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 ...

Particles, 2019 We give a pedagogical review of the properties of the various meson condensation phases triggered by a large isospin or strangeness imbalance. We argue that these phases are extremely interesting and powerful playground for exploring the properties of hadronic matter. The reason is that they are realized in a regime in which various theoretical methods

The Ds0(2590)+ as the dressed cs¯(21S0) meson in a coupled-channels calculation
Physics Letters B, 2022 The recent discovery of the Ds0(2590)+ meson by the LHCb Collaboration has stimulated the analysis of meson-meson channels effects in the two-body quark-antiquark meson spectrum.

Three channel model of meson-meson scattering and scalar meson spectroscopy [PDF]
Physics Letters B, 1997 New solutions on the scalar -- isoscalar $ $ phase shifts are analysed together with previous $K\bar{K}$ results using a separable potential model of three coupled channels ($ $, $K\bar{K}$ and an effective $2 2 $ system). Model parameters are fitted to two sets of solutions obtained in a recent analysis of the CERN-Cracow-Munich measurements ...

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 ...

Decay constants and form factors of s-wave and p-wave mesons in the covariant light-front quark model [PDF]
, 2011 We reanalyze the decay constants of s-wave and p-wave mesons and D, B ->M form factors, where M represents a pseudoscalar meson, a vector meson, a scalar meson, or an axial vector meson within a covariant light-front quark model. The parameter \beta for wave-functions of most of s-wave mesons and of a few axial-vector mesons are fixed with latest ...

The non-perturbative unquenched quark model
EPJ Web of Conferences, 2017 In recent years states in the quarkonium spectrum not expected in the naive quark model have appeared and created a lot of interest. In the theoretical side the study of the effect of meson-meson thresholds in the spectrum have been performed in ...

Measurement of branching fractions for D meson decaying into ϕ meson and a pseudoscalar meson
Physics Letters B, 2019 The four decay modes $D^{0}\to ^{0}$, $D^{0}\to $, $D^{+}\to ^{+}$, and $D^{+}\to K^{+}$ are studied by using a data sample taken at the centre-of-mass energy $\sqrt{s} = 3.773$~GeV~with the BESIII detector, corresponding to an integrated luminosity of 2.93 fb$^{-1}$. The branching fractions of the first three decay modes are measured to be ${

(Anti-)Stokes scattering on kinks
Journal of High Energy Physics, 2023 At leading order, there are three inelastic scattering processes beginning with a quantum kink and a fundamental meson. Meson multiplication, in which the final state is a kink and two mesons, was treated recently.
