Title: The axion mass from 5D small instantons

Abstract

We calculate a new contribution to the axion mass that arises from gluons propagating in a 5th dimension at high energies. By uplifting the 4D instanton solution to five dimensions, the positive frequency modes of the Kaluza-Klein states generate a power-law term in the effective action that inversely grows with the instanton size. This causes 5D small instantons to enhance the axion mass in a way that does not spoil the axion solution to the strong CP problem. Moreover this enhancement can be much larger than the usual QCD contribution from large instantons, although it requires the 5D gauge theory to be near the non-perturbative limit. Thus our result suggests that the mass range of axions (or axion-like particles), which is important for ongoing experimental searches, can depend sensitively on the UV modification of QCD.

Enhanced EDMs from small instantons

Journal Article Bedi, Ravneet S. ; Gherghetta, Tony ; Pospelov, Maxim - Physical Review D

We show that models in which the strong CP problem is solved by introducing an axion field with a mass enhanced by non-QCD UV dynamics at a scale Λ_SI exhibit enhanced sensitivity to external sources of CP violation. In the presence of higher-dimensional CP-odd sources at a scale Λ_CP, the same mechanisms that enhance the axion mass also modify the axion potential, shifting the potential minimum by a factor ∝ Λmore »« less

Small instantons in weakly-gauged holographic models

Journal Article Gherghetta, Tony ; Pomarol, Alex - Journal of High Energy Physics (Online)

Small instantons can play an important role in Yang-Mills theories whose gauge couplings are sizeable at small distances. An interesting class of theories where this could occur is in weakly-gauged holographic models (dual to Yang-Mills theories interacting with strongly-coupled CFTs), since gauge couplings are indeed enhanced towards the UV boundary of the 5D AdS space. However, contrary to expectations, we show that small instantons in these non-asymptotically-free models are highly suppressed and ineffective. This is due to the conservation of topological charge that forbids instantons to be localized near the UV boundary. Despite this fact we find non-trivial UV localizedmore »« less

Fermion mass hierarchy and phenomenology in the 5D Domain Wall Standard Model

Journal Article Okada, Nobuchika ; Raut, Digesh ; Villalba, Desmond - Journal of High Energy Physics (Online)

We have recently proposed a setup of the “Domain-Wall Standard Model” in 5D spacetime, where all the Standard Model (SM) fields are localized in certain domains of the extra 5th dimension. Utilizing this setup, we attempt to solve the fermion mass hierarchy problem of the SM. The mass hierarchy can be naturally explained by suitably distributing the fermions in different positions along the extra dimension. Due to these different localization points, the effective 4D gauge couplings of Kaluza-Klein (KK) mode gauge bosons to the SM fermions become non-universal. As a result, our model is severely constrained by the Flavor Changingmore »« less

Dynamical axion misalignment with small instantons

Journal Article Buen-Abad, Manuel A. ; Fan, JiJi - Journal of High Energy Physics (Online)

We present a new mechanism to relax the initial misalignment angle of the QCD axion and raise the cosmological bound on the axion decay constant. The QCD axion receives a contribution from small UV instantons during inflation, which raises its mass to the inflationary Hubble scale. This makes the axion start rolling down its potential early on. In the scenario, the standard model Yukawa couplings of quarks are dynamical, being of order one during the inflationary era and reducing to their standard model values once it ends. This means that after inflation the contribution of the small instantons is suppressed,more »« less

Flavor-violation tests of the warped/composite standard model in the two-site approach

Journal Article Agashe, Kaustubh ; Azatov, Aleksandr ; Lijun, Zhu - Physical Review. D, Particles Fields

We study flavor violation in the quark sector in a purely 4D, two-site effective field theory description of the standard model (SM) and just their first Kaluza-Klein excitations from a warped extra dimension. The warped 5D framework can provide solutions to both the Planck-weak and flavor hierarchies of the SM. It is also related (via the AdS/CFT correspondence) to partial compositeness of the SM. We focus on the dominant contributions in the two-site model to two observables which we argue provide the strongest constraints from flavor violation, namely, {epsilon}{sub K} and BR(b{yields}s{gamma}), where contributions in the two-site model occur atmore »« less
