New physics in singly Cabibbo-suppressed D decays
A U-spin relation among four ratios of amplitudes for D0→π+K−,K+π−,K+K−,π+π−, including first, second and third order U-spin breaking, has been derived recently with a precision of 10−3. We study effects of new |ΔC|=1 operators on this relation. We find that it is not affected by U-spin scalar opera...
