Mass and lifetime measurements of bottom and charm baryons in p(p)over-bar collisions at pffisffi root s=1.96 TeV Academic Article uri icon

abstract

  • We report on mass and lifetime measurements of several ground state charmed and bottom baryons, using a data sample corresponding to 9.6fb-1 from pp collisions at s=1.96TeV and recorded with the Collider Detector at Fermilab. Baryon candidates are reconstructed from data collected with an online event selection designed for the collection of long-lifetime heavy-flavor decay products and a second event selection designed to collect J/ +- candidates. First evidence for the process b-c0- is presented with a significance of 3.3. We measure the following baryon masses: M(c0)=2470.850.24(stat) 0.55(syst)MeV/c2,M(c+)=2468.000.18(stat)0.51(syst) MeV/c2,M(b)=5620.150.31(stat)0.47(syst)MeV/c2,M(b-)= 5793.41.8(stat)0.7(syst)MeV/c2,M(b0)=5788.74.3(stat) 1.4(syst)MeV/c2,andM(b-)=6047.53.8(stat)0.6(syst) MeV/c2.The isospin splitting of the b-,0 states is found to be M(b-)-M(b0)=4.74.7(stat)0.7(syst)MeV/c2. The isospin splitting of the c0,+ states is found to be M(c0)-M(c+)=2. 850.30(stat)0.04(syst)MeV/c2. The following lifetime measurements are made: (b)=1.5650.035(stat)0. 020(syst)ps,(b-)=1.320.14(stat)0.02(syst)ps, (b-)=1.66-0.40+0.53(stat)0.02(syst)ps. 2014 American Physical Society.
