Factorization and generalized *-products
Youngjai Kiem, Dong Hyun Park, Sangmin Lee
The generalized *-products, or the -products, appear both in the one-loop effective action of noncommutative Yang-Mills theories and in the coupling of a closed string to N op…
Open string derivation of winding states in thermal noncommutative field theories
Youngjai Kiem, Dong Hyun Park, Haru-Tada Sato
The `winding state' behavior appears in the two-loop nonplanar contribution to the partition function in thermal noncommutative field theories. We derive this feature directly from…
Stretched strings and worldsheets with a handle
Youngjai Kiem, Dong Hyun Park, Haru-Tada Sato
In the presence of the constant background NS two-form gauge field, we construct the worldsheet partition functions, bulk propagators and boundary propagators for the worldsheets w…
Noncommutative Field Theory from String Theory: Two-loop Analysis
Youngjai Kiem, Sangmin Lee, Jaemo Park
Noncommutative ϕ^3 field theory in six dimensions exhibits the logarithmic UV/IR mixing at the two-loop order. We show that open string theory in the presence of constant backgroun…
UV/IR Mixing in Noncommutative Field Theory via Open String Loops
Youngjai Kiem, Sangmin Lee
We explicitly evaluate one-loop (annulus) planar and nonplanar open string amplitudes in the presence of the background NS-NS two-form field. In the decoupling limit of Seiberg and…
