Vector-like quark interpretation of excess in Higgs signal strength
There is a +2σ deviation in the average Higgs-signal strength for all the 7+8+13 TeV data up to Summer 2018. We find that a slight reduction of the bottom-Yukawa coupling can fit the data better than the standard model. We suggest an extension with a vector-like quark doublet, of which the right-han...
