Final state rescattering as a contribution to B->rho gamma
Radiation gamma $$$gamma scattering
2014/12/22
We provide a new estimate of the long-distance component to the radiative transition $B \to \rho \gamma$. Our mechanism involves the soft-scattering of on-shell hadronic products of nonleptonic $B$ de...
We determine the value of the omega -rho- pi mesons coupling (g_{omega rho pi}), in the context of the vector meson dominance model, from radiative decays, the omega -> 3 pi decay width and the e^+e^-...
Chiral symmetry breaking and the spin content of the rho and rho' mesons
Chiral symmetry breaking rho rho' mesons
2011/7/21
Using interpolators with different SU(2)_L \times SU(2)_R transformation properties we study the chiral symmetry and spin contents of the rho- and rho'-mesons in lattice simulations with dynamical qua...

We perform a non-perturbative lattice calculation of the P-wave pion-pion scattering phase in the rho-meson decay channel using two flavors of maximally twisted mass fermions at pion masses ranging fr...
While the masses of light hadrons have been extensively studied in lattice QCD simulations, there exist only a few exploratory calculations of the strong decay widths of hadronic resonances. We will p...

Density-dependent nuclear interactions and the beta decay of 14C: chiral three-nucleon forces and Brown-Rho scaling
Effective field theory at finite density chiral three-nucleon force Brown-Rho scaling
2011/1/7
We study the role of density-dependent low-momentum nucleon-nucleon interactions in describing the anomalously long beta decay lifetime of 14C. We approach this problem both from the perspective of ch...

We perform a non-perturbative lattice calculation of the P-wave pion-pion scattering phase in
the -meson decay channel using two flavors of maximally twisted mass fermions at pion masses

We show that ratios of tree and penguin amplitudes in B-> K*pi and B->rho K are two to three times larger than in B-> K pi. This allows for considerably larger CP asymmetries in the former processes t...
