Light scalars in light of UV/IR mixing: classicalization via synergy between Vainshtein and chameleon screenings
Florian Nortier
Effective field theories featuring light scalar fields play a pivotal role in addressing fundamental questions in (astro)particle physics and cosmology. However, such theories ofte…

The Two Scales of New Physics in Loop-Induced Higgs Couplings
Florian Nortier, Gabriele Rigo, Pablo Sesma
Probing new physics through precise measurements of Higgs boson couplings is a central objective of the particle collider program at the high-energy frontier. An anomaly in Higgs c…

Ghost-free Electroweak Symmetry Breaking with Weakly Nonlocal Interactions
Pratik Chattopadhyay, Florian Nortier
Weakly nonlocal (WNL) Quantum Field Theories (QFT's) may define a new class of UV-completions in particle physics and gravity, without introducing any new elementary particle. One…
