Constraining $I^½$ SMEFT coefficients: the case of the extra $U (1)^{'}$

Pietro Colangelo, Fulvia De Fazio, Francesco Loparco +1

We study the constraints on low-energy coefficients of the $I^½$ SMEFT generalization of the Standard Model effective theory in the simple case of a $U (1)^{'}$ enlargement…

New Physics couplings from angular coefficient functions of $B ˉ \to D^{*} (D I ¨ ) ℓ I^ˉ ½_{ℓ}$

Pietro Colangelo, Fulvia De Fazio, Francesco Loparco +1

The Belle Collaboration has recently measured the complete set of angular coefficient functions for the exclusive decays $B ˉ \to D^{*} (D I ¨ ) ℓ I^ˉ ½_{ℓ}$ , with $\ell=e,\,Î…
