Measurement of $b$ hadron masses in exclusive $J/\psi$ decays with the CDF detector

CDF Collaboration

We measure the masses of $b$ hadrons in exclusively reconstructed final states containing a $J/\psi \to {\mu }^{-}{\mu }^{+}$ decay using $220p{\mathrm{b}}^{-1}$ of data collected by the CDF II experiment.…
