I present the resummation of collinear and soft gluon corrections to single top quark production in the t channel at next-to-next-to-leading logarithm (NNLL) accuracy using two-loop soft anomalous dimensions. The expansion of the resummed cross section yields approximate next-to-next-to-leading order (NNLO) cross sections. Numerical results for t-channel single top quark (or single antitop) production at the Tevatron and the LHC are presented, including the dependence of the cross sections on the top quark mass, and the uncertainties from scale variation and parton distributions. Combined results for all single top quark production channels are also given.

  1. Cross-section measurements for the production of a $W$-boson in association with high-transverse-momentum jets in $pp$ collisions at $\sqrt{s}$= 13 TeV with the ATLAS detector

    hep-ex 2024-12 accept novelty 6.0 of 10

    New ATLAS measurements of W+jet production with leading-jet transverse momentum above 500 GeV, including a new collinear phase space, are largely described by NLO multi-leg generators and NNLO MCFM, with MCFM undersho...

  2. Search for flavour-changing neutral currents in processes with one top quark and a photon using 81 fb$^{-1}$ of $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS experiment

    hep-ex 2019-08 accept novelty 6.0 of 10

    ATLAS finds no evidence for tqγ flavour-changing neutral currents and sets the most stringent limits to date on the associated production cross sections and branching ratios.

  3. Search for bottom-squark pair production with the ATLAS detector in final states containing Higgs bosons, $b$-jets and missing transverse momentum

    hep-ex 2019-08 accept novelty 6.0 of 10

    A search for bottom-squark pairs decaying into Higgs bosons, b-quarks, and missing energy found no excess and excluded bottom-squark masses up to 1.5 TeV.

  4. Measurements of top-quark pair differential and double-differential cross-sections in the $\ell$+jets channel with $pp$ collisions at $\sqrt{s}=13$ TeV using the ATLAS detector

    hep-ex 2019-08 accept novelty 5.0 of 10

    ATLAS presents single- and double-differential top-quark pair cross-sections in the l+jets channel at 13 TeV, finding good overall agreement with predictions but tensions in boosted high-pT tails.

  5. Search for non-resonant Higgs boson pair production in the $bb\ell\nu\ell\nu$ final state with the ATLAS detector in $pp$ collisions at $\sqrt{s} = 13$ TeV

    hep-ex 2019-08 accept novelty 5.0 of 10

    With 139 fb^-1 of 13 TeV proton-proton data, ATLAS sets a 95% CL upper limit of 1.2 pb (40 times the Standard Model) on non-resonant Higgs boson pair production in the bbllvv final state.

  6. Constraining dimension-6 SMEFT with higher-order predictions for $p p \to t W$

    hep-ph 2026-01 unverdicted novelty 4.0 of 10

    Higher-order QCD predictions for pp to tW enable three-parameter SMEFT fits that constrain effective new-physics scales to 0.5–2 TeV using LHC Run II and III data.

  7. Search for pair-produced vector-like $T$-quarks decaying into $Ht$ final states in the lepton-plus-jets channel in $pp$ collisions at $\sqrt{s}$=13 TeV with the ATLAS detector

    hep-ex 2026-05 unverdicted novelty 3.0 of 10

    No excess observed in search for vector-like T-quarks in Ht channel; 95% CL mass limits set at 1.40 TeV (SU(2) singlet), 1.56 TeV (doublet), and 1.66 TeV (100% BR to Ht).
