The light scalar mesons as tetraquarks
Physics Letters B, 2016 We present a numerical solution of the four-quark Bethe–Salpeter equation for ground-state scalar tetraquarks with JPC=0++. We find that the four-body equation dynamically generates pseudoscalar-meson poles in the Bethe–Salpeter amplitude.

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

Determining the dominant partial wave contributions from angular distributions of single- and double-polarization observables in pseudoscalar meson photoproduction [PDF]
, 2016 .This work presents a simple method to determine the significant partial wave contributions to experimentally determined observables in pseudoscalar meson photoproduction. First, fits to angular distributions are presented and the maximum orbital angular

Study of the Ground‐State Energies of Some Nuclei Using Hybrid Model
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 The quark‐quark (QQ) interaction as a perturbed term to the nucleon‐nucleon interaction (NN) without any coupling between them is studied in a hybrid model. This model is used to calculate the ground‐state energies of 2H1 and 4He2 nuclei. In a semirelativistic framework, this model is encouraged for light nuclei and the instanton‐induced interaction by

Trace and Axial Anomalies on Equal Footing
Advances in High Energy Physics, 2020 We discussed that for some particular nonsupersymmetric theories, a generalized symmetry that includes both the scale and axial transformations and leads to a single current may contain also a pseudoscalar term. The method, inspired by the superconformal

Effects of nonequilibrated topological charge distributions on pseudoscalar meson masses and decay constants [PDF]
, 2017 We study the effects of failure to equilibrate the squared topological charge $Q^2$ on lattice calculations of pseudoscalar masses and decay constants. The analysis is based on chiral perturbation theory calculations of the dependence of these quantities

European Physical Journal C: Particles and Fields, 2018 We investigate the decays of $$\bar{B}^0_s$$ B¯s0 , $$\bar{B}^0$$ B¯0 and $$B^-$$ B- into $$\eta _c$$ ηc plus a scalar or vector meson in a theoretical framework by taking into account the dominant process for the weak decay of $$\bar{B}$$ B¯ meson into $

Deeply Virtual Pseudoscalar Meson Production at Jefferson Lab and Transversity GPDs [PDF]
, 2016 The cross section of the exclusive $\pi^0$ and $\eta$ electroproduction reaction $ep\to e^\prime p^\prime \pi^0/\eta$ was measured at Jefferson Lab with a 5.75-GeV electron beam and the CLAS detector.
