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…
Exorcizing Ghosts from the Vacuum Spectra in String-inspired Nonlocal Tachyon Condensation
Florian Nortier
Tachyon condensation in quantum field theory (QFT) plays a central role in models of fundamental interactions and cosmology. Inspired by tower truncation in string field theory, ul…
The Two Scales of New Physics in Higgs Couplings
Raffaele Tito D'Agnolo, Florian Nortier, Gabriele Rigo +1
Higgs coupling deviations from Standard Model predictions contain information about two scales of Nature: that of new physics responsible for the deviation, and the scale where new…
Fate of the false vacuum in string-inspired nonlocal field theory
Anish Ghoshal, Florian Nortier
In this article, we study Coleman bounce in weakly nonlocal theories which are motivated from string field theory. The kinetic term is extended via an infinite series of high-order…
Extra Dimensions and Fuzzy Branes in String-inspired Nonlocal Field Theory
Florian Nortier
Particle physics models with extra dimensions of space (EDS's) and branes shed new light on electroweak and flavor hierarchies with a rich TeV scale phenomenology. This article hig…
Rigorous treatment of the orbifold model with brane-Higgs couplings
Ruifeng Leng, Grégory Moreau, Florian Nortier
We build rigorously the attractive five-dimensional model where bulk fermions propagate along the orbifold and interact with a Higgs boson localised…
Comment on "Braneworld Effective Field Theories -- Holography, Consistency and Conformal Effects"
Florian Nortier
Several arguments given in arXiv:1912.12316 suggest that braneworld effective models with fields strictly localized on -like branes cannot be UV-completed by a fundamental theor…
Compactified Spacelike Extra Dimension & Brane-Higgs Field
Florian Nortier
In the paradigm with a small warped Spacelike Extra Dimensions (SED), the Higgs field is in general localized at a boundary of the SED (TeV-brane) where the gravity scale is redshi…
Large Star/Rose Extra Dimension with Small Leaves/Petals
Florian Nortier
In this paper, we propose to compactify a single large extra dimension (LED) on a star/rose graph with a large number of identical leaves/petals. The 5D Planck scale can be chosen…
Beyond brane-Higgs regularisation: clarifying the method and model
Andrei Angelescu, Ruifeng Leng, Grégory Moreau +1
The class of higher-dimensional scenarios, based on a brane-localised Higgs boson coupled to bulk fermions, can address both the flavour puzzle and gauge hierarchy problem. A key q…
