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-…
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…
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…
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…
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…
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…
Gauge flavour unification: from the flavour puzzle to stable protons
Joe Davighi
The idea of unification attempts to explain the structure of the Standard Model (SM) in terms of fewer fundamental forces and/or matter fields. However, traditional grand unified t…
Flatland: abelian extensions of the Standard Model with semi-simple completions
Joe Davighi, Joseph Tooby-Smith
We parametrise the space of all possible flavour non-universal extensions of the Standard Model that embed inside anomaly-free semi-simple gauge theories, inclu…
Leptoquarks with Exactly Stable Protons
Joe Davighi, Admir Greljo, Anders Eller Thomsen
We explore a novel mechanism to restrict TeV-scale leptoquark interactions and render the proton exactly stable to all orders in the effective field theory expansion. A scalar cond…
Electroweak flavour unification
Joe Davighi, Joseph Tooby-Smith
We propose that the electroweak and flavour quantum numbers of the Standard Model (SM) could be unified at high energies in an anomaly-free gau…
Anomalous bosons for anomalous decays
Joe Davighi
Motivated by the intriguing discrepancies in transitions, the fermion mass problem, and a desire to preserve the accidental symmetries of the Standard Model (SM),…
Global Fits of Third Family Hypercharge Models to Neutral Current B-Anomalies and Electroweak Precision Observables
B. C. Allanach, J. Eliel Camargo-Molina, Joe Davighi
While it is known that third family hypercharge models can explain the neutral current anomalies, it was hitherto unclear whether the mixing predicted by such mode…
Undulating Dark Matter
Joe Davighi, Matthew McCullough, Joseph Tooby-Smith
We suggest that an interplay between microscopic and macroscopic physics can give rise to dark matter (DM) whose interactions with the visible sector fundamentally undulate in time…
