Scalar Absorption by Noncommutative D3-branes

The classical cross section for low energy absorption of the RR-scalar by a stack of noncommutative D3-branes in the large NS B-field limit is calculated. In the spirit of AdS/CFT correspondence, this cross section is related to two point function of a certain operator in noncommutative Yang-Mills theory. Compared at the same gauge coupling, the result agrees with that of obtained from ordinary D3-branes, consistent with the expectation that ordinary and noncommutative Yang-Mills theories are equivalent at long distances
