Measurements of the groomed and ungroomed jet angularities in pp collisions at $\sqrt{s} = 5.02$ TeV

Understand

The jet angularities are a class of jet substructure observables which characterize the angular and momentum distribution of particles within jets.

• These observables are sensitive to momentum scales ranging from perturbative hard scatterings to nonperturbative fragmentation into final-state hadrons.
• We report measurements of several groomed and ungroomed jet angularities in pp collisions at $\sqrt{s}=5.02$ TeV with the ALICE detector.
• Jets are reconstructed using charged particle tracks at midrapidity ($|\eta| < 0.9$).
