Supercurrent interactions in noncommutative Yang–Mills and IIB matrix model Original Research Article

It is known that noncommutative Yang–Mills is equivalent to IIB matrix model with a noncommutative background, which is interpreted as a twisted reduced model. In noncommutative Yang–Mills, long range interactions can be seen in nonplanar diagrams after integrating high momentum modes. These interactions can be understood as block–block interactions in the matrix model. Using this relation, we consider long range interactions in noncommutative Yang–Mills associated with fermionic backgrounds. Exchanges of gravitinos, which couple to a supersymmetry current, are examined.
