Cardinal Composition

open access: yesErkenntnis, 2022
AbstractThe thesis of Weak Unrestricted Composition says that every pair of objects has a fusion. This thesis has been argued by Contessa (Analysis 72(3):455–457, 2012) and Smith (Erkenntnis 84(1):41–55, 2019) to be compatible with the world being junky and hence to evade an argument against the necessity of Strong Unrestricted Composition proposed by ...

Weinberg’s Compositeness

open access: yesSymmetry, 2022
Nearly 60 years ago, Weinberg suggested a criterion for particle “compositeness”, which has acquired a new life with the discovery of new, exotic hadrons. His idea resonates with model-based intuition. I discuss the role it plays in the context of another of Weinberg’s creations, the model-independent framework of effective field theories.

Real and complex fundamental partial compositeness

open access: yesJournal of High Energy Physics, 2020
We complete the analysis of the effective field theory at the electroweak scale for minimal models of fundamental partial compositeness. Specifically, we consider fermions in the complex and real representation of the gauge group underlying the composite

The other effective fermion compositeness

open access: yesJournal of High Energy Physics, 2017
We discuss the only two viable realizations of fermion compositeness described by a calculable relativistic effective field theory consistent with unitarity, crossing symmetry and analyticity: chiral-compositeness vs goldstino-compositeness. We construct

Testing the mechanism of lepton compositeness

open access: yesSciPost Physics, 2021
Strict gauge invariance requires that physical left-handed leptons are actually bound states of the elementary left-handed lepton doublet and the Higgs field within the standard model. That they nonetheless behave almost like pure elementary particles

Counting Composites [PDF]

open access: yesAustralasian Journal of Philosophy, 2021
I defend the thesis that Composition Entails Identity (CEI): that is, a whole is identical to all of its parts, taken together. CEI seems to be inconsistent, since it seems to require that the parts of a whole possess incompatible number properties (for instance, being one thing and being many things).

Loop-generated neutrino masses in composite Higgs models

open access: yesJournal of High Energy Physics, 2021
We present a composite scotogenic model for neutrino masses, which are generated via loops of ℤ2-odd composite scalars. We consider three different approaches to the couplings of the neutrinos (including three right-handed singlets) and the composite ...

Inflation from the finite scale gauged Nambu–Jona-Lasinio model

open access: yesNuclear Physics B, 2017
The possibility to construct an inflationary universe scenario for the finite-scale gauged Nambu–Jona-Lasinio model is investigated. This model can be described by the Higgs–Yukawa type interaction model with the corresponding compositeness scale ...

Search for excited leptons in ℓℓγ final states in proton-proton collisions at s = 13 $$ \sqrt{\mathrm{s}}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2019
A search is presented for excited electrons and muons in ℓℓγ final states at the LHC. The search is based on a data sample corresponding to an integrated luminosity of 35.9 fb−1 of proton-proton collisions at a center-of-mass energy of 13 TeV, collected ...
