Vector-meson production and vector meson dominance [PDF]
European Physical Journal C: Particles and Fields, 2021 We consider the fidelity of the vector meson dominance (VMD) assumption as an instrument for relating the electromagnetic vector-meson production reaction $$e + p \rightarrow e^\prime + V + p$$ e + p → e ′ + V + p to the purely hadronic process $$V + p ...

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 ...

Meson–nucleus potentials and the search for meson–nucleus bound states [PDF]
Progress in Particle and Nuclear Physics, 2017 Recent experiments studying the meson-nucleus interaction to extract meson-nucleus potentials are reviewed. The real part of the potentials quantifies whether the interaction is attractive or repulsive while the imaginary part describes the meson ...

Concavity of the meson Regge trajectories
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2018 It is illustrated by the fitted Regge trajectories for a large majority of mesons that the radial and orbital Regge trajectories for mesons prefer being concave in the (nr,M2) and (l,M2) planes, respectively. The concavity of the meson Regge trajectories

The role of meson exchanges in light-by-light scattering
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 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 ...

Analytical determination of Yukawa Potential: An iterative semiclassical approach [PDF]
Revista Brasileira de Ensino de Física, 2020 In this work we propose an alternative semiclassical iterative approach to obtain the Yukawa Potential, where the temporal evolution is replaced by the number of iterations.

Investigation of the meson-meson interaction
Physical Review C, 2022 In the framework of the quark delocalization color screening model, we investigate the meson-meson interaction in the fully light four-quark system . The calculation of the effective potentials of all the $S-$wave states shows that for most states the interaction between two vector mesons is attractive; the one between a pseudoscalar meson and a vector

Heavy-quark mesons in the diabatic approach: string breaking and the quarkoniumlike spectrum [PDF]
EPJ Web of Conferences, 2022 The Born-Oppenheimer approximation provides a description of heavy-quark mesons firmly based on lattice QCD, but its validity is limited to the lightest states lying far below the first open-flavour meson-meson threshold.

B - and D -meson leptonic decay constants from four-flavor lattice QCD [PDF]
Physical Review D, 2017 We calculate the leptonic decay constants of heavy-light pseudoscalar mesons with charm and bottom quarks in lattice quantum chromodynamics on four-flavor QCD gauge-field configurations with dynamical $u$, $d$, $s$, and $c$ quarks. We analyze over twenty
