Concavity of the meson Regge trajectories
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
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]
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.

Heavy-quark mesons in the diabatic approach: string breaking and the quarkoniumlike spectrum [PDF]
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.

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

The Ds0(2590)+ as the dressed cs¯(21S0) meson in a coupled-channels calculation
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.

A tres rondas del final: Un acercamiento teórico postfreudiano al goce sin angustia del síntoma (psicopatía) del trauma moderno (colapso) [PDF]
Este trabajo se centra en la casuística del colapso civilizatorio occidental y la estructura caracteriológica que lo sostiene y lo va a sufrir. Dedicaré todo un apartado a exponer datos de organismos oficiales y personalidades contrastadas del mundo ...

On the topological entropy of the irregular part of v-statistics multifractal spectra [PDF]
Let (x, d) be a compact metric space and f : x → x, if xr is the product of r−copies of x, r ≥ 1, and φ : xr → r, then the multifractal decomposition for v −statistics is given by eφ (α) = ( x : lim n→∞ 1 nr p 0≤i1≤...≤ir≤n−1 φ ¡ f i1 (x) , ..., fir (x) ¢

Strong Effective Coupling, Meson Ground States, and Glueball within Analytic Confinement
The phenomena of strong running coupling and hadron mass generating have been studied in the framework of a QCD-inspired relativistic model of quark-gluon interaction with infrared-confined propagators.
