant mass in the kinematically allowed range 4 < M{sub J/{psi}e} < 6 GeV/c{sup 2}. A fit to the decay-length distribution of 238 signal events yields a measured B{sub c}{sup +} meson lifetime of 0.463{sub -0.065}{sup +0.073}(stat) {+-} 0.036(syst) ps.
