Measurement of the $\hat{I}{›}_c^{+}$ lifetime

Belle II Collaboration, F. Abudinén, L. Aggarwal +360

An absolute measurement of the $\hat{I}{›}_c^{+}$ lifetime is reported using $\hat{I}{›}_c^{+}\to p{K}^{-}\ddot{I}{€}^{+}$ decays in events reconstructed from data collected by the Belle II experiment at t…
