Abstract:

I will discuss an alternative method of probing trilinear Higgs self coupling in single Higgs production and decay channels at the LHC. We study the effects of anomalous trilinear coupling in NLO EW corrections to single Higgs processes. We identify the distributions that are more sensitive to the trilinear coupling. Finally, we perform a global fit at inclusive and differential level to constrain the trilinear coupling at current and future LHC runs. We find that the indirect constraints on trilinear coupling thus obtained are competitive and complementary to those obtained from double Higgs production measurements at the LHC.
