Fragmentation in Jets: Cone and Threshold Effects
Massimiliano Procura, Wouter J. Waalewijn
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 cas…
Fully-Unintegrated Parton Distribution and Fragmentation Functions at Perturbative k_T
Ambar Jain, Massimiliano Procura, Wouter J. Waalewijn
We define and study the properties of generalized beam functions (BFs) and fragmenting jet functions (FJFs), which are fully-unintegrated parton distribution functions (PDFs) and f…
Jet Regions from Event Shapes and the N-Jet Soft Function at Hadron Colliders
Teppo T. Jouttenus, Iain W. Stewart, Frank J. Tackmann +1
The N-jettiness event shape divides phase space into N+2 regions, each containing one jet or beam. These jet regions are insensitive to the distribution of soft radiation and, with…
Factorization at the LHC: From PDFs to Initial State Jets (Ph.D. thesis)
Wouter J. Waalewijn
New physics searches at the LHC or Tevatron typically look for a specific number of hard jets, leptons and photons. To obtain an exclusive N-jet sample, one can measure the event s…
The Soft Function for Exclusive N-Jet Production at Hadron Colliders
Teppo T. Jouttenus, Iain W. Stewart, Frank J. Tackmann +1
The N-jettiness event shape divides phase space into N+2 regions, each containing one jet or beam. Using a geometric measure these regions correspond to jets with circular boundari…
Parton Fragmentation within an Identified Jet at NNLL
Ambar Jain, Massimiliano Procura, Wouter J. Waalewijn
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 measure…
