This analysis extends recent measurements of the jet sub-structure observables based on the SoftDrop algorithm in p+p collisions at √s = 200 GeV in the STAR experiment. We present fully unfolded multi-differential measurements of jet sub-structure observables at the first split and their correlations for jets of different transverse momenta and radii. We compare our measurements to various Monte Carlo models.

The author presents the measurement of correlations between a shared momentum fraction and groomed radius with jet momentum measured by STAR detector at RHIC.

These are interesting results and written well. I recommend it for publication in the current form.
