Analysis of the b 1 meson decay in local tensor bilinear representation

open access: yesJournal of High Energy Physics, 2018
We explore the validity of vector meson dominance in the radiative decay of the b 1(1235) meson. In order to explain the violation of the vector meson dominance hypothesis in this decay process, we investigate a model where the b 1 meson strongly couples

Low-energy effective action for pions and a dilatonic meson [PDF]

open access: yes, 2016
Numerical simulations of QCD-like theories in which the number of flavors is adjusted so that the beta function is very small, but confinement and chiral symmetry breaking nevertheless take place, appear to reveal the presence of a flavor-singlet scalar ...

Parity nonconservation effects in the photodesintegration of polarized deuterons [PDF]

open access: yes, 2002
P-odd correlations in the deuteron photodesintegration are considered. The $\pi$-meson exchange is not operative in the case of unpolarized deuterons. For polarized deuterons a P-odd correlation due to the $\pi$-meson exchange is about $3 \times 10^{-9}$.

Lepton flavor non-universality in B-meson decays from a U(2) flavor model [PDF]

open access: yesJournal of High Energy Physics, 2015
We address the recent anomalies in semi-leptonic B-meson decays using a model of fermion masses based on the U(2) flavor symmetry. The new contributions to b → sℓℓ transitions arise due to a tree-level exchange of a Z′ vector boson gauging a U(1 ...

Towards the Assignment for the Ground Scalar Meson

open access: yesAdvances in High Energy Physics, 2013
Combining three complementary approaches, nonrelativistic constituent quark model, Regge phenomenology, and meson-meson mixing, we obtain the mass relations which relate different meson multiplets. With the help of known meson masses, these relations can

Charm meson scattering cross sections by pion and rho meson [PDF]

open access: yes, 2001
Using the local flavor SU(4) gauge invariance in the limit of vanishing vector meson masses, we extend our previous study of charm meson scattering cross sections by pion and rho meson, which is based only on the pseudoscalar-pseudoscalar-vector meson ...

Dilepton Spectra from Decays of Light Unflavored Mesons [PDF]

open access: yes, 1999
The invariant mass spectrum of the $e^{+}e^{-}$ and $\mu ^{+}\mu ^{-}$ pairs from decays of light unflavored mesons with masses below the $\phi (1020)$-meson mass to final states containing along with a dilepton pair one photon, one meson, and two mesons
