Virtual QCD corrections to : top-quark loops from a transverse-momentum expansion
Giuseppe Degrassi, Ramona Gröber, Marco Vitti
We present the virtual corrections due to the top-quark loops for the process at next-to-leading order in QCD. The associated two-loop box diagrams are computed using a…
Higgs probes of top contact interactions and their interplay with Higgs self-coupling
Stefano Di Noi, Ramona Gröber
We present a method which relies on loop contributions from four-top SMEFT operators to single Higgs observables to contrain their Wilson coefficients. Such loop-induced terms have…
Higgs boson pair production at NLO in the POWHEG approach and the top quark mass uncertainties
Emanuele Bagnaschi, Giuseppe Degrassi, Ramona Gröber
We present a new Monte Carlo code for Higgs boson pair production at next-to-leading order in the POWHEG-BOX Monte Carlo approach. The code is based on analytic results for the two…
Machine learning the trilinear and light-quark Yukawa couplings from Higgs pair kinematic shapes
Lina Alasfar, Ramona Gröber, Christophe Grojean +2
Revealing the Higgs pair production process is the next big challenge in high energy physics. In this work, we explore the use of interpretable machine learning and cooperative gam…
Light stop decays into near the kinematic threshold
Ramona Grober, Margarete Muhlleitner, Eva Popenda +1
We investigate the decays of the light stop in scenarios with the lightest neutralino being the lightest supersymmetric particle, including flavour-violating (FV) eff…
Les Houches 2013: Physics at TeV Colliders: New Physics Working Group Report
G. Brooijmans, R. Contino, B. Fuks +87
We present the activities of the "New Physics" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 3--21 June, 2013). Our report includes new computatio…
