Yukawa textures, new physics, and nondecoupling
Yukawa textures, new physics, and nondecoupling
We point out that new physics can play an important role in rescuing some of the Yukawa texture-zero Ans\"atze which would otherwise be eliminated by the recent, more precise measurements of ${V}_{\mathrm{CKM}}$. As an example, a detailed analysis of a four texture-zero Ansatz is presented, showing how the presence of …
