Testing parton distribution functions with t-channel single-top-quark production
John Campbell, Tobias Neumann, Zack Sullivan
The production of single top-quarks in the t-channel at hadron colliders imposes strong analytic constraints on parton distribution functions (PDFs) through its double deeply inela…
Single-top-quark production in the -channel at NNLO
John Campbell, Tobias Neumann, Zack Sullivan
We present a calculation of t-channel single-top-quark production and decay in the five-flavor scheme at NNLO. Our results resolve a disagreement between two previous calculations…
Off-shell single-top-quark production in the Standard Model Effective Field Theory
Tobias Neumann, Zack Sullivan
We present a fully differential and spin-dependent -channel single-top-quark calculation at next-to-leading order (NLO) in QCD including off-shell effects by using the complex m…
Are PDFs still consistent with Tevatron data?
Zack Sullivan
As active data taking has moved to the LHC at CERN, more and more LHC data have been included into fits of parton distribution functions. An anomaly has arisen where formerly excel…
Spherical harmonics for multiparticle final states
Keith Pedersen, Zack Sullivan
We examine collider physics via the spectral power H_l, which utilizes much more detector information than sequential jet reconstruction. We use H_l to define a novel jet definitio…
Probing the two Higgs doublet wedge region with charged Higgs boson decays to boosted jets
Keith Pedersen, Zack Sullivan
Two Higgs doublet extensions of the standard model, such as supersymmetry, predict the existence of charged Higgs bosons. We explore the reach for TeV-scale charged Higgs bosons th…
