Description
Jet production at the LHC provides an invaluable probe of QCD dynamics
ranging from initial-state parton distributions to final-state jet fragmentation
functions. High-precision perturbative calculations for jet substructure have
recently become available, allowing direct comparison of experimental measure-
ments to theory. Measurements of jet substructure therefore offer a direct test of
first-principles theoretical prescriptions for jet formation and fragmentation in
perturbative QCD. Selecting jets containing a heavy-flavor hadron extends tests
of QCD fragmentation to a regime where parton mass and color factors play a
crucial role, probing the limits of modern perturbative calculations. Comparing
inclusive heavy-flavor jet production to jets associated with a Z boson probes
initial state effects. At the same time, performing measurements using a novel
jet flavor tagging algorithm allows tests of perturbative QCD at unprecedented
theoretical precision. The LHCb Collaboration presents recent jet substructure
results at forward rapidity in pp collisions at center-of-mass energy √s = 13
TeV. These jet fragmentation studies are compared to theoretical predictions,
providing new insight on QCD dynamics at forward rapidity and at low and
moderate values of jet transverse momentum
