A formalism for the systematic treatment of rapidity logarithms in Quantum Field Theory
A bstractMany observables in QCD rely upon the resummation of perturbation theory to retain predictive power. Resummation follows after one factorizes the cross section into the relevant modes. TheExpand
Parton fragmentation within an identified jet at NNLL
The fragmentation of a light parton i to a jet containing a light energetic hadron h, where the momentum fraction of this hadron as well as the invariant mass of the jet is measured, is described byExpand
Rapidity renormalization group.
We introduce a systematic approach for the resummation of perturbative series which involves large logarithms not only due to large invariant mass ratios but large rapidities as well. A series ofExpand
Two-loop jet function and jet mass for top quarks
We compute the two-loop heavy-quark jet function in the heavy-quark limit. This is one of the key ingredients in next-to-next-to-leading order and next-to-next-to-leading-log order computations ofExpand
The MSR mass and the OΛQCD$$ \mathcal{O}\left({\Lambda}_{\mathrm{QCD}}\right) $$ renormalon sum rule
A bstractWe provide a detailed description and analysis of a low-scale short-distance mass scheme, called the MSR mass, that is useful for high-precision top quark mass determinations, but can beExpand
Fully-unintegrated parton distribution and fragmentation functions at perturbative k⊥
A bstractWe define and study the properties of generalized beam functions (BFs) and fragmenting jet functions (FJFs), which are fully-unintegrated parton distribution functions (PDFs) andExpand
Infrared renormalization-group flow for heavy-quark masses.
A short-distance heavy-quark mass depends on two parameters: the renormalization scale mu and a scale R controlling the absorption of infrared fluctuations. The radius for perturbative correctionsExpand
R evolution: Improving perturbative QCD
Perturbative QCD results in the MS scheme can be dramatically improved by switching to a scheme that accounts for the dominant power law dependence on the factorization scale in the operator productExpand
One-loop Angularity Distributions with Recoil using Soft-Collinear Effective Theory
Angularities are event shapes whose sensitivity to the splitting angle of a collinear emission is controlled by a continuous parameter $b$, with $ -1 < b < \infty$. When measured with respect to theExpand
Synthesis and E.P.R. Spectra of Randomly Oriented Molecules in Some Bis(Thiosemicarbazonato)copper(II) Complexes
Abstract The synthesis and e.p.r. spectra of some bis(thiosemicarbazonato)copper(II) complexes in the polycrystalline state have been described. For the complexes derived from thiosemicarbazones ofExpand
