Hadronic decay of a vector meson from the lattice
We explore the decay of a vector meson to two pseudoscalar mesons on the lattice with N f = 2 flavours of sea quark. Although we are working with quark masses that do not allow a physical decay, we show how the transition rate can be evaluated from the amplitude for ρ → ππ and from the annihilation component of ππ → ππ. We explore the decay amplitude for two different pion momenta and find cons...
متن کاملHadronic decay of a scalar B meson from the lattice
We explore the transitions B(0 +) to B π and Bs(0 +) to B K from lattice QCD with N f = 2 flavours of sea quark, using the static approximation for the heavy quark. We evaluate the effective coupling constants, predicting a B(0 +) to B π width of around 160 MeV. Our result for the coupling strength adds to the evidence that the Bs(0 +) meson is not predominantly a molecular state (BK).
متن کاملAn analysis of the vector meson spectrum from lattice QCD
We re-analyse meson sector data from the CP–PACS collaboration’s dynamical simulations [1]. Our analysis uses several different approaches, and compares the standard näive linear fit with the Adelaide Anzatz. We find that setting the scale using the J parameter gives remarkable agreement among data sets. Our predictions for the ρ and φ masses have very small statistical errors, ∼ 3 MeV, but the...
متن کامل| from the polarization of vector meson in the semileptonic decay of B and B c meson
Since the degree of polarization of the vector particle in semileptonic decay strongly influences the decay width of the particles, it can be used as a measure of Cabibbo-Kobayashi-Maskawa quark-mixing matrix elements. We show that |Vcb| can be determined from the measurement of polarization of vector meson in B̄, B̄c → V lν̄ decay, where V is vector meson. Typeset using REVTEX Present address: Ph...
متن کاملVector 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...
