Description
The Doubly charmed baryon $\Xi_{cc}^{++}$ was observed by the LHCb experiment in 2017. Measurements of its properties will allow for precise tests of QCD, the theory of strong interactions, in a unique environment. In this talk, we present the first measurement of the lifetime of the doubly charmed baryon $\Xi_{cc}^{++}$, with signals reconstructed in the final states $\Lambda_c^+ K^- \pi^+ \pi^+$ from the data sample collected by the LHCb experiment, corresponding to an integrated luminosity of 1.7 fb$^{-1}$. The measured $\Xi_{cc}^{++}$ lifetime is $0.256^{+0.024}_{-0.022} \pm 0.014$ ps.
