U-spin Symmetry in Charmless B Decays
We prove a general theorem about equal CP rate differences within pairs of U-spin related charmless B and B_s decays. Six pairs of decays into two pseudoscalar mesons are identified where such relations hold. Ratios of corresponding rate differences and certain ratios of rates measure U-spin breakin...
