NONLEPTONIC DECAYS OF CHARMED MESONS INTO TWO PSEUDOSCALAR MESONS [PDF]

open access: yesModern Physics Letters A, 1993
We investigate the nonleptonic decay of charmed meson into two pseudoscalar mesons using the vector-dominance model, and compare the results with those obtained from the factorization model. In particular, we discuss the role of the annihilation diagrams in the two models.

The light invisible boson in FCNC decays of B and $$B_c$$ B c mesons

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
In this paper, we study the FCNC decay processes of B and $$B_c$$ B c meson, in which one invisible particle is emitted. Both the spin-0 and spin-1 cases are considered.

The flavour singlet mesons in QCD [PDF]

open access: yes, 2001
We study the flavour singlet mesons from first principles using lattice QCD. We explore the splitting between flavour singlet and non-singlet for vector and axial mesons as well as the more commonly studied cases of the scalar and pseudoscalar mesons ...

DCC dynamics with the SU(3) linear sigma model [PDF]

open access: yes, 1998
The SU(3) extension of the linear sigma model is employed to elucidate the effect of including strangeness on the formation of disoriented chiral condensates.

Measurement of branching fractions for D meson decaying into ϕ meson and a pseudoscalar meson

open access: yesPhysics Letters B, 2019
The four decay modes D0→ϕπ0, D0→ϕη, D+→ϕπ+, and D+→ϕK+ are studied by using a data sample taken at the centre-of-mass energy s=3.773 GeV with the BESIII detector, corresponding to an integrated luminosity of 2.93 fb−1.

An Analysis of the Decay $B \rightarrow D^* X \ell \bar\nu_\ell$ with Predictions from Heavy Quark and Chiral Symmetry

open access: yes, 1992
This paper considers the implications of the heavy quark and chiral symmetries for the semi-leptonic decay $B \rightarrow D^* X \ell \bar \nu_\ell$. The general kinematic analysis for decays of the form {\sl pseudoscalar meson $\rightarrow$ vector meson $

The hyperon-nucleon interaction: conventional versus effective field theory approach [PDF]

open access: yes, 2007
Hyperon-nucleon interactions are presented that are derived either in the conventional meson-exchange picture or within leading order chiral effective field theory. The chiral potential consists of one-pseudoscalar-meson exchanges and non-derivative four-

Meson–baryon coupling constants of the SU(3) baryons with flavor SU(3) symmetry breaking

open access: yesPhysics Letters B, 2018
We investigate the strong coupling constants for the baryon octet–octet, decuplet–octet, and decuplet–decuplet vertices with pseudoscalar mesons within a general framework of the chiral quark-soliton model, taking into account the effects of flavor SU(3)
