Search for New Heavy Particles in the ${\mathrm{WZ}}^0$ Final State in $\mathit{p}\overline{p}$ Collisions at $\sqrt{s}=1.8\mathrm{TeV}$

We present the first general search for new heavy particles, $X$, which decay via $X\to {\mathrm{WZ}}^0\to e\nu +jj$ as a function of $M_X$ and $\Gamma \left(X\right)$ in $p\overline{p}$ collisions at $\sqrt{s}=1.8\mathrm{}\mathrm{TeV}$. No evidence is found for production of $X$ in $110{\mathrm{pb}}^{-1\mathrm{}}$ of data collected by the Collider Detector at Fermilab. General cross section limits are set at the $95\%$ C.L. as a function of mass and width of the new particle. The results are further interpreted as mass limits on the production of new heavy charged vector bosons which decay via $W^{\prime }\to {\mathrm{WZ}}^0$ in an extended gauge model as a function of the width, $\Gamma \left(W^{\prime }\right)$, and mixing factor between the $W^{\prime }$ and the standard model $W$ bosons.
