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 ...

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.

Quantum Support Vector Machines for Continuum Suppression in B Meson Decays [PDF]
Computing and Software for Big Science, 2021 Quantum computers have the potential to speed up certain computational tasks. A possibility this opens up within the field of machine learning is the use of quantum techniques that may be inefficient to simulate classically but could provide superior ...

Relativistic corrections to the vector meson light front wave function [PDF]
Physical Review D, 2020 We compute a light front wave function for heavy vector mesons based on long distance matrix elements constrained by decay width analyses in the Non Relativistic QCD framework.
