Measurement of mass and lifetime of B-hadrons at ATLAS

Mostrar otras versiones (1)

Using data collected in 2011, the ATLAS Collaboration has measured the lifetime and mass of the Lambda_b, the lifetimes and masses of the B_d and B_s mesons, and the average lifetime for inclusive B production at 7 TeV center of mass energy in proton-proton collisions. The mass of the Lambda_b is me...

Sumario:Using data collected in 2011, the ATLAS Collaboration has measured the lifetime and mass of the Lambda_b, the lifetimes and masses of the B_d and B_s mesons, and the average lifetime for inclusive B production at 7 TeV center of mass energy in proton-proton collisions. The mass of the Lambda_b is measured with a precision above the world average. Polarization measurements of the Lambda_b are planned.
