Identification of High-Momentum Top Quarks, Higgs Bosons, and W and Z Bosons Using Boosted Event Shapes
/ Conway, J.S. (UC, Davis) ; Bhaskar, R. (UC, Davis) ; Erbacher, R.D. (UC, Davis ; UC, Davis) ; Pilot, J. (UC, Davis ; UC, Davis)
At the Large Hadron Collider, numerous physics processes expected within the standard model and theories beyond it give rise to very high momentum particles decaying to multihadronic final states. Development of algorithms for efficient identification of such "boosted" particles while rejecting the background from multihadron jets from light quarks and gluons can greatly aid in the sensitivity of measurements and new particle searches.

Jet Substructure at the Large Hadron Collider
/ Kogler, Roman (Hamburg U.) ; Nachman, Benjamin (LBNL, Berkeley) ; Schmidt, Alexander (RWTH Aachen U.) ; Asquith, Lily (U. Sussex (main)) ; Campanelli, Mario (U. Coll. London) ; Delitzsch, Chris (Arizona U. (main)) ; Harris, Philip (MIT) ; Hinzmann, Andreas (Hamburg U.) ; Kar, Deepak (Witwatersrand U.) ; McLean, Christine (UC, Davis) et al.
Jet substructure has emerged to play a central role at the Large Hadron Collider, where it has provided numerous innovative ways to search for new physics and to probe the Standard Model, particularly in extreme regions of phase space. In this article we focus on a review of the development and use of state-of-the-art jet substructure techniques by the ATLAS and CMS experiments..

Solving Scattering in N=4 Super-Yang-Mills Theory
/ Arkani-Hamed, Nima (Princeton, Inst. Advanced Study) ; Dixon, Lance J. (SLAC) ; McLeod, Andrew J. (CERN ; UCLA) ; Spradlin, Marcus (Brown U.) ; Trnka, Jaroslav (UC, Davis, QMAP) ; Volovich, Anastasia (Brown U.)
As part of the Snowmass community planning exercise, we highlight an ongoing program of research into the structure of scattering amplitudes in $N$ = 4 super-Yang-Mills theory, particularly in the planar limit of a large number of colors. [...]

The Snowmass Points and Slopes : Benchmarks for SUSY Searches
/ Allanach, B.C. (CERN) ; Battaglia, M. (CERN) ; Blair, G.A. (JAI, UK) ; Carena, M. (Fermilab) ; Roeck, A.De (CERN) ; Dedes, A. (Bonn U.) ; Djouadi, A. (Montpellier U.) ; Gerdes, D. (Michigan U., MCTP) ; Ghodbane, N. (DESY) ; Gunion, J. (UC, Davis) et al.
The ``Snowmass Points and Slopes'' (SPS) are a set of benchmark points and parameter lines in the MSSM parameter space corresponding to different scenarios in the search for Supersymmetry at present and future experiments. This set of benchmarks was agreed upon at the 2001 ``Snowmass Workshop on the Future of Particle Physics'' as a consensus based on different existing proposals..

Strongly Coupled Quintessence
/ D'Amico, Guido (CERN) ; Kaloper, Nemanja (UC, Davis) ; Lawrence, Albion (Brandeis U.)
We present a family of consistent quantum field theories of monodromy quintessence in strong coupling, which can serve as benchmarks in modeling dark energy different from cosmological constant. These theories have discrete gauge symmetries which can protect them from quantum field theory and quantum gravity corrections, both perturbative and nonperturbative. [...]

Performance of Jet Substructure Techniques and Boosted Object Identification in ATLAS
/ Lacey, J
ATLAS has implemented and commissioned many new jet substructure techniques to aid in the identification and interpretation of hadronic final states originating from Lorentz-boosted heavy particles produced at the LHC. These techniques include quantum jets, jet charge, jet shapes, quark/gluon, boosted boson and top quark tagging, along with grooming methods such as pruning, trimming, and filtering. [...]

Interaction networks for the identification of boosted $H\to b\overline{b}$ decays
/ Moreno, Eric A. (Caltech) ; Nguyen, Thong Q. (Caltech) ; Vlimant, Jean-Roch (Caltech) ; Cerri, Olmo (Caltech) ; Newman, Harvey B. (Caltech) ; Periwal, Avikar (Caltech) ; Spiropulu, Maria (Caltech) ; Duarte, Javier M. (UC, San Diego (main) ; Fermilab) ; Pierini, Maurizio (CERN)
We develop an algorithm based on an interaction network to identify high-transverse-momentum Higgs bosons decaying to bottom quark-antiquark pairs and distinguish them from ordinary jets that reflect the configurations of quarks and gluons at short distances. The algorithm's inputs are features of the reconstructed charged particles in a jet and the secondary vertices associated with them. [...]
