Energy flow polynomials: A complete linear basis for jet substructure
Patrick T. Komiske, Eric M. Metodiev, Jesse Thaler
We introduce the energy flow polynomials: a complete set of jet substructure observables which form a discrete linear basis for all infrared- and collinear-safe observables. Energy…
The importance of calorimetry for highly-boosted jet substructure
Evan Coleman, Marat Freytsis, Andreas Hinzmann +4
Jet substructure techniques are playing an essential role in exploring the TeV scale at the Large Hadron Collider (LHC), since they facilitate the efficient reconstruction and iden…
Classification without labels: Learning from mixed samples in high energy physics
Eric M. Metodiev, Benjamin Nachman, Jesse Thaler
Modern machine learning techniques can be used to construct powerful models for difficult collider physics problems. In many applications, however, these models are trained on impe…
US Cosmic Visions: New Ideas in Dark Matter 2017: Community Report
Marco Battaglieri, Alberto Belloni, Aaron Chou +248
This white paper summarizes the workshop "U.S. Cosmic Visions: New Ideas in Dark Matter" held at University of Maryland on March 23-25, 2017.
Generalized Fragmentation Functions for Fractal Jet Observables
Benjamin T. Elder, Massimiliano Procura, Jesse Thaler +2
We introduce a broad class of fractal jet observables that recursively probe the collective properties of hadrons produced in jet fragmentation. To describe these collinear-unsafe…
Disentangling Heavy Flavor at Colliders
Philip Ilten, Nicholas L. Rodd, Jesse Thaler +1
We propose two new analysis strategies for studying charm and beauty quarks at colliders. The first strategy is aimed at testing the kinematics of heavy-flavor quarks within an ide…
Casimir Meets Poisson: Improved Quark/Gluon Discrimination with Counting Observables
Christopher Frye, Andrew J. Larkoski, Jesse Thaler +1
Charged track multiplicity is among the most powerful observables for discriminating quark- from gluon-initiated jets. Despite its utility, it is not infrared and collinear (IRC) s…
Jet Substructure Studies with CMS Open Data
Aashish Tripathee, Wei Xue, Andrew Larkoski +2
We use public data from the CMS experiment to study the 2-prong substructure of jets. The CMS Open Data is based on 31.8/pb of 7 TeV proton-proton collisions recorded at the Large…
Exposing the QCD Splitting Function with CMS Open Data
Andrew Larkoski, Simone Marzani, Jesse Thaler +2
The splitting function is a universal property of quantum chromodynamics (QCD) which describes how energy is shared between partons. Despite its ubiquitous appearance in many QCD c…
Systematics of quark/gluon tagging
Philippe Gras, Stefan Höche, Deepak Kar +7
By measuring the substructure of a jet, one can assign it a "quark" or "gluon" tag. In the eikonal (double-logarithmic) limit, quark/gluon discrimination is determined solely by th…
Colorful Twisted Top Partners and Partnerium at the LHC
Yevgeny Kats, Matthew McCullough, Gilad Perez +2
In scenarios that stabilize the electroweak scale, the top quark is typically accompanied by partner particles. In this work, we demonstrate how extended stabilizing symmetries can…
