Factorization for the light-jet mass and hemisphere soft function (2016)
Journal Article
Becher, T., Pecjak, B. D., & Shao, D. Y. (2016). Factorization for the light-jet mass and hemisphere soft function. Journal of High Energy Physics, 2016(12), Article 18. https://doi.org/10.1007/jhep12%282016%29018

Many collider observables suffer from non-global logarithms not captured by standard resummation techniques. Classic examples are the light-jet mass event shape in the limit of small mass and the related hemisphere soft function. We derive factorizat...

QCD radiative corrections for h→bb¯ in the standard model dimension-6 effective field theory (2016)
Journal Article
Gauld, R., Pecjak, B., & Scott, D. (2016). QCD radiative corrections for h→bb¯ in the standard model dimension-6 effective field theory. Physical Review D, 94(7), Article 074045. https://doi.org/10.1103/physrevd.94.074045

We calculate the O(αs) QCD corrections to the inclusive h→bb¯ decay rate in the dimension-6 standard model effective field theory (SMEFT). The QCD corrections multiplying the dimension-6 Wilson coefficients which alter the hbb¯-vertex at tree-level a...

Associated production of a top pair and a W boson at next-to-next-to-leading logarithmic accuracy (2016)
Journal Article
Broggio, A., Ferroglia, A., Ossola, G., & Pecjak, B. (2016). Associated production of a top pair and a W boson at next-to-next-to-leading logarithmic accuracy. Journal of High Energy Physics, 2016(09), Article 089. https://doi.org/10.1007/jhep09%282016%29089

We consider soft gluon emission corrections to the production of a top-antitop pair in association with a W boson at the Large Hadron Collider. We obtain a soft-gluon resummation formula for this production process which is valid up to next-to-next-t...

Resummed differential cross sections for top-quark pairs at the LHC (2016)
Journal Article
Pecjak, B. D., Scott, D. J., Wang, X., & Yang, L. L. (2016). Resummed differential cross sections for top-quark pairs at the LHC. Physical Review Letters, 116(20), Article 202001. https://doi.org/10.1103/physrevlett.116.202001

We present state of the art resummation predictions for differential cross sections in top-quark pair production at the LHC. They are derived from a formalism which allows the simultaneous resummation of both soft and small-mass logarithms, which end...

One-loop corrections to h → bb¯ and h → ττ¯ decays in the Standard Model dimension-6 EFT: four-fermion operators and the large-m t limit (2016)
Journal Article

We calculate a set of one-loop corrections to h → bb¯¯bb¯ and h → ττ¯¯¯ττ¯ decays in the dimension-6 Standard Model effective field theory (SMEFT). In particular, working in the limit of vanishing gauge couplings, we calculate directly in the broken...

We consider soft gluon emission corrections to the production of a top-antitop pair in association with a Higgs boson at hadron colliders. In particular, we present a soft-gluon resummation formula for this production process and gather all elements... Read More about Associated production of a top pair and a Higgs boson beyond NLO.
