The flavour of SU(15) composite quarks and leptons
Benoît Assi, Ryan Plestid, Amartya Sengupta +1
We study the flavour structure of an confining chiral gauge theory in which the Standard Model (SM) quarks, leptons, and Higgs emerge as composite bound states. The coup…

EFT Validity and Truncation Uncertainty from few Nuisance Parameters
Benoît Assi, Adam Martin, William Shepherd
An observable in an Effective Field Theory (EFT) is an expansion in a set of small parameters, no different than any other perturbation series. Truncating such a series expansion l…

Neutrino Dipole Moments and Radiative Signatures from Partial Compositeness
Benoît Assi, Pedro A. N. Machado
We investigate composite neutrino models where heavy neutrinos emerge as bound states from a near-conformal strongly coupled sector. Standard Model neutrinos mix with these composi…
