Rotating mesons in the presence of higher derivative corrections from gauge-string duality

چکیده

We consider a rotating quark-antiquark (qq̄) pair in N = 4 thermal plasma. By using AdS/CFT correspondence, the properties of this system have been investigated. We study variation of rotating string radius at the boundary as a function of the tip of U-shape string and angular velocity of rotating meson. We also extend the results to the higher derivative corrections i.e. R2 and R4 which correspond to finite coupling corrections on the rotating quark-antiquark system in the hot plasma. In R4 case and for fixed angular velocity as λ decreases the string endpoints get more and more separated. To study R2 corrections, rotating quark-antiquark system in Gauss-Bonnet background has been considered. We summarize the effects of these corrections in the conclusion section.

How Does a Fundamental String Stretch its Horizon?

It has recently been shown that if we take into account a class of higher derivative corrections to the effective action of heterotic string theory, the entropy of the black hole solution representing elementary string states correctly reproduces the statistical entropy computed from the degeneracy of elementary string states. So far the form of the solution has been analyzed at distance scales...

DEVELOPMENT IN STRING THEORY

The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...

Higher Derivative Corrections in Holographic QCD

We consider the effect of the R4 term in type IIA string theory on the supergravity background dual to Nc D4 branes compactified on a circle with supersymmetry breaking boundary conditions. We study the dynamics of D8 branes in this perturbed geometry in the probe approximation. This leads to an analysis of higher derivative corrections in holographic QCD beyond the supergravity approximation. ...

Higher derivatives and brane-localised kinetic terms in gauge theories on orbifolds

We perform a detailed analysis of one-loop corrections to the self-energy of the (off-shell) gauge bosons in six-dimensional N = 1 supersymmetric gauge theories on orbifolds. After discussing the Abelian case in the standard Feynman diagram approach, we extend the analysis to the non-Abelian case by employing the method of an orbifoldcompatible one-loop effective action for a classical backgrou...

multi-instanton and string-loop corrections in toroidal orbifold models

The low energy limit of String Theory compactified to four dimensions is often described in terms of an effective supergravity which generically develops classical flat directions. Understanding the leading corrections from string loops and non-perturbative effects is therefore crucial for addressing questions such as moduli stabilization, supersymmetry breaking or cosmological evolution in the...
