Partial compositeness under precision scrutiny [PDF]
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 ...

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.

Neutrino masses from low scale partial compositeness [PDF]
Journal of High Energy Physics, 2021 We consider a class of models in which the neutrinos acquire Majorana masses through mixing with singlet neutrinos that emerge as composite states of a strongly coupled hidden sector.

Modelling vector-like quarks in partial compositeness framework [PDF]
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.

Real and complex fundamental partial compositeness [PDF]
Journal 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 [PDF]
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

Bilocal Field Theory for Composite Scalar Bosons. [PDF]
Entropy (Basel)We 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.

The bearable compositeness of leptons [PDF]
Journal of High Energy Physics, 2018 Partial compositeness as a theory of flavor in the lepton sector is assessed. We begin presenting the first systematic analysis of neutrino mass generation in this context, and identifying the distinctive mass textures.

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 ${\cal O}(10-100)$ TeV, with the bounds being dominated by the dipole moments and $\epsilon_K$.

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 ...
