Cheung, Clifford, Nomura, Yasunori, Thaler, Jesse
Supersymmetric phenomenology has been largely bound to the hypothesis that supersymmetry breaking originates from a single source. In this paper, we relax this underlying assumption and consider a...
Krohn, David, Thaler, Jesse, Wang, Lian-Tao
Initial state radiation, multiple interactions, and event pileup can contaminate jets and degrade event reconstruction. Here we introduce a procedure, jet trimming, designed to mitigate these sources...
Constraining the Axion Portal with B -> K l+ l- (2009)
Freytsis, Marat, Ligeti, Zoltan, Thaler, Jesse
We investigate the bounds on axionlike states from flavor-changing neutral current b->s decays, assuming the axion couples to the standard model through mixing with the Higgs sector. Such GeV-scale...
Supermodels for early LHC (2009)
Bauer, Christian W., Ligeti, Zoltan, Schmaltz, Martin, Thaler, Jesse, Walker, Devin G. E.
We investigate what new physics signatures the LHC can discover in the 2009-2010 run, beyond the expected sensitivity of the Tevatron data by 2010. We construct "supermodels", for which the LHC...
Dark Force Detection in Low Energy e-p Collisions (2009)
Freytsis, Marat, Ovanesyan, Grigory, Thaler, Jesse
We study the prospects for detecting a light boson X with mass m_X < 100 MeV at a low energy electron-proton collider. We focus on the case where X dominantly decays to e+ e- as motivated by recent...
Cosmic Signals from the Hidden Sector (2009)
Mardon, Jeremy, Nomura, Yasunori, Thaler, Jesse
Cosmologically long-lived, composite states arise as natural dark matter candidates in theories with a strongly interacting hidden sector at a scale of 10 - 100 TeV. Light axion-like states, with...
Krohn, David, Thaler, Jesse, Wang, Lian-Tao
We introduce a new class of jet algorithms designed to return conical jets with a variable Delta R radius. A specific example, in which Delta R scales as 1/pT, proves particularly useful in capturing...
Dark Matter Signals from Cascade Annihilations (2009)
Mardon, Jeremy, Nomura, Yasunori, Stolarski, Daniel, Thaler, Jesse
A leading interpretation of the electron/positron excesses seen by PAMELA and ATIC is dark matter annihilation in the galactic halo. Depending on the annihilation channel, the electron/positron...
Collective Quartics and Dangerous Singlets in Little Higgs (2008)
Schmaltz, Martin, Thaler, Jesse
Any extension of the standard model that aims to describe TeV-scale physics without fine-tuning must have a radiatively-stable Higgs potential. In little Higgs theories, radiative stability is...
Dark Matter through the Axion Portal (2008)
Nomura, Yasunori, Thaler, Jesse
Motivated by the galactic positron excess seen by PAMELA and ATIC/PPB-BETS, we propose that dark matter is a TeV-scale particle that annihilates into a pseudoscalar "axion." The positron excess and...
We present a class of composite Higgs models in which the particle that regulates the top quark contribution to the Higgs potential is also a weakly-interacting dark matter candidate. This...
Strategies to Identify Boosted Tops (2008)
We study techniques for identifying highly boosted top jets, where the subsequent top decay products are not isolated. For hadronic boosted tops, we consider variables which probe the jet...
GenEvA (I): A new framework for event generation (2008)
Bauer, Christian W., Tackmann, Frank J., Thaler, Jesse
We show how many contemporary issues in event generation can be recast in terms of partonic calculations with a matching scale. This framework is called GenEvA, and a key ingredient is a new notion...
GenEvA (II): A phase space generator from a reweighted parton shower (2008)
Bauer, Christian W., Tackmann, Frank J., Thaler, Jesse
We introduce a new efficient algorithm for phase space generation. A parton shower is used to distribute events across all of multiplicity, flavor, and phase space, and these events can then be...
Natural Dark Matter from an unnatural Higgs boson and new colored particles at the TeV scale (2007)
The thermal relic abundance of Dark Matter motivates the existence of new electroweak scale particles, independent of naturalness considerations. However, most unnatural Dark Matter models do not...
Probing Minimal Flavor Violation at the LHC (2007)
Grossman, Yuval, Nir, Yosef, Thaler, Jesse, Volansky, Tomer, Zupan, Jure
If the LHC experiments discover new particles that couple to the Standard Model fermions, then measurements by ATLAS and CMS can contribute to our understanding of the flavor puzzles. We demonstrate...
Disentangling dimension six operators through di-Higgs boson production (2007)
Pierce, Aaron, Thaler, Jesse, Wang, Lian-Tao
New physics near the TeV scale can generate dimension-six operators that modify the production rate and branching ratios of the Higgs boson. Here, we show how Higgs boson pair production can yield...
MARMOSET: The Path from LHC Data to the New Standard Model via On-Shell Effective Theories (2007)
Arkani-Hamed, Nima, Knuteson, Bruce, Mrenna, Stephen, Schuster, Philip, Thaler, Jesse, Toro, Natalia, ...
We describe a coherent strategy and set of tools for reconstructing the fundamental theory of the TeV scale from LHC data. We show that On-Shell Effective Theories (OSETs) effectively characterize...
Natural Dark Matter from an Unnatural Higgs Boson and New Colored Particles at the TeV Scale (2007)
The thermal relic abundance of Dark Matter motivates the existence of new electroweak scale particles, independent of naturalness considerations. However, most unnatural Dark Matter models do not...

Pierce, Aaron, Thaler, Jesse, Wang, Lian-Tao
New physics near the TeV scale can generate dimension-six operators that modify the production rate and branching ratios of the Higgs boson. Here, we show how Higgs boson pair production can yield...
Supersymmetry and the LHC inverse problem (2006)
Arkani-Hamed, Nima, Kane, Gordon L., Thaler, Jesse, Wang, Lian-Tao
Given experimental evidence at the LHC for physics beyond the standard model, how can we determine the nature of the underlying theory? We initiate an approach to studying the ``inverse map" from the...
Cheng, Hsin-Chia, Thaler, Jesse, Wang, Lian-Tao
Using the language of theory space, i.e. moose models, we develop a unified framework for studying composite Higgs models at the LHC. This framework--denoted little M-theory--is conveniently...
(Reverse) Engineering Vacuum Alignment (2006)
Cheung, Clifford, Thaler, Jesse
In the presence of spontaneous symmetry breaking, the alignment of the vacuum with respect to the gauge group is often controlled by quadratically divergent operators in the low energy non-linear...
Prospects for Mirage Mediation (2006)
Mirage mediation reduces the fine-tuning in the minimal supersymmetric standard model by dynamically arranging a cancellation between anomaly-mediated and modulus-mediated supersymmetry breaking. We...
Spontaneous Lorentz Breaking at High Energies (2006)
Cheng, Hsin-Chia, Luty, Markus A., Mukohyama, Shinji, Thaler, Jesse
Theories that spontaneously break Lorentz invariance also violate diffeomorphism symmetries, implying the existence of extra degrees of freedom and modifications of gravity. In the minimal model...
Supersymmetry and the LHC Inverse Problem (2005)
Arkani-Hamed, Nima, Kane, Gordon L., Thaler, Jesse, Wang, Lian-Tao
Given experimental evidence at the LHC for physics beyond the standard model, how can we determine the nature of the underlying theory? We initiate an approach to studying the "inverse map" from the...
Neutrino Constraints on Spontaneous Lorentz Violation (2005)
Grossman, Yuval, Kilic, Can, Thaler, Jesse, Walker, Devin G. E.
We study the effect of spontaneous Lorentz violation on neutrinos. We consider two kinds of effects: static effects, where the neutrino acquires a Lorentz-violating dispersion relation, and dynamic...
Inspired by the AdS/CFT correspondence, we show that any G/H symmetry breaking pattern can be described by a simple two-site moose diagram. This construction trivially reproduces the CCWZ...
The Littlest Higgs in Anti-de Sitter Space (2005)
We implement the SU(5)/SO(5) littlest Higgs theory in a slice of 5D Anti-de Sitter space bounded by a UV brane and an IR brane. In this model, there is a bulk SU(5) gauge symmetry that is broken to...
Arkani-Hamed, Nima, Cheng, Hsin-Chia, Luty, Markus, Thaler, Jesse
We study the universal low-energy dynamics associated with the spontaneous breaking of Lorentz invariance down to spatial rotations. The effective Lagrangian for the associated Goldstone field can be...
Dynamics of Black Hole Formation in an Exactly Solvable Model (2002)
We consider the process of black hole formation in particle collisions in the exactly solvable framework of 2+1 dimensional Anti de Sitter gravity. An effective Hamiltonian describing the near...
