The properties of new gauge bosons have been studied in an asymmetric left-right model where the light quarks and leptons get their masses through radiative corrections. The charged gauge bosons {ital W}{sub {ital L}}{sup {plus minus}} and {ital W}{sub {ital R}}{sup {plus minus}} are mixed at the one-loop level. The Feynman diagram of this mixing via the fermion loop is calculated to be finite and the magnitude of this mixing angle is found to be not greater than 10{sup {minus}5}. By fitting neutral-current data, the lower bound on the mass of the second {ital Z} boson is 385 GeV and the Weinberg angle corresponding to the right-hand sector sin{sup 2}{theta}{sub {ital R}} is 0.3867{plus minus}0.2255 if the breaking energy scales of SU(2){sub {ital R}} are all at least 1 TeV or greater. The process {ital e}{sup +}{ital e{minus}}{r arrow}{mu}{sup +}{mu}{sup {minus}} is analyzed and an approximately linear relation between the total width of the second {ital Z} boson and its mass is obtained. The angular distribution shows that the property of forward-backward asymmetry does not change qualitatively.
