scalar mesons visible B+- --> pi+pi-pi+- decays
2011/1/5
Two pion effective mass and helicity angle distributions in the charged B-meson decays into three charged pions are studied. The weak decay amplitudes are calculated in the framework of the QCD factor...
In-Medium Modifications of Scalar Charm Mesons in Nuclear Matter
In-Medium Modifications Scalar Charm Mesons Nuclear Matter
2011/1/6
Employing QCD sum rules the in-medium modifications of scalar charm mesons in a cold nuclear matter environment are estimated. The mass splitting of D∗ − ¯D∗ is quantified.
The observation of new suppressed B0s decays, B0s ! J/yK(892)0 and B0s ! J/yK0 S , and the
measurement of their branching ratios is presented.

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 JPC = 2++ mesons from the chiral lim...
Semileptonic decays of K and D mesons in 2+1 flavor QCD
Semileptonic decays of K D mesons 2+1 flavor QCD
2011/1/6
The experimentally measured rates of the semileptonic decays K →p ln and D → K(p )ln can
be combined with lattice calculations of the associated form factors to precisely extract the CKM matrix eleme...

We discuss kinematical correlations between charged leptons from semileptonic decays of open
charm/bottom, leptons produced in the Drell-Yan mechanism as well as some other mechanisms
not included s...
