The coupling constant of a vector meson with delta baryons in the AdS/QCD model is investigated. A pseudoscalar field is introduced inside the anti-de Sitter (AdS) space to break the chiral symmetry together with gauge fields with left and right chir

We have investigated the effect of nucleon and delta resonances with spins $11/2$, $13/2$, and $15/2$ in the kaon photoproduction process $\ensuremath{\gamma}+N\ensuremath{\rightarrow}K+Y$ by using two covariant isobar models. The formalism for high-

The vector $U$ bosons, or so-called ``dark photons,'' are one of the possible candidates for the dark matter mediators. They are supposed to interact with the standard matter via a ``vector portal'' due to the $U(1)\ensuremath{-}U(1{)}^{\ensuremath{'

Quantizing a soliton on a hypersphere, we obtain the first class Hamiltonian, and evaluate the baryon physical quantities which are in good agreement with the corresponding experimental data. In particular, we find that the predicted value for axial

A future gamma factory at CERN or accelerator-based gamma sources elsewhere can include the possibility of energetic twisted photons, which are photons with a structured wave front that can allow a pre-defined large angular momentum along the beam di

In this work, we study magnetic field effects on neutron star matter containing the baryon octet and additional heavier spin 3/2 baryons (the $\Delta$'s). We make use of two different relativistic hadronic models that contain an additional vector-iso

The photoproduction of γp→K+Σ0(1385) is investigated based on an effective Lagrangian approach using the tree-level Born approximation, with the purpose of understanding the reaction mechanisms and resonance contents and their associated paramete

We investigate the hadron-quark phase transition in cold neutron stars in light of (i) the observed limits on the maximum-mass of heavy pulsars, (ii) constraints on the tidal properties inferred from the gravitational waves emitted in binary neutron-

International audience; The presence of exotic hadrons, such as hyperons and Δ isobars, in the dense nuclear matter in their cores has been shown to produce important changes in the properties of neutron stars. Within the quark-meson coupling model,
