Available in PDF, EPUB and Kindle. Book excerpt: The authors present a search for t[r-arrow] bH[sup+] in t[bar t] candidate events at D0 based on two methods. The first seeks a deficit in signal relative to expectations from the standard model (SM). Such a deficit would imply the presence of a non-SM decay of the top quark. This search involves the full data sample of[approx] 110 pb[sup[minus]1] of p[bar p] collisions at[radical]s= 1.8 TeV, collected with the D0 detector. The second method looks for charged Higgs decays to[tau] leptons (and associated neutrinos), and is based on a 62 pb[sup[minus]1] subset of the aforementioned data sample.
