The schedule for this Journal Club on String Theory will be as follows:

1) The latest news in the world of strings Please bring recent papers that caught your attention and briefly summarize motivations, methods and results.

2) "On effective actions of BPS branes and their higher derivative corrections"

discussion led by Ehsan, Hatefi 

Abstract:  we will discuss the recent paper 1003.0314. First we would like to talk very briefly about S-matrix elements in string theory. Especially we will consider Liu's formula to generalize it to find the correlation function between two spin operators, arbitrary numbers of currents and fermion fields. Finally we want to obtain higher derivative extensions of four gauge field couplings of the Born-Infeld action to all orders of $\alpha'$, which are exactly consistent with the S-matrix element of one closed string RR field and three gauge fields on the world volume of a BPS brane.
