Nondiagonal neutral interactions in the six-quark scheme and the possible existence of the (cs)/sub R/ current

The effect of the current g/sup b//sub L/(sb)/sub L/+g/sup b//sub R/ (sb)/sub R/ on the b-quark decay widths is studied in order to obtain bounds on g/sup b//sub L/ and g/sup b//sub R/. The constant g/sup b//sub R/ is related to the constant g/sup c//sub R/ of the current (cs)/sub R/. It is shown that the conditions imposed on g/sup b//sub R/ are insufficient to confirm or deny the existence of the (cs)/sub R/ current. The Michel spectrum and the total width of the weak three-particle decay are calculated taking into account the masses of all the particles and all the interaction variants
