What Do Event Generators Compute? Flux Functionals from Detector Operators
Jack Holguin
Every physical prediction of an event generator is a statement about the hadronic fluxes that can be recorded by particle detectors. By contrast, the formal backbone of modern even…
Studying the Infrared Behaviour of Improved Logarithmic Accuracy Parton Showers with Herwig
Jack Holguin, Simon Plätzer, Michael H. Seymour +1
We have implemented two recently proposed dipole shower algorithms that have next-to-leading-logarithmic accuracy at leading colour in the Herwig event generator. We study their pr…
High precision heavy-boson-jet substructure with energy correlators
Jack Holguin, Ian Moult, Aditya Pathak +2
Energy-correlator-based jet substructure has gained significant attention in recent years. One of the notable applications has been the study of multi-scale jets, where distinct ph…
The one-jettiness distribution contains super-super-leading logarithms
Andrea Banfi, Jeffrey R. Forshaw, Jack Holguin
We show that one-jettiness () in colour-singlet plus jet production suffers from super-leading logarithms starting at order relative to the Born…
Top Quark Mass Extractions from Energy Correlators: A Feasibility Study
Jack Holguin, Ian Moult, Aditya Pathak +3
In a recent article, we proposed an energy correlator-based method to achieve a precision top quark mass extraction from jet substructure, using the -boson mass as a standard ca…
Precision Top Mass Measurement Using Energy Correlators
Jack Holguin, Ian Moult, Aditya Pathak +3
Precision top mass measurements at hadron colliders have been notoriously difficult. The fundamental challenge in the current approaches lies in achieving simultaneously high top m…
Using the as a Standard Candle to Reach the Top: Calibrating Energy Correlator Based Top Mass Measurements
Jack Holguin, Ian Moult, Aditya Pathak +3
The top quark mass is a key parameter of the Standard Model, yet measuring it precisely at the Large Hadron Collider (LHC) is challenging. Inspired by the use of standard candles i…
Seeing Beauty in the Quark-Gluon Plasma with Energy Correlators
Carlota Andres, Fabio Dominguez, Jack Holguin +2
Heavy quarks created in heavy-ion collisions serve as an excellent probe of the produced quark-gluon plasma (QGP). The radiation pattern of jets formed from heavy quarks as they tr…
A Coherent View of the Quark-Gluon Plasma from Energy Correlators
Carlota Andres, Fabio Dominguez, Jack Holguin +2
The ability to measure detailed aspects of the substructure of high-energy jets traversing the quark-gluon plasma (QGP) has provided a new window into its internal dynamics. Howeve…
Report of the Topical Group on Top quark physics and heavy flavor production for Snowmass 2021
Reinhard Schwienhorst, Doreen Wackeroth, Kaustubh Agashe +68
This report summarizes the work of the Energy Frontier Topical Group on EW Physics: Heavy flavor and top quark physics (EF03) of the 2021 Community Summer Study (Snowmass). It aims…
Resolving the Scales of the Quark-Gluon Plasma with Energy Correlators
Carlota Andres, Fabio Dominguez, Raghav Kunnawalkam Elayavalli +3
Jets provide us with ideal probes of the quark-gluon plasma (QGP) produced in heavy-ion collisions, since its dynamics at its different scales is imprinted into the multi-scale sub…
A New Paradigm for Precision Top Physics: Weighing the Top with Energy Correlators
Jack Holguin, Ian Moult, Aditya Pathak +1
Final states in collider experiments are characterized by correlation functions, , of the energy flow operator . We sh…
Rings and strings: a basis for understanding subleading colour and QCD coherence beyond the two-jet limit
Jeffrey R. Forshaw, Jack Holguin, Simon Plätzer
Guided by the colour-diagonal structure of collinear singularities, we identify a set of kinematic basis functions that are well suited to the simplification of soft gluon emission…
Coulomb gluons will generally destroy coherence
Jeffrey R. Forshaw, Jack Holguin
Coherence violation is an interesting and counter-intuitive phenomenon in QCD. We discuss the circumstances under which violation occurs in observables sensitive to soft radiation…
Ordering multiple soft gluon emissions using Glauber-SCET
Jeffrey Robert Forshaw, Jack Holguin, Aditya Pathak
In QCD, the amplitude for multiple soft gluon emissions has been shown to exhibit a form of coherence, wherein one-loop corrections are rendered IR finite by the transverse momentu…
Improvements on dipole shower colour
Jack Holguin, Jeffrey R. Forshaw, Simon Plätzer
The dipole formalism provides a powerful framework from which parton showers can be constructed. In a recent paper, we proposed a dipole shower with improved colour accuracy and in…
Comments on a new `full colour' parton shower
Jack Holguin, Jeffrey R. Forshaw, Simon Plätzer
A new parton shower algorithm has been presented with the claim of providing soft-gluon resummation at `full colour' (arXiv:2001.11492). In this paper we show that the algorithm do…
Building a consistent parton shower
Jeffrey R. Forshaw, Jack Holguin, Simon Plätzer
Modern parton showers are built using one of two models: dipole showers or angular ordered showers. Both have distinct strengths and weaknesses. Dipole showers correctly account fo…
Parton branching at amplitude level
Jeffrey R. Forshaw, Jack Holguin, Simon Plätzer
We present an algorithm that evolves hard processes at the amplitude level by dressing them iteratively with (massless) quarks and gluons. The algorithm interleaves collinear emiss…
