Very basic stuff on strings

Posted in AdS/CFT, Gauge Theory, String Theory by Index Guy on June 5, 2008

I would like to share some of the stuff I learned from


about basic notions from string theory and the AdS/CFT correspondence. The review is focused on gauge/gravity dualities and mesons, but it contains a nice overview of some concepts to bring readers up to speed. Some stuff bellow might be verbatim; most comes from the reference mentioned above.



What Alday & Maldacena did (I)

Posted in AdS/CFT, Gauge Theory, Paper discussion, Quantum Field Theory by Index Guy on June 3, 2008

Let us start with the work of Alday and Maldacena on scattering amplitudes of gluons at strong coupling (arXiv:0705.0303). I will summarize what I got from reading the first few pages below, but most of it is really verbatim from the preprint. For future references I will include some questions between square brackets that I need to answer. Section names headline summary of the corresponding preprint. Yes, I even summarized the “Abstract”. I know… 🙂
