چکیده

Introduction. Charged mesons formed from a quark and an anti-quark can decay to a charged lepton and a neutrino when these objects annihilate via a virtual W boson [1]. Fig. 1 illustrates this process for the purely leptonic decay of a D + meson.

Decay constants of P- and D-wave heavy-light mesons.

We investigate decay constants of P and D-wave heavy-light mesons within the mock-meson approach. Numerical estimates are obtained using the relativistic quark model. We also comment on recent calculations of heavy-light pseudo-scalar and vector decay constants. Typeset using REVTEX

Lattice QCD with two light Wilson quarks and maximally twisted mass

We summarise status and recent results of the European Twisted Mass collaboration (ETMC). The collaboration has been generating gauge configurations for three different values of the lattice spacing a . 0.1 fm and values of the charged pseudo scalar mass as low as 300 MeV with two flavours of maximally twisted mass quarks. We provide evidence that O(a) improvement works very well with maximally...

Decay Constants of Pseudo-scalar Mesons in Bethe-Salpeter Framework with Generalized Structure of Hadron-Quark Vertex

We employ the framework of Bethe-Salpeter equation under Covariant Instantaneous Ansatz to study the leptonic decays of pseudoscalar mesons. The Dirac structure of hadron-quark vertex function Γ is generalized to include various Dirac covariants besides γ5 from their complete set. The covariants are incorporated in accordance with a power counting rule, order by order in powers of the inverse o...

The heavy mesons in Nambu–Jona-Lasinio model

We propose an extended Nambu–Jona-Lasinio model to include the heavy mesons with the heavy quark symmetry. The quark current-current interaction is generalized to include the heavy quark currents. In order to comply with the heavy quark spin symmetry at the heavy quark limit, the quark mass dependence of the interaction strength is introduced. The light and heavy pseudo-scalar and vector meson,...

A Numerical Study of Partially Twisted Boundary Conditions

We investigate the use of partially twisted boundary conditions in a lattice simulation with two degenerate flavours of improved Wilson sea quarks. The use of twisted boundary conditions on a cubic volume (L) gives access to components of hadronic momenta other than integer multiples of 2π/L. Partial twisting avoids the need for new gluon configurations for every choice of momentum, while, as r...
