Fermion mass effects on {\Gamma(Z\ra b\bar{b} + a~light~Higgs)} in a two-Higgs-doublet model
Large fermion mass effect on the Yukawa process Z \ra b\bar{b}\ra b\bar{b} h
(A) in the entire range of the neutral Higgs boson masses is found. It is
particularly important for light Higgs bosons, which are still not excluded
experimentally in a general two-Higgs-doublet model.Comment: LaTeX file, 4 pages, 3 figures (in postscript) in a separate fil
New Physics at HERA: Implications for e+e- Scattering at LEP2
The impact of virtual leptoquark or R-parity breaking squark exchange as well
as generic contact interactions on the production of quark-antiquark pairs in
annihilation, in particular at LEP2, is summarized. An exciting
possibility of sneutrino formation in scattering is also mentioned.Comment: 4 pages, LaTeX, 3 figures included, uses aipproc.sty and epsfig; Talk
