The Fermionic Universal One-Loop Effective Action / Ellis, Sebastian A.R. ; Quevillon, Jérémie ; Vuong, Pham Ngoc Hoa ; You, Tevong ; Zhang, Zhengkang
Recent development of path integral matching techniques based on the covariant derivative expansion has made manifest a universal structure of one-loop effective Lagrangians. [...]

NLO QCD+EW predictions for $tHj$ and $tZj$ production at the LHC / Pagani, Davide ; Tsinikos, Ioannis ; Vryonidou, Eleni
In this work we calculate the cross sections for the hadroproduction of a single top quark or antiquark in association with a Higgs ($tHj$) or $Z$ boson ($tZj$) at NLO QCD+EW accuracy. [...]

Universal scattering laws for bouncing cosmology / Le Floch, Bruno (ENS, Paris, IPM) ; LeFloch, Philippe G. (LJLL, Paris) ; Veneziano, Gabriele (CERN)
Many variants of the standard model of cosmology have been proposed where the Big Bang is replaced by a Big Bounce thanks to corrections to Einstein gravity at small scales. [...]
