Using data taken with the CLEO II detector, they have studied the decays of the D{sup 0} to K{sup +}K{sup -}, K{sup 0}{bar K}{sup 0}, K{sub S}{sup 0}K{sub S}{sup 0}, K{sub S}{sup 0}K{sub S}{sup 0}{pi}{sup 0}, K{sup +}K{sup -}{pi}{sup 0}. The authors present significantly improved results for B(D{sup 0} {yields} K{sup +}K{sup -}) = (0.454 {+-} 0.028 {+-} 0.035)%, B(D{sup 0} {yields} K{sup 0}{bar K}{sup 0}) = (0.054 {+-} 0.012 {+-} 0.010)% and B(D{sup 0} {yields} K{sub S}{sup 0}K{sub S}{sup 0}K{sub S}{sup 0}) = (0.074 {+-} 0.010 {+-} 0.015)% where the first errors are statistical and the second errors are the estimate of their systematic uncertainty. They also present a new upper limit B(D{sup 0} {yields} K{sub S}{sup 0}K{sub S}{sup 0}{pi}{sup 0}) < 0.059% at the 90% confidence level and the first measurement of B(D{sup 0} {yields} K{sup +}K{sup -}{pi}{sup 0}) = (0.14 {+-} 0.04)%.
