Opening the Topological Portal to Dark Sectors with Colliders
Joe Davighi, Admir Greljo, Lia Schöneweiß +1
We study the phenomenology of the topological portal between QCD and pseudo-Nambu--Goldstone dark matter proposed in~\cite{Davighi:2024zip}. We construct a weakly coupled ultraviol…
Axion Quality from Exact Proton Stability
Joe Davighi, Admir Greljo, Xavier Ponce Díaz
A discrete, anomaly-free gauge symmetry may persist to the deep infrared, exactly forbidding proton decay. This can emerge from Higgsing a lepton-flavou…
A Composite Theory of Higgs and Flavour
Joe Davighi, Gino Isidori
We introduce a composite Higgs model in which a flavour deconstructed gauge group is embedded in the strong sector. The pattern of global symmetry breaking yields, as pseudo-Nambu-…
Bosonisation Cohomology: Spin Structure Summation in Every Dimension
Philip Boyle Smith, Joe Davighi
Gauging fermion parity and summing over spin structures are subtly distinct operations. We introduce 'bosonisation cohomology' groups to capture this difference, for…
Scalar Amplitudes from Fibre Bundle Geometry
Mohammad Alminawi, Ilaria Brivio, Joe Davighi
We compute tree-level -point scattering amplitudes in scalar field theories in terms of geometric invariants on a fibre bundle. All 0- and 2-derivative interactions are incorpor…
ECFA Higgs, electroweak, and top Factory Study
H. Abidi, J. A. Aguilar-Saavedra, S. Airen +373
The ECFA Higgs, electroweak, and top Factory Study ran between 2021 and 2025 as a broad effort across the experimental and theoretical particle physics communities, bringing togeth…
Topological Freeze-out by Semi-Annihilation
Joe Davighi, Serah Moldovsky, Hitoshi Murayama +2
We point out that a QCD-like dark sector can be coupled to the Standard Model by gauging the topological Skyrme current, which measures the dark baryon number in the infrared, to g…
Generalised Symmetries in Particle Physics
Joe Davighi
In this talk I review various notions of generalised global symmetry: higher-form, higher-group, and non-invertible symmetry. All these notions have had profound impact on quantum…
Precision Tests in () at FCC-ee
Marzia Bordone, Claudia Cornella, Joe Davighi
The rare semi-leptonic decays , with , are highly sensitive to new physics (NP) due to their suppression in the Standard Model (SM). Current LH…
Higgs and Flavour: BSM Overview
Joe Davighi
We discuss scenarios for BSM physics near the TeV, motivated by the hierarchy problem and the flavour puzzle, and review their experimental tests at present and future colliders. S…
Fractional Hydrodynamic Transport from the Witten Anomaly
Joe Davighi, Nakarin Lohitsiri, Napat Poovuttikul
We study the physical consequences of 't Hooft anomalies in the high-temperature limit of relativistic quantum field theories with , or more generally , global symm…
In Search of an Invisible
Joe Davighi
We consider extending the Standard Model by an anomaly-free and possibly flavour non-universal gauge symmetry, whose breaking gives a boson that does not affect…
WZW terms without anomalies: generalised symmetries in chiral Lagrangians
Joe Davighi, Nakarin Lohitsiri
We consider a 4d non-linear sigma model on the coset $(\mathrm{SU}(N)_L \times \mathrm{SU}(N)_R \times \mathrm{SU}(2))/(\mathrm{SU}(N)_{L+R}\times \mathrm{U}(1))\cong \mathrm{SU}(N…
Flavour Deconstructing the Composite Higgs
Sebastiano Covone, Joe Davighi, Gino Isidori +1
We present a flavour non-universal extension of the Standard Model combined with the idea of Higgs compositeness. At the TeV scale, the gauge groups and are…
Topological Portal to the Dark Sector
Joe Davighi, Admir Greljo, Nudzeim Selimovic
We propose a unique topological portal between quantum chromodynamics (QCD) and a dark sector characterized by a global symmetry breaking, which connects three QCD to two dark pion…
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…
The Rumble in the Meson: a leptoquark versus a to fit anomalies including 2022 LHCb measurements
Ben Allanach, Joe Davighi
We juxtapose global fits of two bottom-up models (an scalar leptoquark model and a model) of \bsll\ anomalies to flavour data in order to quantify stat…
