Prospects for measuring quark polarization and spin correlations in and samples at the LHC
Yevgeny Kats, David Uzan
Polarization and spin correlations have been studied in detail for top quarks at the LHC, but have been explored very little for the other flavors of quarks. In this paper we consi…
Searching for dark jets with displaced vertices using weakly supervised machine learning
Debjyoti Bardhan, Yevgeny Kats, Noam Wunch
If "dark quarks" from a confining hidden sector are produced at the LHC, they will shower and hadronize to dark sector hadrons, which may decay back to Standard Model particles wit…
Kinked tracks from baryons as a probe of light quark polarizations
Yevgeny Kats
Jets initiated by energetic quarks carry in an obvious way approximate information about the original quark energy and momentum. In a less obvious way, they also carry information…
Cosmology of the Twin Higgs without explicit breaking
Hugues Beauchesne, Yevgeny Kats
The cosmology of the Twin Higgs requires the breaking of the symmetry, but it is still an open question whether this breaking needs to be explicit. In this paper, we…
Reinterpretation of LHC Results for New Physics: Status and Recommendations after Run 2
Waleed Abdallah, Shehu AbdusSalam, Azar Ahmadov +139
We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpret…
Searching for periodic signals in kinematic distributions using continuous wavelet transforms
Hugues Beauchesne, Yevgeny Kats
Many models of physics beyond the Standard Model include towers of particles whose masses follow an approximately periodic pattern with little spacing between them. These resonance…
Clockwork/Linear Dilaton: Structure and phenomenology
Riccardo Torre
I briefly discuss the main phenomenological features and constraints of the Clockwork/Linear Dilaton (CW/LD) 5D geometry. This contribution is based on the work of ref. arXiv:1711.…
Measuring quark polarizations at ATLAS and CMS
Yevgeny Kats
Being able to measure the polarization of quarks produced in various processes at the LHC would be of fundamental significance. Measuring the polarizations of quarks produced in ne…
Clockwork / Linear Dilaton: Structure and Phenomenology
Gian F. Giudice, Yevgeny Kats, Matthew McCullough +2
The linear dilaton geometry in five dimensions, rediscovered recently in the continuum limit of the clockwork model, may offer a solution to the hierarchy problem which is qualitat…
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…
Resonances from QCD bound states and the 750 GeV diphoton excess
Yevgeny Kats, Matthew J. Strassler
Pair production of colored particles is in general accompanied by production of QCD bound states (onia) slightly below the pair-production threshold. Bound state annihilation leads…
Measuring polarizations of bottom, charm, strange, up and down quarks in top decays
Yevgeny Kats
Standard Model samples in ATLAS and CMS provide an opportunity to conduct measurements of the polarization of quarks produced in top-quark decays. The bottom quarks from…
Interpreting a 750 GeV Diphoton Resonance
Rick S. Gupta, Sebastian Jäger, Yevgeny Kats +2
We discuss the implications of the significant excesses in the diphoton final state observed by the LHC experiments ATLAS and CMS around a diphoton invariant mass of 750 GeV. The i…
Measuring c-quark polarization in W+c samples at ATLAS and CMS
Yevgeny Kats
The process produces polarized charm quarks. The polarization is expected to be partly retained in baryons when those form in the -quark hadronization. We ar…
Hadronic Calorimeter Shower Size: Challenges and Opportunities for Jet Substructure in the Superboosted Regime
Shikma Bressler, Thomas Flacke, Yevgeny Kats +2
Hadrons have finite interaction size with dense material, a basic feature common to known forms of hadronic calorimeters (HCAL). We argue that substructure variables cannot use HCA…
Measuring polarization of light quarks at ATLAS and CMS
Yevgeny Kats
Polarization of strange quarks is preserved to a high degree when they hadronize into Lambda baryons, as observed in Z decays at LEP. This opens up the possibility for ATLAS and CM…
Heavy baryons as polarimeters at colliders
Mario Galanti, Andrea Giammanco, Yuval Grossman +3
In new-physics processes that produce b or c jets, a measurement of the initial b or c-quark polarization could provide crucial information about the structure of the new physics.…
Snowmass 2013 Top quark working group report
K. Agashe, R. Erbacher, C. E. Gerber +167
This report summarizes the work of the Energy Frontier Top Quark working group of the 2013 Community Summer Study (Snowmass).
LHC searches examined via the RPV MSSM
Jared A. Evans, Yevgeny Kats
We confront the ATLAS and CMS new physics searches with simplified models from R-parity violating (RPV) supersymmetry that contain naturally light stops and higgsinos. We emphasize…
Toward Full LHC Coverage of Natural Supersymmetry
Jared A. Evans, Yevgeny Kats, David Shih +1
We argue that combining just a handful of searches for new physics at Run I of the LHC is sufficient to exclude most supersymmetric extensions of the Standard Model in which the gl…
LHC Coverage of RPV MSSM with Light Stops
Jared A. Evans, Yevgeny Kats
We examine the sensitivity of recent LHC searches to signatures of supersymmetry with R-parity violation (RPV). Motivated by naturalness of the Higgs potential, which would favor l…
Probing Colored Particles with Photons, Leptons, and Jets
Yevgeny Kats, Matthew J. Strassler
If pairs of new colored particles are produced at the Large Hadron Collider, determining their quantum numbers, and even discovering them, can be non-trivial. We suggest that valua…
The Status of GMSB After 1/fb at the LHC
Yevgeny Kats, Patrick Meade, Matthew Reece +1
We thoroughly investigate the current status of supersymmetry in light of the latest searches at the LHC, using General Gauge Mediation (GGM) as a well-motivated signature generato…
Light Stop NLSPs at the Tevatron and LHC
Yevgeny Kats, David Shih
How light can the stop be given current experimental constraints? Can it still be lighter than the top? In this paper, we study this and related questions in the context of gauge-m…
