A New Twist on Top Quark Spin Correlations

Matthew Baumgart, Brock Tweedie

Top-antitop pairs produced at hadron colliders are largely unpolarized, but their spins are highly correlated. The structure of these correlations varies significantly over top pro…

Cornering Light Stops with Dileptonic mT2

Can Kilic, Brock Tweedie

Supersymmetric spectra with a stop NLSP and a neutralino or gravitino LSP present a special challenge for collider searches. For stop pairs directly produced from QCD, the visible…

Boosting Searches for Natural SUSY with RPV via Gluino Cascades

Zhenyu Han, Andrey Katz, Minho Son +1

In the presence of even minuscule baryonic R-parity violation, the stop can be the lightest superpartner and evade LHC searches because it decays into two jets. In order to cover t…

Light axigluon explanation of the Tevatron ttbar asymmetry and multijet signals at the LHC

Christian Gross, Gustavo Marques Tavares, Martin Schmaltz +1

The ttbar asymmetry measured at the Tevatron continues to disagree with Standard Model predictions at the 3 sigma level. We update the status of the phenomenological light axigluon…

Testing the Technicolor Interpretation of the CDF Dijet Excess at the 8-TeV LHC

Estia Eichten, Kenneth Lane, Adam Martin +1

Under the assumption that the dijet excess seen by the CDF Collaboration near 150 Gev in Wjj production is due to the lightest technipion of the low-scale technicolor process $ρ_T…

Diboson-Jets and the Search for Resonant Zh Production

Minho Son, Christian Spethmann, Brock Tweedie

New particles at the TeV-scale may have sizeable decay rates into boosted Higgs bosons or other heavy scalars. Here, we investigate the possibility of identifying such processes wh…

The Effective Field Theory of Dark Matter Direct Detection

A. Liam Fitzpatrick, Wick Haxton, Emanuel Katz +2

We extend and explore the general non-relativistic effective theory of dark matter (DM) direct detection. We describe the basic non-relativistic building blocks of operators and di…

Diffractive Higgs Production by AdS Pomeron Fusion

Richard C. Brower, Marko Djurić, Chung-I Tan

The double diffractive Higgs production at central rapidity is formulated in terms of the fusion of two AdS gravitons/Pomerons first introduced by Brower, Polchinski, Strassler and…

Singular ways to search for the Higgs boson

A. De Rújula, A. Galindo

The discovery or exclusion of the fundamental standard scalar is a hot topic, given the data of LEP, the Tevatron and the LHC, as well as the advanced status of the pertinent theor…

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…
