## Errata for Basic Concepts of String Theory by Blumenhagen, Lüst and Theisen

This is an unofficial errata for the book *Basic Concepts of String Theory* by** **Ralph Blumenhagen, Dieter Lüst and Stefan Theisen. I couldn’t find an official errata, but I’ll probably discontinue this at some point when I do run into one.

**Chapter 2: The Classical Bosonic String**

- Page 8. The line below equation 2.3. There should be two dots, one each on and in the definition of .

**Chapter 8: The Quantized Fermionic String**

- Page 213: Equation 8.56. There is only one charge conjugation matrix in odd dimension d = 2n+1, either or . To find out which one it is, for odd , determine : if this is even, exists; if it is odd, exists. So, equation 8.56 is wrong: one should use for odd , and for even .To derive this criterion, compute and observe that it equals in general, which determines whether or . For a quick list of charge conjugation matrices in various dimensions and their symmetry properties, see page 11 of http://www.nikhef.nl/~t45/ftip/AppendixE.pdf.

**Chapter 14: String Compactifications**

- Page 510: Equation 14.262. The on the right-hand side in the local Lorentz transformation of the vielbein should be .

**Chapter 18: String Dualities and M-Theory**

- Page 690: The expression for in the paragraph below equation (18.26) has extra indices. It is the contraction of with .

## Los Alamos Science

Continuing the expository theme of my last post, I want to bring to your attention a collection of beautiful, crisp and entertaining articles by Richard Slansky in a 1984 publication of Los Alamos Science. They are available at

http://www.fas.org/sgp/othergov/doe/lanl/pubs/number11.htm

and are (in my opinion) must readings for students of theoretical physics, particularly those specializing in high energy theory, string theory, etc. In case you didn’t know, Slansky is also the author of a definitive review on group theory, which is a standard resource for particle physicists. It is worth having a printout of the review at your desk (and also an online copy in your tablet, smartphone, etc.) if you are interested in doing anything serious with group theory.

I should also take this opportunity to bring a list of Physics articles that have appeared over the years in Los Alamos Science. The comprehensive list of these articles with hyperlinks to online versions is at

## Review Articles – Particle Physics, String Theory, Supersymmetry and Supergravity

[to be updated]

A list of useful reviews on various aspects of string theory, branes, etc. is at http://www.nuclecu.unam.mx/~alberto/physics/stringrev.html. There are links to TASI lectures as well as review articles by prominent string theorists.

Another useful list of string theory papers and reviews is http://web.mit.edu/redingtn/www/netadv/Xstring.html.

Additionally, a list of books and useful review articles for supersymmetry and supergravity is at http://www.stringwiki.org/wiki/Supersymmetry_and_Supergravity.

A useful list of references for Collider Physics is at http://tigger.uic.edu/~keung/me/class/collider/web-docs.html.
