Recent results in b-hadron Spectroscopy from CDF and DØ

Integrated luminosities above 1fb−1 at CDF and DØ, as well as new triggers capable of selecting events with high-impact parameter tracks, have been enormously beneficial for the study of b-hadron spectroscopy. The two experiments have reconstructed the mesons decaying into the B(∗)+π− final states as well as L=1 strange bottom mesons decaying into B(∗)+K−. Recently the JP=1/2+ baryons (buu), their isospin partners (bdd), and their JP=3/2+ exited states have been seen in decays to Λbπ±. These discoveries are accompanied by precise mass measurements that can be compared to theoretical predictions. Data samples continue to increase and further progress in b-hadron spectroscopy can be expected from Tevatron data.
