${{\boldsymbol B}_{{c}}^{+}}$ MEAN LIFE INSPIRE search

``OUR EVALUATION'' is an average using rescaled values of the data listed below. The average and rescaling were performed by the Heavy Flavor Averaging Group (HFLAV) and are described at https://hflav.web.cern.ch/. The averaging/rescaling procedure takes into account correlations between the measurements.

1  The lifetime is measured using the decays ${{\mathit B}_{{c}}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \pi}^{+}}$ and ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit K}^{+}}$ .
2  Also measures the width difference $\Delta \Gamma $ = ${\Gamma}_{{\mathit B}_{{c}}^{+}}−$ ${\Gamma}_{{\mathit B}^{+}}$ = $4.46$ $\pm0.14$ $\pm0.07$ mm${}^{-1}~$c.
3  Uses fully reconstructed ${{\mathit B}_{{c}}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \pi}^{+}}$ decays.
4  Measured using ${{\mathit B}_{{c}}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \mu}^{+}}{{\mathit \nu}_{{\mu}}}{{\mathit X}}$ decays.
5  The lifetime is measured from the ${{\mathit J / \psi}}{{\mathit e}}$ decay vertices.
