High Energy Theory Seminar
1/16 BPS States in N=4 SYM
In this talk I will discuss the problem of counting 1/16 BPS operators in N=4 Super-Yang-Mills theory at weak coupling. I will present the complete set of 1/16 BPS operators in the infinite N limit, which agrees with the counting of free BPS multi-graviton states in the gravity dual AdS5xS5. I will then present an conjecture that all 1/16 BPS operators in N=4 SYM are of the multi-graviton form, and give numerical evidences for this conjecture. I will discuss the implication of the conjecture and the seeming failure in reproducing the entropy of large 1/16 BPS black holes in AdS5. This talk is based on 1305.6314 with Xi Yin.
