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.

Partial compositeness under precision scrutiny
Journal of High Energy Physics, 2022 We revisit the impact of top partial compositeness on electroweak precision observables in the misaligned vacuum basis. We identify a new source for S in the singlet mixing case, and for S-T in the bi-doublet mixing, stemming from misalignment in the ...

Generalized weak-binding relations of compositeness in effective field theory [PDF]
Progress of Theoretical and Experimental Physics, 2017 We study the compositeness of near-threshold states to investigate the internal structure of exotic hadron candidates. Within the framework of effective field theory, Weinberg's weak-binding relation is extended to more general cases by easing several ...

The other effective fermion compositeness
Journal 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

Modelling vector-like quarks in partial compositeness framework
Journal of High Energy Physics, 2022 Composite Higgs models, together with partial compositeness, predict the existence of new scalars and vector-like quarks (partners) at and above the TeV scale.

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 .

Revealing timid pseudo-scalars with taus at the LHC [PDF]
European Physical Journal C: Particles and Fields, 2018 A light pseudo-scalar that is copiously produced at the LHC may still be allowed by present searches. While masses above 65 GeV are effectively covered by di-photon searches, the lower mass window can be tested by a new search for boosted di-tau ...

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.
