Introduction to String Theory and Gauge/Gravity duality for students in QCD and QGP phenomenology
Authors: Robi Peschanski (Saclay)
(Submitted on 20 Apr 2008)
Abstract: String theory has been initially derived from motivations coming from strong interaction phenomenology,but its application faced deep conceptual and practical difficulties. The strong interactions found their theoretical foundation elsewhere, namely on QCD, the quantum gauge field theory of quarks and gluons. Recently, the Gauge/Gravity correspondence allowed to initiate a reformulation of the connection between strings and gauge field theories, avoiding some of the initial drawbacks and opening the way to new insights on the gauge theory at strong coupling and eventually QCD. Among others, the recent applications of the Gauge/Gravity correspondence to the formation of the QGP, the quark-gluon plasma, in heavy-ion reactions seem to provide a physically interesting insight on phenomenological features of the reactions. In these lectures we will give a simplified introduction to those aspects of string theory which, at the origin and in the recent developments, are connected to strong interactions, for those students which are starting to learn QCD and QGP physics from an experimental or phenomenological point of view.

Dear Robi Peschanski (Saclay),

Thank you for sharing this informative and interesting introduction to string theory and its connection to gauge/gravity duality. As a scientist working in the field of QCD and QGP phenomenology, I am particularly interested in this topic and your work provides valuable insights and perspectives.

I appreciate the emphasis on the historical motivations for string theory, particularly its origins in strong interaction phenomenology. It is often easy to overlook the context and motivations behind scientific theories, and it is important to recognize the evolution of ideas and their applications.

The Gauge/Gravity correspondence is a fascinating concept that has opened up new possibilities for understanding the connections between strings and gauge field theories. The ability to reformulate and potentially solve some of the initial difficulties in applying string theory to strong interactions is a significant development.

I am also intrigued by the potential applications of the Gauge/Gravity correspondence to the formation of the QGP in heavy-ion reactions. The idea that this correspondence can provide insights into the phenomenological features of these reactions is an exciting prospect.

Overall, your lectures provide a valuable and accessible introduction to string theory for students in QCD and QGP phenomenology. Thank you for sharing your knowledge and expertise in this field. I look forward to learning more about the latest developments and applications of the Gauge/Gravity correspondence in this area.

I find this paper to be a valuable resource for students in the field of QCD and QGP phenomenology. The authors provide a comprehensive introduction to the concepts of string theory and gauge/gravity duality, and how they relate to the study of strong interactions in QCD and the formation of the quark-gluon plasma.

The paper highlights the historical connection between string theory and strong interaction phenomenology, and how this has evolved over time. The development of gauge/gravity duality has allowed for a new perspective on the relationship between strings and gauge field theories, providing a potential solution to some of the initial challenges faced in applying string theory to QCD.

The authors also discuss the recent applications of gauge/gravity duality to the formation of the quark-gluon plasma, a state of matter that is of great interest in heavy-ion reactions. This offers a new and potentially fruitful approach to understanding the phenomenological features of these reactions.

Overall, I believe this paper serves as a valuable resource for students looking to gain a deeper understanding of the connection between string theory and QCD/QGP phenomenology. It provides a clear and accessible introduction to these complex topics, making it a valuable addition to the literature on this subject.
