On Statistical Aspects of Qjets
Stephen D. Ellis, Andrew Hornig, David Krohn +1
The process by which jet algorithms construct jets and subjets is inherently ambiguous and equally well motivated algorithms often return very different answers. The Qjets procedur…
Quantifying the power of multiple event interpretations
Yang-Ting Chien, David Farhi, David Krohn +3
A number of methods have been proposed recently which exploit multiple highly-correlated interpretations of events, or of jets within an event. For example, Qjets reclusters a jet…
Jet Cleansing: Pileup Removal at High Luminosity
David Krohn, Matthew Low, Matthew D. Schwartz +1
One of the greatest impediments to extracting useful information from high luminosity hadron-collider data is radiation from secondary collisions (i.e. pileup) which can overlap wi…
Jet Sampling: Improving Event Reconstruction through Multiple Interpretations
Dilani Kahawala, David Krohn, Matthew D. Schwartz
The classification of events involving jets as signal-like or background-like can depend strongly on the jet algorithm used and its parameters. This is partly due to the fact that…
Jet Charge at the LHC
David Krohn, Tongyan Lin, Matthew D. Schwartz +1
Knowing the charge of the parton initiating a light-quark jet could be extremely useful both for testing aspects of the Standard Model and for characterizing potential beyond-the-S…
Qjets: A Non-Deterministic Approach to Tree-Based Jet Substructure
Stephen D. Ellis, Andrew Hornig, David Krohn +2
Jet substructure is typically studied using clustering algorithms, such as kT, which arrange the jets' constituents into trees. Instead of considering a single tree per jet, we pro…
Jet Substructure at the Tevatron and LHC: New results, new tools, new benchmarks
A. Altheimer, S. Arora, L. Asquith +68
In this report we review recent theoretical progress and the latest experimental results in jet substructure from the Tevatron and the LHC. We review the status of and outlook for…
Measuring the Bottom-Quark Forward-Central Asymmetry at the LHC
Dilani Kahawala, David Krohn, Matthew J. Strassler
Measurements of the top quark forward-backward asymmetry performed at the Tevatron suggest that new-physics may be playing a role in t-tbar production. To better understand the sou…
A Higgsophilic s-channel Z' and the CDF W+2J Anomaly
JiJi Fan, David Krohn, Paul Langacker +1
The CDF collaboration recently presented evidence for an excess in the dijet invariant mass distribution coming from events in a W+2j exclusive sample. Here we show that this exces…
Simplified Models for LHC New Physics Searches
Daniele Alves, Nima Arkani-Hamed, Sanjay Arora +92
This document proposes a collection of simplified models relevant to the design of new-physics searches at the LHC and the characterization of their results. Both ATLAS and CMS hav…
A Polarized View of the Top Asymmetry
David Krohn, Tao Liu, Jessie Shelton +1
Recent experimental results from the CDF collaboration which study the top forward-backward asymmetry have strengthened the case that new physics is playing a role in t-tbar produc…
Heavy Squarks at the LHC
JiJi Fan, David Krohn, Pablo Mosteiro +2
The LHC, with its seven-fold increase in energy over the Tevatron, is capable of probing regions of SUSY parameter space exhibiting qualitatively new collider phenomenology. Here w…
On the Feasibility and Utility of ISR Tagging
David Krohn, Lisa Randall, Lian-Tao Wang
The production of new particles at a hadron collider like the LHC is always accompanied by QCD radiation attributable to the initial state (i.e. ISR). This tends to complicate anal…
Boosted objects: a probe of beyond the Standard Model physics
A. Abdesselam, E. Bergeaas Kuutmann, U. Bitenc +59
We present the report of the hadronic working group of the BOOST2010 workshop held at the University of Oxford in June 2010. The first part contains a review of the potential of ha…
Unburied Higgs
Adam Falkowski, David Krohn, Jessie Shelton +2
Many models of physics beyond the Standard Model yield exotic Higgs decays. Some of these, particularly those in which the Higgs decays to light quarks or gluons, can be very diffi…
Semielastic Dark Matter
David Krohn, Joshua T. Ruderman, Lian-Tao Wang
Many models have recently been proposed in which dark matter (DM) couples to Standard Model fields via a GeV-scale dark sector. We consider scenarios of this type where the DM mass…
Jet Trimming
David Krohn, Jesse Thaler, Lian-Tao Wang
Initial state radiation, multiple interactions, and event pileup can contaminate jets and degrade event reconstruction. Here we introduce a procedure, jet trimming, designed to mit…
New Physics Signals in Longitudinal Gauge Boson Scattering at the LHC
Tao Han, David Krohn, Lian-Tao Wang +1
We introduce a novel technique designed to look for signatures of new physics in vector boson fusion processes at the TeV scale. This functions by measuring the polarization of the…
Measuring the Polarization of Boosted Hadronic Tops
David Krohn, Jessie Shelton, Lian-Tao Wang
We propose a new technique for measuring the polarization of hadronically decaying boosted top quarks. In particular, we apply a subjet-based technique to events where the decay pr…
Anomalies in Fermionic UV Completions of Little Higgs Models
David Krohn, Itay Yavin
We consider fermionic UV completions of little Higgs models and their associated T-parity violating anomalous vertices. In particular, we investigate strategies to avoid such parit…
