LHCb - Doubly charmed baryon searches and studies at LHC

We present the latest results on the doubly charmed baryon searches and studies performed at the LHCb experiment. Precise studies of the properties of the doubly charmed baryon $\Xi_{cc}^{++}$, such as its lifetime, production, mass and decays, are presented. Recent search for its isospin partner, $\Xi_{cc}^{+}$ baryon, in $\Lambda_{c}^{+} K^{-} \pi^{+}$ decays using full Run1+Run2 data sample collected by the LHCb experiment, where no significant signal has been observed and upper limit on the production cross section times branching fraction with respect to the $\Xi_{cc}^{++} \rightarrow \Lambda_{c}^{+} K^{-} \pi^{+} \pi^{+}$ decay has been set, is discussed. Finally, ongoing studies and analyses are described, namely searches for the $\Xi_{cc}^{+}$ and $\Omega_{cc}^{+}$ baryons in more decay channels and preparation for Run3 data taking
