In this talk we describe our approach for the computation of multi-leg one-loop amplitudes and present some first results relevant for LHC phenomenology.

We formulate and prove a B-model disc level large N duality result for general conifold transitions between compact Calabi-Yau spaces using degenerations of Hodge structures.

Classification of N = 4 superconformal symmetries in two dimensions is reexamined. It is proposed that apart from SU(2) and SU(2)×SU(2)×U(1) their Kac-Moody symmetry can also be SU(2) × (U(1)) 4. These supercon-formal symmetries and corresponding algebras are named small, large and middle ones respectively. Operator product expansions for the middle algebra are derived.
