  • Thaler, Jesse; Larkoski, Andrew James (American Physical Society, 2014-08)
    We present three case studies at a 100 TeV proton collider for how jet analyses can be improved using new jet (sub)structure techniques. First, we use the winner-take-all recombination scheme to define a recoil-free jet ...
  • Thaler, Jesse; Kahn, Yonatan Frederick; McCullough, Matthew Philip (Springer-Verlag, 2013-11)
    The discovery of a standard-model-like Higgs at 126 GeV and the absence of squark signals thus far at the LHC both point towards a mini-split spectrum for supersymmetry. Within standard paradigms, it is non-trivial to ...
  • Schmaltz, Martin; Stolarski, Daniel; Thaler, Jesse (Springer Berlin / Heidelberg, 2010-09)
    While little Higgs models provide an interesting way to address the hierarchy problem, concrete models in the literature typically face two major obstacles. First, the mechanism for generating a Higgs quartic coupling ...
  • Mateu Barreda, Vicent; Stewart, Iain; Thaler, Jesse (Springer-Verlag, 2014-03)
    This report of the BOOST2012 workshop presents the results of four working groups that studied key aspects of jet substructure. We discuss the potential of first-principle QCD calculations to yield a precise description ...
  • Chang, Hsi-Ming; Procura, Massimiliano; Thaler, Jesse; Waalewijn, Wouter J. (American Physical Society, 2013-09)
    By using observables that only depend on charged particles (tracks), one can efficiently suppress pileup contamination at the LHC. Such measurements are not infrared safe in perturbation theory, so any calculation of ...
  • Chang, Hsi-Ming; Procura, Massimiliano; Thaler, Jesse; Waalewijn, Wouter J. (American Physical Society, 2013-08)
    In e[superscript +]e[superscript -] event shapes studies at LEP, two different measurements were sometimes performed: a “calorimetric” measurement using both charged and neutral particles and a “track-based” measurement ...
  • Krnjaic, Gordan; Thaler, Jesse; Toups, Matthew; Kahn, Yonatan Frederick (American Physical Society, 2015-03)
    Among laboratory probes of dark matter, fixed-target neutrino experiments are particularly well suited to search for light weakly coupled dark sectors. In this paper, we show that the DAEδALUS source setup—an 800 MeV proton ...
  • D'Eramo, Francesco; Fei, Lin; Thaler, Jesse (IOP Publishing, 2012-03)
    Pure singlets are typically disfavored as dark matter candidates, since they generically have a thermal relic abundance larger than the observed value. In this paper, we propose a new dark matter mechanism called "assimilation", ...
  • Fan, JiJi; Thaler, Jesse; Wang, Lian-Tao (Springer Berlin / Heidelberg, 2010-06)
    We consider explicit models of dynamical supersymmetry breaking where dark matter is a 10 – 100 TeV strongly-interacting composite state carrying no standard model quantum numbers. These constructions are simple variants ...
  • Cheung, Clifford; Mardon, Jeremy; Nomura, Yasunori; Thaler, Jesse (Springer / SISSA, 2010-07)
    If the lightest observable-sector supersymmetric particle (LOSP) is charged and long-lived, then it may be possible to indirectly measure the Planck mass at the LHC and provide a spectacular confirmation of supergravity ...
  • Salam, Gavin P.; Thaler, Jesse; Larkoski, Andrew James (Springer-Verlag, 2013-06)
    We show how generalized energy correlation functions can be used as a powerful probe of jet substructure. These correlation functions are based on the energies and pair-wise angles of particles within a jet, with (N + 1)-point ...
  • Kearney, John; Pierce, Aaron; Thaler, Jesse (Springer-Verlag, 2013-10)
    Little Higgs models often give rise to top partners beyond the minimal ones necessary for the cancellation of quadratic divergences. We review how this occurs and discuss the phenomenology of these exotic states. We emphasize ...
  • Craig, Nathaniel; Stolarski, Daniel; Thaler, Jesse (Springer-Verlag, 2011-11)
    We introduce a novel composite Higgs theory based on con ning supersymmetric QCD. Supersymmetric duality plays a key role in this construction, with a "fat" Higgs boson emerging as a dual magnetic degree of freedom charged ...
  • Bertolini, Daniele; Thaler, Jesse; Walsh, Jonathan R. (Springer-Verlag, 2015-05)
    In collider physics, jet algorithms are a ubiquitous tool for clustering particles into discrete jet objects. Event shapes offer an alternative way to characterize jets, and one can define a jet multiplicity event shape, ...
  • Craig, Nathaniel; McCullough, Matthew Philip; Thaler, Jesse (Springer-Verlag, 2012-06)
    If supersymmetry (SUSY) solves the hierarchy problem, then naturalness considerations coupled with recent LHC bounds require non-trivial superpartner flavor structures. Such “Natural SUSY” models exhibit a large mass ...
  • Thaler, Jesse; Waalewijn, Wouter J.; Larkoski, Andrew James (Springer-Verlag, 2014-11)
    Discriminating quark jets from gluon jets is an important but challenging problem in jet substructure. In this paper, we use the concept of mutual information to illuminate the physics of quark/gluon tagging. Ideal quark/gluon ...
  • Goldstini 
    Cheung, Clifford; Nomura, Yasunori; Thaler, Jesse (Springer Berlin / Heidelberg, 2010-03)
    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 multiplicity of sectors ...
  • Thaler, Jesse; Thomas, Zachary Talbott (Springer Berlin/Heidelberg, 2011-07)
    Supersymmetric collider phenomenology depends crucially on whether the lightest observable-sector supersymmetric particle (LOSP) decays, and if so, what the LOSP decay products are. For instance, in SUSY models where the ...
  • Thaler, Jesse; Van Tilburg, Ken (Springer-Verlag, 2011-03)
    We introduce a new jet shape—N-subjettiness—designed to identify boosted hadronically-decaying objects like electroweak bosons and top quarks. Combined with a jet invariant mass cut, N-subjettiness is an effective ...
  • Bertolini, Daniele; Chan, Tucker R.; Thaler, Jesse (Springer-Verlag Berlin Heidelberg, 2014-04)
    We introduce a new class of event shapes to characterize the jet-like structure of an event. Like traditional event shapes, our observables are infrared/collinear safe and involve a sum over all hadrons in an event, but ...
