I want to decompose a tensor product using Littlewood-Richardson rule, How do I find the component of this in each irreducible space?
Let me set up the notation I am using. $(abc,de)$ denotes the standard Young tableau where the first row is $abc$ and the second row is $de$. Each young tableau corresponds to the young symmetriser, ...
The R-R sector of IIA and IIB are respectively given as, $8_s \otimes 8_c = \oplus  = 8_v \oplus 56_t$ $8_s \otimes 8_s = \oplus  \oplus _+ = 1 \oplus 28 \oplus 35_+$ Now looking at ...
I obviously have a problem with basics of group theory. consider an open string in flat spacetime. there are usually two common gauge to solve the classical problem and quantize the strings: ...
I would like to get some help in interpreting the main equation of the superconformal algebra (in $2+1$ dimenions) as stated in equation 3.27 on page 18 of this paper. I am familiar with supersymmetry ...
This is somewhat of a continuation of my previous question. I had stated there that a conformal spinor ($V$) of $SO(n,2)$ can be created by taking a direct sum of two $SO(n-1,1)$ spinors $Q$ and $S$ ...
