DESCRIPTION:Vera-Maria Enckell\nI'll discuss the dependency of Higgs infla
 tion on the non-renormalisable matching between the low energy Standard Mo
 del limit and the inflationary regime at high energies. In the top mass ra
 nge mt>171.8 GeV the scenario robustly predicts the spectral index n_s≈0
 .97 and the tensor-to-scalar ratio r≈0.003. The matching is however non-
 trivial\, even the best-fit values m_h = 125.09 GeV and m_t= 173.21 GeV re
 quire a jump δλ ∼ 0.01 in the Higgs coupling below the inflationary sc
 ale. For m_t<171.8 GeV\, the matching may generate a feature in the inflat
 ionary potential. In this case the predicted values of n_s and r vary but 
 the model is still falsifiable. For example\, a detection of negative runn
 ing of spectral index at level α_s <−0.01 would rule out Higgs inflatio
 n. The talk is based on a work with Sami Nurmi and Kari Enqvist [arXiv: 16
 03.07572].
