We propose a new U(1) gauge interaction in the bulk in higher dimensional
spacetime, which transmits supersymmetry-breaking effects on the hidden brane
to the observable our brane. We find that rather small gauge coupling constant
of U(1)_{bulk}, αbulk≃5×10−4, is required for a
successful phenomenology. This result implies the compactification length L
of the extra dimension to be L−1≃2×1015GeV for
(4+1)-dimensional spacetime. This large compactification length L is a
crucial ingredient to suppress unwanted flavor-changing neutral currents and
hence our proposal is very consistent with the Randall-Sundrum brane-world
scenario.Comment: 9 pages, Late
