Sea Contributions to Spin 1/2 Baryon Structure, Magnetic Moments, and Spin Distribution

We treat the baryon as a composite system made out of a \lq\lq core" of three quarks (as in the standard quark model) surrounded by a \lq\lq sea" (of gluons and $q\bar{q}$-pairs) which is specified by its total quantum numbers like flavor, spin and color. Specifically, we assume the sea to be a flavor octet with spin 0 or 1 but no color. The general wavefunction for spin 1/2 baryons with such a sea component is given. Application to the magnetic moments is considered. Numerical analysis shows that a scalar (spin 0) sea with an admixture of a vector (spin 1) sea can provide very good fits to the magnetic moment data {\em using experimental errors}. Our best fit automatically gives $g_A/g_V$ for neutron beta decay in agreement with data. This fit also gives reasonable values for the spin distributions of the proton and neutron.Comment: 24 pages, REVTEX. References modifie

A priori mixed hadrons, hyperon non-leptonic decays, and the |\Delta I|=1/2 rule

The |\Delta I|=1/2 rule in non-leptonic decays of hyperons can be naturally understood by postulating a priori mixed physical hadrons, along with the isospin invariance of the responsible transition operator. It is shown that this operator can be identified with the strong interaction Yukawa hamiltonian.Comment: Workshops on Particles and Fields and Phenomenology of Fundamental Interactions. J. C.

CONFRONTING THE WILDFIRE CRISIS: UNDERSTANDING EQUITY AND DECISION-MAKING IN WILDFIRE MANAGEMENT STRATEGIES

This study investigates how fuel managers incorporate equity and social vulnerability considerations into wildfire fuel reduction treatments on National Forest land and explores the resulting impact on the implementation of wildfire risk reduction policies. Through interviews, managers revealed differing perspectives on prioritizing social vulnerability characteristics and challenges such as insufficient information and resources to inform equitable fuel treatment decisions. These findings illuminate the complexities of integrating considerations of social vulnerability into decision-making processes for wildfire management at the wildland-urban interface, suggesting potential divergence from nationally supported policies aimed at equitably implementing wildfire risk reduction measures. The study findings underscore the importance of addressing challenges associated with access to information and building capacity to enhance the equity and effectiveness of manager’s fuel reduction decision-making
