It is shown how Maxwell’s equations for the electromagnetic field with Planck quantisation of allowed modes appears to provide a semiclassical account of nuclear interactions. The mesons emerge as plasmons, collective excitations in an electron positron

Excitation Spectrum in the Friedberg-Lee Model [PDF]
The excitation spectrum of the nucleon with the spin 1/2 is examined by using the Friedberg-Lee model containing the constituent quark and the scalar meson. An appropriate way of quantization for the non-linear meson field is employed by taking account

We report results on a feasibility study of measuring the properties of φ (1020) resonance in collisions of bismuth nuclei at an energy of 9.2 GeV using the MPD detector at the NICA collider.

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
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.

Vector-meson production and vector meson dominance
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 ...

Free energies as invariants of Teichmüller like structures [PDF]
A Teichmüller like structure on the space of d-degree holomorphic maps on the circle S1, marked by conjugations to the map z 7→ z d, can be defined. Here we introduce a definition of free energy associated to this kind of dynamics as an invariant of ...

Chiral effective lagrangians may differ in their prediction of meson-nucleon scattering amplitudes off-meson-mass-shell, but must yield identical S-matrix elements.

We present a systematic study of the valon distribution functions and valon structure functions for pions and kaons. The implications of our results for low-${p}_{T}$ inclusive reactions are emphasized. The complications with the structure function of strange valons are discussed and suggestions are made for future experiments to extract it from the ...

Meson Masses and Energetics of Meson Decay [PDF]
A series of measurements of the π- and μ-meson masses and their decay energies is reviewed. Recent mass measurements made at the University of California Radiation Laboratory have employed an improved method in which the ratio of the π-meson mass to that of the proton and the ratio of the μ-meson mass to that of the π-meson were determined by measuring
