Vector-meson production and vector meson dominance [PDF]
European Physical Journal C: Particles and Fields, 2021 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 ...

Complete calculation of exclusive heavy vector meson production at next-to-leading order in the dipole picture [PDF]
Journal of High Energy Physics, 2022 Exclusive production of transversely polarized heavy vector mesons in deep inelastic scattering at high energy is calculated at next-to-leading order accuracy in the Color Glass Condensate framework.

Analysis of the b 1 meson decay in local tensor bilinear representation [PDF]
Journal of High Energy Physics, 2018 We explore the validity of vector meson dominance in the radiative decay of the b 1(1235) meson. In order to explain the violation of the vector meson dominance hypothesis in this decay process, we investigate a model where the b 1 meson strongly couples

Pseudoscalar meson and vector meson interactions and dynamically generated axial-vector mesons [PDF]
Physical Review D, 2014 The axial-vector mesons ${a}_{1}(1260)$, ${b}_{1}(1235)$, ${f}_{1}(1285)$, ${h}_{1}(1170)$, ${h}_{1}(1380)$, and ${K}_{1}(1270)$ are dynamically generated in the unitized chiral perturbation theory.

Zero temperature properties of mesons in a vector meson extended linear sigma model [PDF]
EPJ Web of Conferences, 2011 A three flavor linear sigma model with vector and axial-vector mesons is discussed. Preliminary results concerning on the symmetry breaking pattern, the question of parameterization, as well as the resulting meson masses are presented.

Vector meson spin alignment by the strong force field [PDF]
Nuclear Science and Techniques, 2023 Observation of unexpectedly large global spin alignment of $\phi$ vector mesons in non-central heavy-ion collisions by STAR experiment may reveal the non-perturbative nature of quark interaction in hot matter through fluctuating strong force field with ...

Vector mesons on the wall [PDF]
Journal of High Energy Physics, 2021 AbstractA domain-wall configuration of theη′meson bounded by a string (called a pancake or a Hall droplet) is recently proposed to describe the baryons with spinNc/2. In order to understand its baryon number as well as the flavor quantum number, we argue that the vector mesons (theρandωmesons) should play an essential role for the consistency of the ...

Probing invisible vector meson decays with the NA64 and LDMX experiments [PDF]
Physical Review D, 2021 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 mediator.

Extraction of the proton mass radius from the vector meson photoproductions near thresholds [PDF]
, 2021 We present an analysis of the proton mass radius by studying the t-dependence of the differential cross sections of the vector meson photoproductions near the thresholds.
