Asymmetric Dark Matter in Extended Exo-Higgs Scenarios
Hooman Davoudiasl, Pier Paolo Giardino, Cen Zhang
The exo-Higgs model can accommodate a successful baryogenesis mechanism that closely mirrors electroweak baryogenesis in the Standard Model, but avoids its shortcomings. We extend…
NLO predictions for SMEFT in the top-quark sector
Cen Zhang
Predictions for the Standard Model Effective Field Theory at the next-to-leading order accuracy in QCD, including parton-shower effects, have started to become available in the Mad…
Higgs production in association with a top-antitop pair in the Standard Model Effective Field Theory at NLO in QCD
Fabio Maltoni, Eleni Vryonidou, Cen Zhang
We present the results of the computation of the next-to-leading order QCD corrections to the production cross section of a Higgs boson in association with a top-antitop pair at th…
Exo-Higgs at 750 GeV and Genesis of Baryons
Hooman Davoudiasl, Pier Paolo Giardino, Cen Zhang
We propose that the diphoton excess at 750 GeV reported by ATLAS and CMS is due to the decay of an scalar associated with the breaking of a new symm…
Probing top quark neutral couplings in the Standard Model Effective Field Theory at NLO QCD
Olga Bessidskaia Bylund, Fabio Maltoni, Ioannis Tsinikos +2
Top quark pair production in association with a -boson or a photon at the LHC directly probes neutral top-quark couplings. We present predictions for these two processes in the…
Automating Predictions for Standard Model Effective Field Theory in MadGraph5_aMC@NLO
Cen Zhang
Next-to-leading order event generation for the Standard Model effective field theory has started to become available in the MadGraph5_aMC@NLO framework. In this talk we discuss som…
A 750 GeV Messenger of Dark Conformal Symmetry Breaking
Hooman Davoudiasl, Cen Zhang
The tentative hints for a diphoton resonance at a mass of GeV from the ATLAS and CMS experiments at the LHC may be interpreted as first contact with a "dark" sector with…
Single Top Production at Next-to-Leading Order in the Standard Model Effective Field Theory
Cen Zhang
Single top production processes at hadron colliders provide information on the relation between the top quark and the electroweak sector of the standard model. We compute the next-…
