Sumario: | <!--HTML-->Due to recent advances in jet finding techniques and larger data samples, measurements of inclusive or recoil jets with large resolution parameters are now experimentally accessible via semi-inclusive hadron-jet or machine learning techniques, the latter of which enables the measurement of charged jet spectra down to low jet transverse momentum for jet resolution parameters up to $R=0.6$. By encompassing additional jet and medium response phase space, jet substructure measurements in these large R jets can provide further constraints on jet and medium properties. Of particular interest is the search for large transverse momentum kicks which may indicate the presence of point-like scatters within the QGP. We explore the jet substructure of inclusive and recoil jets in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV, utilizing Soft Drop and other grooming methods, as well as the Lund Plane, in order to access the hardest $k_{\mathrm{T}}$ splitting. |
