【 摘 要 】

A boundary-state computation is performed to obtain derivative corrections to the Chern–Simons coupling between a 𝑝-brane and the RR gauge potential 𝐶𝑝-3. We work to quadratic order in the gauge field strength 𝐹, but all orders in derivatives. In a certain limit, which requires the presence of a constant 𝐵-field background, it is found that these corrections neatly sum up into the *2 product of (commutative) gauge fields. The result is in agreement with a recent prediction using noncommutativity
