Reinikainen, S. Rinta-Antila, N. Soukouti, A. Voss, and J. Äystö Precise measurements of superallowed 0 + → 0 + β decay presently provide the most precise value for the weak mixing amplitude V u d . As the largest element of the CKM matrix, V u d is a critical piece of the Standard Model of the electroweak interaction. The new, precise Penning-trap mass measurement of the decay energy for the superallowed transition in 42 Sc opens the door for a much more precise f t value determination if its half-life can be measured more precisely as well.
