Measurement of the B+_c Meson Lifetime Using B+_c -->J/psi e+nu_e

We present a measurement of the B{sub c}{sup +} meson lifetime in the decay mode B{sub c}{sup +}{yields}J/{psi}e{sup +}{nu}e using the Collider Detector at Fermilab 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, w...

Description
Summary:We present a measurement of the B{sub c}{sup +} meson lifetime in the decay mode B{sub c}{sup +}{yields}J/{psi}e{sup +}{nu}e using the Collider Detector at Fermilab 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, we reconstruct J/{psi}e{sup +} pairs with invariant mass in the kinematically allowed range 4
