The usual practice during that time was to use IV and oral contrast for all abdominal CTs unless the creatinine was greater than 1.5mg/dL or the(More)
A search is made for charged Higgs bosons predicted by Two-Higgs-Doublet extensions of the Standard Model (2HDM) using electron-positron collision data collected by the OPAL experiment at √ s = 189–209 GeV, corresponding to an integrated luminosity of approximately 600 pb −1. Charged Higgs bosons are assumed to be pair-produced and to decay into q¯ q, τ ν τ(More)
