Limitations of quantum tomography in Higgs-boson decays to four leptons
Morgan Del Gratta, Fabio Maltoni, Davide Pagani +1
We investigate the limitations of the two-qutrit quantum tomography in Higgs-boson decays to four charged leptons. At next-to-leading order, the standard reconstruction can yield a…
Top-Antitop Production and Decay at Threshold at the LHC in QCD Perturbation Theory
Paolo Nason, Giovanni Pelliccioli, Emanuele Re +1
In this work we consider the production of a top-antitop pair at the LHC when the mass of the pair is relatively near to the nominal threshold, that is to say to twice the top pole…
