Vector meson dominance and polarization

open access: yesNuclear Physics B, 1968
Abstract The vector dominance model relates amplitudes for reactions induced by photons (e.g., ifπ-production from nucleons) to amplitudes for reactions induced by vector mesons. In the applications of such relations one conventionally assumes that the vector mesons have to be polarized transversely with respect to the c.m. system.

EXCLUSIVE VECTOR MESON ELECTROPRODUCTION @ CLAS [PDF]

open access: yesExclusive Reactions at High Momentum Transfer IV, 2011
We present the results of exclusive electroproduction of vector mesons on the proton at CLAS. We discuss the interpretation of these cross sections in terms of t-channel Reggeon exchanges and in terms of Generalized Parton Distributions (GPDs) formalism.

Phenological Variation and Evolution Across Space and Time in the Scarlet Monkeyflower (Erythranthe cardinalis)

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Climate change is altering ecological dynamics, particularly in species with latitudinal range variation. This study investigates how the scarlet monkeyflower's flowering phenology has evolved in response to recent droughts in California. We find that southern populations are flowering later and larger, while northern populations flower earlier and ...

VECTOR MESON PRODUCTION AT HERA [PDF]

open access: yesInternational Journal of Modern Physics A, 2009
The rich experimental landscape of exclusive vector meson production at the high energy electron–proton collider HERA is reviewed, with emphasis on the transition from soft to hard diffraction and QCD interpretations.

Legacy effects of inundation on greenhouse gas emissions and soil dynamics in forage systems

open access: yesAgronomy Journal, Volume 117, Issue 6, November/December 2025.
Abstract Soil inundation increases anaerobiosis, slows organic matter decomposition, and affects greenhouse gas production from soils. The objective of this study was to evaluate the effects of natural short‐duration recurring inundation on CO2, CH4, and N2O emissions, as well as on labile soil permanganate oxidizable carbon and autoclaved‐citrate ...

X(3872): propagating in a dense medium

open access: yesNuclear Physics B, 2018
In cold nuclear matter, the shifts in the mass and current-meson coupling as well the vector self energy of the exotic X(3872) are calculated using the diquark–antidiquark current within the framework of the in-medium two-point QCD sum rule.

Linking herbicide cross‐tolerance to agronomic and seed vigor traits: A multi‐trait genome‐wide association study in snap bean (Phaseolus vulgaris L.)

open access: yesCrop Science, Volume 65, Issue 6, November/December 2025.
Abstract In snap bean (Phaseolus vulgaris L.) production, herbicides are essential for weed control, requiring crop tolerance to avoid injury. The study aimed to link genomic loci to agronomic traits, explore the extent of herbicide cross‐tolerance, and identify loci influencing seed vigor and herbicide tolerance traits. A panel was evaluated for seven

Impact of vector meson polarization on its interaction with matter

open access: yesEuropean Physical Journal C: Particles and Fields
The production of unstable particles on different nuclei provides the possibility to determine the total cross section of the interaction of vector mesons $$V=\rho ,\omega ,\varphi , K^{*0}(892),J/\psi $$ V = ρ , ω , φ , K ∗ 0 ( 892 ) , J / ψ etc.

Light Vector Meson Spectroscopy [PDF]

open access: yes, 2001
The current situation for vector meson spectroscopy is outlined, and it is shown that the data are inconsistent with the generally-accepted model for meson decay. A possible resolution in terms of exotic (hybrid) mesons is given. Although this hypothesis
