Abstract
Hadrons are systems bound by the strong interaction, which is described at the fundamental level by Quantum Chromodynamics (QCD). Several models and techniques, such as constituent-quark models or lattice-QCD calculations, attempt to reproduce the spectrum of b-hadron masses. On the experimental side, while the masses of all expected ground-state mesons are now well measured, baryon data are still sparse. The LHCb experiment at CERN’s Large Hadron Collider is dedicated to bottom physics and CP violation. The first 1.0 fb−1 of pp collisions collected during the 2011 run allows the exploration of the b-baryon Sector with unprecedented precision. We present the most precise measurements of the Λ0b, Ξ−b and Ω−b baryon masses to date.
