Hadronic decay of a scalar B meson from the lattice

چکیده
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).

Combination of Colour Favoured and Colour
In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...

In this paper, the decay of Bc+ meson, which consists of two b and c heavy quarks, into the Do and K+ mesons was studied. Given that the experimental branching ratio for this decay was within the range of 3.75*10-5 to 11.16*10-5; it was decided to calculate the theoretical branching ratio by applying the final state interaction (FSI) through the T and cross-section channels. In this process, b...
متن کاملScalar glueball and meson spectroscopy in unquenched lattice QCD with improved staggered quarks
We present results of an exploratory study of singlet scalar states in unquenched QCD using both glueball and meson operators. Results for non-singlet non-strange scalar mesons are also presented. We use Asqtad improved staggered fermions and gauge configurations generated by the MILC collaboration at lattice spacings of .12 and .09 fm. In this formulation, the glueball mass is not significantl...
متن کاملProperties of light scalar mesons from lattice QCD . UKQCD Collaboration
Lattice QCD with N f = 2 flavours of sea quark is used to explore the spectrum and decay of scalar mesons. We find evidence that the lightest non-singlet scalar meson (a 0) has a mass of 1.01(4) GeV. We determine from the lattice the coupling strength to KK and πη. We compute the leptonic decay constant of the lightest non-singlet scalar meson. We discuss the impact of these lattice results on ...
متن کاملSemileptonic D decay into scalar mesons: a QCD sum rule approach
Semileptonic decays of D-mesons into scalar hadronic states are investigated. Two extreme cases are considered: a) the meson decays directly into an uncorrelated scalar state of two two mesons and b) the decay proceeds via resonance formation. QCD sum rules including instanton contributions are used to calculate total and differential decay rates under the two assumptions. PACS Numbers : 12.38....
