Title: Composite vectorlike fermions

Journal Article · · Physics Letters. B
;

We study a dynamical mechanism that generates a composite vectorlike fermion, formed by the binding of an N-tuplet of elementary chiral fermions to an N-tuplet of scalars. Deriving the properties of the composite fermion in the large N limit, we also show that its mass is much smaller than the compositeness scale when the binding coupling is near a critical value. Furthermore, we compute the contact interactions involving four composite fermions, and find that their coefficients scale as 1/N. Physics beyond the Standard Model may include composite vectorlike fermions arising from this mechanism.
