Phenomenology of a Deconstructed Electroweak Force
Joe Davighi, Alastair Gosnay, David J Miller +1
We study an effective theory of flavour in which the interaction is `flavour-deconstructed' near the TeV scale. This arises, for example, in UV models that unify all thre…
A Non-Perturbative Mixed Anomaly and Fractional Hydrodynamic Transport
Joe Davighi, Nakarin Lohitsiri, Napat Poovuttikul
We present a new non-perturbative 't Hooft anomaly afflicting a quantum field theory with symmetry group in four dimensions. We use the Adams spectral s…
Jet Bundle Geometry of Scalar Field Theories
Mohammad Alminawi, Ilaria Brivio, Joe Davighi
For scalar field theories, such as those EFTs describing the Higgs, it is well-known that the 2-derivative Lagrangian is captured by geometry. That is, the set of operators with ex…
Positivity and the Electroweak Hierarchy
Joe Davighi, Scott Melville, Ken Mimasu +1
We point out that an unnatural hierarchy between certain higher-dimensional operator coefficients in a low-energy Effective Field Theory (EFT) would automatically imply that the Hi…
Deconstructed Hypercharge: A Natural Model of Flavour
Joe Davighi, Ben A. Stefanek
The flavour puzzle is one of the greatest mysteries in particle physics. A `flavour deconstruction' of the electroweak gauge symmetry, by promoting at least part of it to the produ…
Non-universal gauge interactions addressing the inescapable link between Higgs and Flavour
Joe Davighi, Gino Isidori
We systematically explore ultraviolet complete models where flavour hierarchies emerge, via approximate accidental symmetries, from an underlying flavour non-universal gauge struct…
Toric 2-group anomalies via cobordism
Joe Davighi, Nakarin Lohitsiri
2-group symmetries arise in physics when a 0-form symmetry and a 1-form symmetry intertwine, forming a generalised group-like structure. Specialising to the cas…
Electroweak-flavour and quark-lepton unification: a family non-universal path
Joe Davighi, Gino Isidori, Marko Pesut
We present a family-non-universal extension of the Standard Model where the the first two families feature both quark-lepton and electroweak-flavour unification, via the $SU(4) \ti…
