摘要：

We demonstrate that four top-quark production is a powerful tool to constrain the top Yukawacoupling. The constraint is robust in the sense that it does not rely on the Higgs boson decay. Taking into account the projection of the ttH production by the ATLAS Collaboration, we obtained a bound on the Higgs boson width, GH <= 2.57G(H)(SM), at the 14 TcV Large Hadron Collider with an integrated luminosity of 300 fb(-1).
