New Heavy Bosons (${{\mathit W}^{\,'}}$, ${{\mathit Z}^{\,'}}$, leptoquarks, etc.), Searches for

 
We list here various limits on charged and neutral heavy vector bosons (other than ${{\mathit W}}$'s and ${{\mathit Z}}$'s), heavy scalar bosons (other than Higgs bosons), vector or scalar leptoquarks, and axigluons. The latest unpublished results are described in ``${{\mathit W}^{\,'}}$ Searches'' and ``${{\mathit Z}^{\,'}}$ Searches'' reviews. For recent searches on scalar bosons which could be identified as Higgs bosons, see the listings in the Higgs boson section.
