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 ...

Inclusive B-decay spectra and IR renormalons. [PDF]
, 2010 I illustrate the role of infrared renormalons in computing inclusive B-decay spectra. I explain the relation between the leading ambiguity in the definition of Sudakov form factor exp(N /M) and that of the pole mass, and show how these ambiguities ...

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.

Vector meson dominance and the ρ meson [PDF]
Physical Review D, 1999 We discuss the properties of vector mesons, in particular the rho^0, in the context of the Hidden Local Symmetry (HLS) model. This provides a unified framework to study several aspects of the low energy QCD sector. Firstly, we show that in the HLS model the physical photon is massless, without requiring off field diagonalization.

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.

Physics Letters B, 2021 A novel observable measuring the CP asymmetry in multi-body decays of heavy mesons, which is called the forward-backward asymmetry induced CP asymmetry (FBI-CPA), ACPFB, is introduced. This observable has the dual advantages that 1) it can isolate the CP
