Partial-Wave Unitarity Bounds on Higher-Dimensional Operators from 2-to- Scattering
Céline Degrande, Hao-Lin Li, Ling-Xiao Xu
We present a systematic method for deriving partial-wave unitarity bounds on Wilson coefficients of higher-dimensional operators in effective field theories involving more than fou…
Collider sensitivity to SMEFT heavy-quark operators at one-loop in top-quark processes
Celine Degrande, Rogerio Rosenfeld, Andres Vasquez
We study the effects of four-heavy-quark operators in the production of top quarks in the framework of the Standard Model Effective Field Theory (SMEFT) at the LHC. In particular,…
Searching for Dark Matter with circularly polarised photons from the Galactic Centre
Marina Cermeño, Céline Degrande, Luca Mantani
Conventional indirect dark matter (DM) searches look for an excess in the electromagnetic emission from the sky that cannot be attributed to known astrophysical sources, but its po…
Global fit of pseudo-Nambu-Goldstone Dark Matter
Chiara Arina, Ankit Beniwal, Céline Degrande +2
We perform a global fit within the pseudo-Nambu-Goldstone dark matter (DM) model emerging from an additional complex scalar singlet with a softly broken global U(1) symmetry. Leadi…
Proposal for the validation of Monte Carlo implementations of the standard model effective field theory
Gauthier Durieux, Ilaria Brivio, Fabio Maltoni +38
We propose a procedure to cross-validate Monte Carlo implementations of the standard model effective field theory. It is based on the numerical comparison of squared amplitudes com…
Can New Physics hide inside the proton?
Stefano Carrazza, Celine Degrande, Shayan Iranipour +2
Modern global analyses of the structure of the proton include collider measurements which probe energies well above the electroweak scale. While these provide powerful constraints…
