Abstract
We revisit the impact of top partial compositeness on electroweak precision observables in the misaligned vacuum basis. We identify a new source for in the singlet mixing case, and for - in the bi-doublet mixing, stemming from misalignment in the gauge couplings of the top partners. Hence, a positive shift in can be obtained in both cases, as preferred by the recent CDF measurement of the mass. These results, obtained for the minimal fundamental coset SU(4)/Sp(4), apply to any composite Higgs model with top partial compositeness.
