Measurement of polarization transfer in the quasi-elastic 40Ca(e⃗,e′p⃗)^{40}{\rm Ca}(\vec{e},e' \vec{p}) process

Polarization transfer to a bound proton in polarized electron knock-out reactions, $\mathrm{A}(\vec{e},e^{\prime}\vec{p})$, is a powerful tool to look for in-medium modification of the bound proton. It requires comparison to calculations which consider the many-body effects accompanying the quasi-free process. We report here measured components $P_x^{\prime}$, $P_z^{\prime}$, and their ratio $P_x^{\prime}/P_z^{\prime}$, of polarization transfer to protons bound in $^{40}\mathrm{Ca}$, which is described well by the shell model and for which reliable calculations are available. While the calculations capture the essence of the data, our statistical precision allows us to observe deviations which cannot be explained by simple scaling, including by varying the proton electromagnetic form factor ratio $G_E/G_M$. We further explore the deviations of the ratio of the polarization transfer components from that of a free proton, $(P_x^{\prime}/P_z^{\prime})_{\rm A}/(P_x^{\prime}/P_z^{\prime})_{\rm H}$, and its dependence on the bound-proton virtuality

Measurement of polarization transfer in the quasi-elastic Ca40(e→,e′p→) process

Polarization transfer to a bound proton in polarized electron knock-out reactions, A(e→,e′p→), is a powerful tool to look for an in-medium modification of the bound proton. It requires comparison to calculations that consider the many-body effects accompanying the quasi-free process. We report here measured components Px′, Pz′, and their ratio Px′/Pz′, of polarization transfer to protons bound in Ca40, which is described well by the shell model and for which reliable calculations are available. While the calculations capture the essence of the data, our statistical precision allows us to observe deviations that cannot be explained by simple scaling, including by varying the proton electromagnetic form factor ratio GE/GM. We further explore the deviations of the ratio of the polarization transfer components from that of a free proton, (Px′/Pz′)A/(Px′/Pz′)H, and its dependence on the bound-proton virtuality

Diversification and internationalization in the sociological study of science and religion

Classical sociology addressed the relationship between science and religion, but interest in the topic waned during the 20th century. A second wave of research has emerged in the 21st century, focusing on scientists' (ir)religiosity, evolution, and the relationship between knowledge and acceptance of scientific concepts. Most of this research has been conducted in the United States, used quantitative methods, and focused on creationism, although scholars have recently begun to explore different research methods and sites. Their results suggest that the “conflict thesis” is not valid and that publics and scientists' views tend to be fluid and strongly shaped by national context. The literature on nonreligion has also expanded, but its connection to science remains ripe for further development. A more intersectional approach would also benefit the field, as would increased engagement between public understanding of science scholars and sociologists studying science and religion. Research in both areas is showing that attitudes toward science and religion cannot be understood solely in terms of knowledge about either domain. There is scope for more empirical and theoretical work internationally eschewing the assumption that science and religion conflict and focusing more on identity, culture, and power relations
