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...

We investigate tensor mesons as quark-antiquark bound states in a fully covariant Bethe-Salpeter equation. As a first concrete step we report results for masses of J^{PC}=2^{++} mesons from the chiral...
Heavy mesons in dense matter
Heavy mesons dense matter
2010/12/29
Charmed mesons in dense matter are studied within a unitary coupled-channel approach which takes into account Pauli-blocking effects and meson self-energies in a self-consistent manner. We obtain the ...
KLOE results on scalar and pseudoscalar mesons
e+ e－ interactions φ-factory scalar mesons pseudoscalar mesons
2010/5/7
The data collected by the KLOE Collaboration at the Frascati φ-factory DAΦNE from 2001 to 2006 have been used for extensive studies in meson spectroscopy. The decays of the scalar mesons a0(980) and f...
We search for the flavor-changing neutral current decays D0 ! μ+μ− and D0 ! e+e−, and for the
lepton-flavor violating decays D0 ! e±μ using 660 fb−1 of data collected with the Bell...
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...
Dynamically generated N* resonances from the interaction of two mesons and a baryon
Few-body systems chiral dynamics S=0 resonances
2009/11/24
We have studied the ππN system and coupled channels by using of the Faddeev equations and two N* and one Δ states, all of them with JP=1/2+, have been found in the formalism as dynamically generated s...

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...
