Semileptonic decays of K and D mesons in 2+1 flavor QCD
Semileptonic decays K and D mesons in 2+1 flavor QCD
2011/1/6
The experimentally measured rates of the semileptonic decays K -> pi l nu and D -> K(pi) l nu can be combined with lattice calculations of the associated form factors to precisely extract the CKM matr...

The experimentally measured rates of the semileptonic decays K -> pi l nu and D -> K(pi) l nu can be combined with lattice calculations of the associated form factors to precisely extract the CKM matr...
We review the physics of purely leptonic decays of $\pi^\pm$, $K^\pm$, $D^{\pm}$, $D_s^\pm$, and $B^\pm$ pseudoscalar mesons. The measured decay rates are related to the product of the relevant weak-i...
We search for new charmless decays of neutral $b$--hadrons to pairs of charged hadrons with the upgraded Collider Detector at the Fermilab Tevatron. Using a data sample corresponding to 1 fb$^{-1}$ of...

Within the heavy quark limit and the hierarchy approximation λQCD<< mD< analyze the B→D0D0 and Bs→D0D0 decays, which occur purely via annihilation type diagrams. As a rough estimate, we calcula...
