Cross sections for 2-to-1 meson–meson scattering

European Physical Journal C: Particles and Fields, 2021
We study the processes $$K{\bar{K}} \rightarrow \phi $$ K K ¯ → ϕ , $$\pi D \rightarrow D^*$$ π D → D ∗ , $$\pi {\bar{D}} \rightarrow {\bar{D}}^*$$ π D ¯ → D ¯ ∗ , and the production of $$\psi (3770)$$ ψ ( 3770 ) , $$\psi (4040)$$ ψ ( 4040 ) , $$\psi ...

$\eta \to \pi^0 \gamma \gamma$ decay within unitarized chiral perturbation theory [PDF]

, 2002
We improve the calculations of the $\eta \to \pi^0 \gamma \gamma$ decay within the context of meson chiral lagrangians. We use a chiral unitary approach for the meson-meson interaction, thus generating the $a_0(980)$ resonance and fixing the longstanding

Inelastic meson-meson scattering in hadronic matter [PDF]

Modern Physics Letters A, 2020
We review studies of inelastic meson-meson scattering. In nonperturbative schemes with chiral-perturbation-theory Lagrangians and in models based on effective meson Lagrangians, inelastic meson-meson scattering leads to the successful identification of resonances in meson-meson reactions, adequate inclusion of final state interactions in particle ...

The role of meson exchanges in light-by-light scattering

Physics Letters B, 2017
We discuss the role of meson exchange mechanisms in γγ→γγ scattering. Several pseudoscalar (π0, η, η′(958), ηc(1S), ηc(2S)), scalar (f0(500), f0(980), a0(980), f0(1370), χc0(1P)) and tensor (f2(1270), a2(1320), f2′(1525), f2(1565), a2(1700)) mesons are ...

ηc-nucleus bound states

Physics Letters B, 2020
ηc-nucleus bound state energies are calculated for various nuclei. Essential input for the calculations, namely the medium-modified D and D⁎ meson masses, as well as the density distributions in nuclei, are calculated within the quark-meson coupling (QMC)

Stark effect and dissociation of mesons in holographic conductor

Journal of High Energy Physics, 2023
We study the meson spectrum of the N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory with N $$ \mathcal{N} $$ = 2 fundamental hypermultiplets for a finite electric field by using the D3/D7 model.

Dilepton Spectra from Decays of Light Unflavored Mesons [PDF]

, 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
