DOI: 10.1007/jhep08(2018)179
Abstract: A bstractWe explore the validity of vector meson dominance in the radiative decay of the b1(1235) meson. In order to explain the violation of the vector meson dominance hypothesis in this decay process, we investigate… read more here.

DOI: 10.1007/s11182-019-01683-2
Abstract: This work investigates the interaction of an axial vector-meson with nucleons in the AdS/QCD soft wall model. The axial vector fields have been determined inside the anti-de Sitter (AdS) space with the help of gauge… read more here.

DOI: 10.1016/j.nuclphysb.2019.114718
Abstract: Abstract We study the two-body charmed nonleptonic weak decays of the bottom meson to an axial-vector meson and a pseudoscalar meson using the non-relativistic quark model. We employ the factorization hypothesis to obtain the branching… read more here.

DOI: 10.1103/physrevd.100.116009
Abstract: In this work we study contributions due to vector and axial-vector meson fluctuations to their in-medium spectral functions in an effective low-energy theory inspired by the gauged linear sigma model. In particular, we show how… read more here.

DOI: 10.1103/physrevd.105.035036
Abstract: Electron beam fixed target experiments such as NA64 and LDMX use missing energy-momentum to detect the production of dark matter and other long-lived states. The most studied production mechanism is dark Bremsstrahlung through a vector… read more here.

DOI: 10.1103/physrevd.111.013004
Abstract: An extended vector meson dominance model is developed to describe electromagnetic nucleon form factors. The model includes families of the ρ- and ω-mesons with the associated radial excitations. The free parameters of the model are… read more here.

DOI: 10.1134/s1063778824700315
Abstract: Advantages of the amplitude method for the vector-meson-production description in respect of the spin-density-matrix-element (SDME) method are discussed. It is shown that for any nonzero amplitudes the angular distribution of final particles is non-negative. The… read more here.
