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...

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...
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...
Three-body force and the tetraquark interpretation of light scalar mesons
scalar meson tetraquark three-body force

We study the possible tetraquark interpretation of light scalar meson states a0(980), f0(980), κ,σ within the framework of the non-relativistic potential model. The wave functions of tetraquark states...
