Bilocal Field Theory for Composite Scalar Bosons [PDF]
EntropyWe give a bilocal field theory description of a composite scalar with an extended binding potential that reduces to the Nambu–Jona-Lasinio (NJL) model in the pointlike limit.

Dipole operator constraints on composite Higgs models. [PDF]
Eur Phys J C Part Fields, 2014 Flavour- and CP-violating electromagnetic or chromomagnetic dipole operators in the quark sector are generated in a large class of new physics models and are strongly constrained by measurements of the neutron electric dipole moment and observables ...

Anarchy with linear and bilinear interactions
Journal of High Energy Physics, 2017 Composite Higgs models with anarchic partial compositeness require a scale of new physics O 10 − 100 $$ \mathcal{O}\left(10-100\right) $$ TeV, with the bounds being dominated by the dipole moments and ϵ K .

Effective-Range-Expansion Study of Near Threshold Heavy-Flavor Resonances
Advances in High Energy Physics, 2019 In this work, we study the resonances near the thresholds of the open heavy-flavor hadrons using the effective-range-expansion method. The unitarity, analyticity, and compositeness coefficient are also taken into account in our theoretical formalism.

Estimation of compositeness with correction terms [PDF]
EPJ Web of Conferences, 2022 The compositeness X is defined as the probability to observe the composite structure such as the hadronic molecule component in a bound state. One of the model-independent approaches to calculate X is the weak-binding relation.

Sp(4) gauge theories and beyond the standard model physics [PDF]
EPJ Web of Conferences, 2022 We review numerical results for models with gauge group Sp(2N), discussing the glueball spectrum in the large-N limit, the quenched meson spectrum of Sp(4) with Dirac fermions in the fundamental and in the antisymmetric representation and the Sp(4) gauge

Compositeness above the electroweak scale and a proposed test at LHCb [PDF]
EPJ Web of Conferences, 2022 I review attempts to construct models of partial compositeness from strongly coupled gauge theories. A few minimal assumptions allow one to isolate a small number of representative models.

Evolution of genuine states to molecular ones: The Tcc(3875) case
Physics Letters B, 2023 We address the issue of the compositeness of hadronic states and demonstrate that starting with a genuine state of nonmolecular nature, but which couples to some meson-meson component to be observable in that channel, if that state is blamed for a bound ...

Methods on compositeness and related aspects [PDF]
EPJ Web of Conferences, 2022 In many physical applications, bound states and/or resonances are observed, which raises the question whether these states are elementary or composite.

Electroweak precision tests of composite Higgs models
Journal of High Energy Physics, 2023 We study constraints on Composite Higgs models with fermion partial compositeness from electroweak precision measurements, including the 2022 W-boson mass result from the CDF collaboration.
