Abstract

Electroweak radiative one-loop corrections to Higgs boson pair production in tt¯ fusion processes are calculated in the two-Higgs-doublet extension of the standard model. The numerical size of the nonstandard corrections is discussed for the process tt¯→ $H_{0}$ $H_{0}$ . The relative difference between the predictions of the two-Higgs-doublet model and the minimal standard model for a light scalar $M_{H_{1}}$ and heavy $M_{H_{2}}$ and $M_{Φ}$ easily exceeds -10% in the forward and backward directions. In particular the angular-dependence corrections owing to the nonstandard Higgs bosons get larger where the box and cubic Higgs boson vertex corrections constitute the dominant part of the radiative corrections. © 1996 The American Physical Society.
