Title: Composite vectorlike fermions

Abstract

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.

Dynamical fermion mass generation by strong gauge interaction shielded by a scalar field

Journal Article Frick, C; Jersak, J - Physical Review, D

The strongly coupled lattice gauge models with confined fermion and scalar matter fields, which in a certain phase break dynamically a global chiral symmetry, are reconsidered from the point of view of the existence of heavy fermions. In these models heavy fermions can arise as neutral bound states of the fundamental fermion and scalar. We call this mechanism of dynamical fermion mass generation the {ital shielded} {ital gauge} {ital mechanism}. The scalar field induces at strong gauge coupling a second order phase transition which is necessary for a continuum limit. Therefore the mechanism might well exist also in continuum. Inmore »« less

Fermion and weak-boson masses in a composite model

Journal Article Margolis, B; Mendel, R - Phys. Rev. D; (United States)

In a model where quarks and leptons are fermion-boson composites we show that a realistic mass spectrum and flavor mixing can be obtained in a natural way. A metacolor SU(n)/sub MC/ gauge interaction, which is supposed to confine at a scale ..lambda../sub MC/approx.2 TeV is responsible for the binding. The elementary fermions carry all the SU(2)/sub L/ x U(1)/sub Y/ x SU(3)/sub C/ quantum numbers, while the number N of different elementary scalars determines the number of light composite families. The 't Hooft anomaly conditions impose the constraint n = N. The light fermions acquire their masses through transitions tomore »« less

Tau anomaly and vectorlike families

Journal Article Babu, K; Pati, J; Zhang, X - Physical Review, D (Particles Fields); (United States)

The implications of a recently indicated increase in {tau} lifetime are discussed. It is stressed that the available experimental constraints (from {delta}{rho},{epsilon}{sub 3}, and {ital N}{sub {nu}}, etc.) are satisfied most naturally if the indicated {tau} anomaly is attributed to the mixing of the {tau} family with a heavy vectorlike family {ital Q}{sub {ital L},}{ital R}{sup {prime}} with masses {similar to}200 GeV to 2 TeV, which is a doublet of SU(2){sub {ital R}} and singlet of SU(2){sub {ital L}}, rather than with a heavy fourth family with standard chiral couplings. {ital L}{leftrightarrow}{ital R} symmetry would imply that {ital Q}{sub {italmore »« less

Top-bottom-tau Yukawa coupling unification in the MSSM plus one vectorlike family and fermion masses as IR fixed points

Journal Article Dermíšek, Radovan; McGinnis, Navin - Physical Review. D.

In the MSSM extended by a complete vectorlike family, precise top, bottom and tau Yukawa coupling unification can be achieved assuming SUSY threshold corrections which are typical for comparable superpartner masses. Furthermore, the unification is possible with a large unified coupling, implying that all three fermion masses can be simultaneously close to their IR fixed points. Assuming unified Yukawa couplings of order one or larger, the preferred common scale of new physics (superpartners and vectorlike matter) is in the 3 TeV to 30 TeV range, with larger couplings favoring smaller scales.

A 750 GeV messenger of dark conformal symmetry breaking

Journal Article Davoudiasl, Hooman; Zhang, Cen - Physical Review D

The tentative hints for a diphoton resonance at a mass of ~750 GeV from the ATLAS and CMS experiments at the LHC may be interpreted as first contact with a “dark” sector with a spontaneously broken conformal symmetry. The implied TeV scale of the dark sector may be motivated by the interaction strength required to accommodate a viable thermal relic dark matter (DM) candidate. We model the conformal dynamics using a Randall-Sundrum-type five-dimensional geometry whose IR boundary is identified with the dynamics of the composite dark sector, while the Standard Model (SM) matter content resides on the UV boundary, correspondingmore »« less
