Axion quality from superconformal dynamics

چکیده
We discuss a possibility that superconformal dynamics induces the emergence of global U(1)PQ symmetry to solve strong CP problem through axion. Fields spontaneously breaking couple new quarks charged under ordinary color SU(3)C and SU(N) gauge group. The theory flows into an IR fixed point where fields hold large anomalous dimension leading suppression U(1)PQ-violating higher dimensional operators. spontaneous makes massive. is but not so axion couples only usual potential generated. also comment on model are realized as meson superfields in supersymmetric QCD.

Dyon-axion Dynamics
The discovery by Witten [ 1] that a magnetic monopole of minimal magnetic charge acquires electric charge -e0/2~r in a 0-vacuum has led to deep insights into the fermionic structure of monopoles [2]. In this note, we point out another implication of the Witten effect this effect induces a coupling between monopoles and axions. We compute the energy of the axion ground state in the field of a ma...
متن کاملOn dynamics of 5D superconformal theories
5D superconformal theories involve vacuum valleys characterized in the simplest case by the vacuum expectation value of the real scalar field σ. If 〈σ〉 6 = 0, conformal invariance is spontaneously broken and the theory is not renormalizable. In the conformally invariant sector 〈σ〉 = 0, the theory is intrinsically nonperturbative. We study classical and quantum dynamics of this theory in the lim...
متن کاملSuperconformal Dynamics and SUSY Flavor Problem
We study the scenario leading to hierarchical Yukawa couplings and at the same time degenerate sfermion masses. Superconformal dynamics plays a role. Understanding the origin of fermion masses and mixing angles is one of most important issues in particle physics. Yukawa couplings are free parameters within the framework of the standard model (SM). There are several types of flavor mechanisms to...
متن کاملD-Brane Dynamics and Logarithmic Superconformal Algebras
We construct the consistent supersymmetric extensions of the operators describing the recoil of a D-brane and show that they realize an N = 1 logarithmic superconformal algebra. The corresponding supersymmetric vertex operator is related to the action of a twisted superparticle with twist field determined by the angular momentum of the recoiling D-brane and with explicitly broken κ-symmetry. We...
متن کاملAxion Radiation from Strings
This paper revisits the problem of the string decay contribution to the axion cosmological energy density. We show that this contribution is proportional to the average relative increase when axion strings decay of a certain quantity Nax which we define. We carry out numerical simulations of the evolution and decay of circular and non-circular string loops, of bent strings with ends held fixed,...
