Vector Meson Decay of Baryon Resonances
One of the evidences for the discovery of a new state of matter that was quoted by the CERN press release in 2000 was the result of the CERES experiment that showed an excess of dileptons at invariant masses below the vector meson mass. In order to understand this phenomenon it is essential to consider the effect of conventional hadronic interactions on the vector mesons. We emphasize the relev...
متن کاملVector and pseudoscalar charm meson radiative decays.
Combining heavy quark effective theory and the chiral Lagrangian approach we investigate radiative decays of pseudoscalar D mesons. We first reanalyse D∗ → Dγ decays within the effective Lagrangian approach using heavy quark spin symmetry, chiral symmetry Lagrangian, but including also the light vector mesons. We then investigate D → V γ decays and calculate the D → K̄∗0γ and D → ργ partial widt...
متن کاملSemileptonic decay of a heavy-light pseudoscalar to a light vector meson
Semileptonic decays of heavy-light mesons are of interest because they can be used to determine elements of the CKM matrix. The nonperturbative QCD information needed to understand a decay can be calculated in lattice QCD. In the case of the decays D → K∗ and Ds → φ the branching ratios have been accurately measured and the relevant CKM matrix element (Vcs) is well determined by other methods [...
متن کاملDynamically generated resonances from vector meson-vector meson interaction based on a hidden-gauge unitary approach
We present a recent study of vector meson-vector meson interaction using a unitary approach based on the hidden-gauge Lagrangians. We find that 11 states get dynamically generated, corresponding to poles of the scattering matrices on the second Riemann sheet. Five of them are associated to the f0(1370), f0(1710), f2(1270), f ′ 2(1525), and K ∗ 2 (1430), by comparing the mass, width, and decay p...
