A bstractIn the Higgs search at the LHC, a light Higgs boson $\left( {{115}\,{\text{GeV}} \lesssim {M_{\text{H}}} \lesssim {13}0\,{\text{GeV}}} \right)$ is not excluded by experimental data. In this mass range, the width of the Standard Model Higgs boson is more than four orders of magnitude smaller than its mass. The zero-width approximation is hence expected to be an excellent approximation. We show that this is not always the case. The inclusion of off-shell contributions is essential to… Expand
