Abstract

In this paper we discuss the QCD contribution to the Abelian Debye and magnetic screening masses in a deconfined QCD plasma at finite temperature in the presence of an external magnetic field B. We use a holographic AdS/QCD setup in an AdS Schwarzschild black hole background and show that the electric screening mass has a form similar to the one-loop result in QED. Moreover, we calculate the corrections due to the magnetic field to all orders of B and demonstrate that in the case when the magnetic field is large the Debye mass grows linearly with B, while the magnetic screening mass vanishes. The whole effect of the magnetic field turns out to stem from the Chern-Simons action. We also discuss the zero temperature case in the chiral perturbation theory.

Topological or rotational non-Abelian gauge fields from Einstein-Skyrme holography

Journal Article Cartwright, Casey; Harms, Benjamin; Kaminski, Matthias - Journal of High Energy Physics (Online)

We report analytically known states at non-zero temperature which may serve as a powerful tool to reveal common topological and thermodynamic properties of systems ranging from the QCD phase diagram to topological phase transitions in condensed matter materials. In the holographically dual gravity theory, these are analytic solutions to a five-dimensional non-linear-sigma (Skyrme) model dynamically coupled to Einstein gravity. This theory is shown to be holographically dual to \( \mathcal{N} \) = 4 Super-Yang-Mills theory coupled to an SU(2)-current. All solutions are fully backreacted asymptotically Anti-de Sitter (AdS) black branes or holes. One family of global AdS black hole solutionsmore »« less

AdS{sub 5} solutions in Einstein-Yang-Mills-Chern-Simons theory

Journal Article Brihaye, Yves; Radu, Eugen; Tchrakian, D - Physical Review. D, Particles Fields

We investigate static, spherically symmetric solutions of an Einstein-Yang-Mills-Chern-Simons system with negative cosmological constant, for an SO(6) gauge group. For a particular value of the Chern-Simons coefficient, this model can be viewed as a truncation of the five-dimensional maximal gauged supergravity and we expect that the basic properties of the solutions in the full model to persist in this truncation. Both globally regular, particlelike solutions and black holes are considered. In contrast with the Abelian case, the contribution of the Chern-Simons term is nontrivial already in the static, spherically symmetric limit. We find two types of solutions: the generic configurationsmore »« less

Anomalous form factor of the neutral pion in an extended AdS/QCD model with Chern-Simons term

Journal Article Grigoryan, H; Radyushkin, A - Physical Review. D, Particles Fields

We propose an extension of the hard-wall AdS/QCD model by including the Chern-Simons term required to reproduce the chiral anomaly of QCD. In the framework of this holographic model, we study the vertex function F{sub {pi}}{sub {gamma}}{sub *{gamma}}{sub *}(Q{sub 1}{sup 2},Q{sub 2}{sup 2}) which accumulates information about the coupling of the pion to two (in general virtual) photons. We calculate the slope of the form factor with one real and one slightly virtual photon and show that it is close to experimental findings. We analyze the formal limit of large virtualities and establish that predictions of the holographic model analyticallymore »« less

Anomalous Form Factor of the Neutral Pion in Extended AdS/QCD Model with Chern-Simons Term

Journal Article Radyushkin, Anatoly; Grigoryan, Hovhannes - Physical Review D

We propose an extension of the hard-wall AdS/QCD model by including the Chern-Simons term required to reproduce the chiral anomaly of QCD. In the framework of this holographic model, we study the vertex function F_{\pi \gamma^* \gamma^*}(Q_1^2,Q_2^2) which accumulates information about the coupling of the pion to two (in general virtual) photons. We calculate the slope of the form factor with one real and one slightly virtual photons and show that it is close to experimental findings. We analyze the formal limit of large virtualities and establish that predictions of the holographic model analytically (including nontrivial dependence on the ratiomore »« less

Thermodynamic properties of spontaneous magnetization in three-dimensional Chern-Simons QED

Journal Article Kanemura, S; Matsushita, T - Physical Review, D

The spontaneous magnetization in (2+1)-dimensional Chern-Simons QED is discussed in a finite temperature system. The thermodynamical potential is analyzed within the weak field approximation and in the fermion massless limit. We find that there is a linear term with respect to the magnetic field with a negative coefficient at any finite temperature. This implies that the spontaneous magnetic field does not vanish even at high temperature. In addition, we examine the photon mass spectrum in the system. We find that the bare Chern-Simons coefficient is canceled by the radiative effects. The photons then become topologically massless according to the magnetization,more »« less
