## Scattering amplitudes à la Alday-Maldacena (I)

I would like to summarize the work of Luis Fernando Alday and Juan Maldacena on gluon scattering amplitudes at strong coupling via AdS/CFT methods. I will follow mostly (i.e. verbatim) these two preprints from the arXiv:

## Very basic stuff on AdS/CFT

We continue our discussion (started here) of very basic notions in the study of the AdS/CFT correspondence. I have followed very closely the following review:

## Very basic stuff on strings

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)

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… 🙂

## Notes on BRST

Just found a nice set of lectures notes on BRST quantization on the arXiv:

Will try to go through it later.
