A bstractThe jet fragmentation function describes the longitudinal momentum distribution of hadrons inside a reconstructed jet. We study the jet fragmentation function in proton-proton collisions in the framework of soft-collinear effective theory (SCET). We find that, up to power corrections, the jet fragmentation function can be expressed as the ratio of the fragmenting jet function and the unmeasured jet function. Using renormalization group techniques, we are able to resum large logarithms… 
Towards the understanding of jet shapes and cross sections in heavy ion collisions using soft-collinear effective theory
A bstractWe calculate the jet shape and the jet cross section in heavy ion collisions using soft-collinear effective theory (SCET) and its extension with Glauber gluon interactions in the medium
Analytic and Monte Carlo studies of jets with heavy mesons and quarkonia
A bstractWe study jets with identified hadrons in which a family of jet-shape variables called angularities are measured, extending the concept of fragmenting jet functions (FJFs) to these
Heavy quark jet fragmentation
A bstractIn this paper we study the fragmentation of a parton into a jet containing a heavy quark. When heavy quarks are involved in a jet, the quark mass can lead to a numerically significant
Jet charge modification in finite QCD matter
Jet production and jet substructure modification in heavy-ion collisions have played an essential role in revealing the in-medium evolution of parton showers and the determination of the properties
Phenomenology with a recoil-free jet axis: TMD fragmentation and the jet shape
A bstractWe study the phenomenology of recoil-free jet axes using analytic calculations and Monte Carlo simulations. Our focus is on the average energy as function of the angle with the jet axis (the
Transverse momentum spectra at threshold for groomed heavy quark jets
A bstractWe present the transverse momentum spectrum for a heavy hadron at threshold in a groomed jet initiated by a heavy quark. The cross section is doubly differential in the energy fraction of an
Access to photon fragmentation functions in hadronic jet production
We argue that the process $pp \to (\text{jet} \gamma)X$, for which a photon is observed inside a fully reconstructed jet and is treated as part of the jet, offers new probes of the so far little
New Tests of NRQCD from Quarkonia Within Jets
I review the current status of quarkonium production theory based on the non-relativistic QCD factorization formalism (NRQCD). While this theory describes much of the world's data on J/\psi and

Fragmentation in Jets at NNLO
Beam and jet functions in soft-collinear effective theory describe collinear initial- and final-state radiation (jets), and enter in factorization theorems for N-jet production, the Higgs pT

We present an analytical next-to-leading order QCD calculation of the partonic cross sections for the process pp! (jeth)X, for which a specic hadron is observed inside a fully reconstructed jet. In
Fragmentation in jets: Cone and threshold effects
We study the fragmentation of (light) quarks and gluons to hadrons inside a jet of cone size R. This allows for a more exclusive analysis of fragmentation than is currently the case. The shape of
