A ug 1 99 9 August 1999 WM - 99 - 114 Fourth Generation b ′ decays into b + Higgs

If a fourth generation quark exists whose mass is below 255 GeV, then the only two-body charged current decay, b → c + W , is doubly-Cabibbo suppressed. For this reason, CDF has searched for the one-loop neutral current decay b → b + Z, assuming that the branching ratio into b + Z is 100%; an analysis giving the bounds on mb′ for smaller branching ratios is in preparation. In this Brief Report,...

Assessing Change in Avian Influenza A(H7N9) Virus Infections During the Fourth Epidemic - China, September 2015-August 2016.

Since human infections with avian influenza A(H7N9) virus were first reported by the Chinese Center for Disease Control and Prevention (China CDC) in March 2013 (1), mainland China has experienced four influenza A(H7N9) virus epidemics. Prior investigations demonstrated that age and sex distribution, clinical features, and exposure history of A(H7N9) virus human infections reported during the f...
