More on the Tensor Response of the QCD Vacuum to an External Magnetic Field
A. Gorsky, P. N. Kopnin, A. Krikun +1
In this Letter we discuss a few issues concerning the magnetic susceptibility of the quark condensate and the Son-Yamamoto (SY) anomaly matching equation. It is shown that the SY r…
Anomalous QCD Contribution to the Debye Screening in an External Field via Holography
A. Gorsky, P. N. Kopnin, A. Krikun
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 mag…
On the Chiral Magnetic Effect in Soft-Wall AdS/QCD
A. Gorsky, P. N. Kopnin, A. V. Zayakin
The essence of the chiral magnetic effect is generation of an electric current along an external magnetic field. Recently it has been studied by Rebhan et al. within the Sakai--Sug…
Low-energy theorems and spectral density of the Dirac operator in AdS/QCD
P. N. Kopnin
We study the low-energy theorems of QCD from the point of view of the dual AdS/QCD models and demonstrate that these models are compatible with the theorems in the chiral limit, i.…
Manifestation of a singlet heavy up-type quark in the branching ratios of rare decays K to πν\barν, B to πν\barν and B to K ν\barν
P. N. Kopnin, M. I. Vysotsky
We investigate the implications of the model with a SU(2)-singlet up-type quark, heavy enough not to be produced at the LHC, namely, the contribution of the new quark to the branch…
