Description
The measurement of jet shapes such as the angularity, the momentum dispersion and the difference between the leading and subleading jet constituents track momentum will be presented. The measurements were done in pp collisions at $\sqrt s$ = 5 TeV and will be compared to previous measurements by ALICE at $\sqrt s$ = 7 TeV. These jet structure observables probe the radiation pattern of jets. Jets are reconstructed using anti-$k_{\rm T}$ algorithm and for different jet resolution $R=0.2,0.4$ and 0.7. Detector effects are corrected via two dimensional unfolding and the final results are presented in the $p_{T}$ range 20-40 and 40-60 GeV/$c$. The results are also compared to different Montecarlo calculations. As an outlook, the same measurements will be performed in Pb--Pb collisions at $\sqrt{s_{NN}}=$ 5.02 TeV to study medium-induced modification of the jet shape.
