Theory review on rare K decays: Standard Model and beyond
with X = νν̄, ll, λq = V ∗ qsVqd. Without the dependence of the loop functions y q on the quark masses, CKM unitarity would imply vanishing FCNC (GIM mechanism). Now, looking at these dependences, combined with the scaling of the CKM elements, one can readily get a handle on the importance of each quark contribution. For X = νν̄, only the Z penguin and W box enter, y q ∼ m 2 q, and light quark co...
متن کاملRare Decays and Cp Violation beyond the Standard Model
We review the status of rare decays and CP violation in extensions of the Standard Model. We analyze the determination of the unitarity triangle and the model-independent constraints on new physics that can be derived from this analysis. We find stringent bounds on new contributions to K − K̄ and Bd − B̄d mixing, pointing either to models of minimal flavour violation or to models with new sources...
متن کاملRare Charm Decays in the Standard Model and Beyond
We perform a comprehensive study of a number of rare charm decays, incorporating the first evaluation of the QCD corrections to the short distance contributions, as well as examining the long range effects. For processes mediated by the c → ul+l− transitions, we show that sensitivity to short distance physics exists in kinematic regions away from the vector meson resonances that dominate the to...
متن کاملRARE K DECAYS AND NEW PHYSICS BEYOND THE STANDARD MODEL a
Rare decays provide a complementary window to direct collider searches as probes of physics beyond the Standard Model. We present an overview of the New Physics sensitivity provided by existing and future measurements of rare leptonic and semileptonic K decays within the context of several classes of models.
متن کاملRare Meson Decays in Theories beyond the Standard Model
In the standard model (SM), lepton L and baryon B number conservation takes place due to the accidental U(1)L × U(1)B symmetry existing at the level of renormalizable operators. But for many extensions of the SM it is not the case. The well known mechanism of lepton number (LN) violation is based on the mixing of massive Majorana neutrinos predicted by various Grand unified theories (GUTs) [1]....
