Extremal Polynomial Norms of Graphs

Ángel Chávez, Sarah Fullerton, Matilda LaFortune, Keyron Linarez et autres

Recent work shows that a new family of norms on Hermitian matrices arise by evaluating the even degree complete homogeneous symmetric (CHS) polynomials on the eigenvalues of a Hermitian matrix. The CHS norm of a graph is then defined by evaluating the …

Precision Measurement of the p(e,e′p)π[superscript 0] Reaction at Threshold

K. Chirapatpimol, M. Shabestari, R. A. Lindgren, L. C. Smith et autres

New results are reported from a measurement of π[superscript 0] electroproduction near threshold using the p(e,e[superscript ′]p)π[superscript 0] reaction. The experiment was designed to determine precisely the energy dependence of s- and p-wave electromagnetic multipoles as a stringent test of the predictions …

G E p / G M p Ratio by Polarization Transfer in e → p → e p →

M. Jones, K. Aniol, F. T. Baker, J. Berthot et autres

The ratio of the proton's elastic electromagnetic form factors, ${G}_{{E}_{p}}{/G}_{{M}_{p}}$, was obtained by measuring ${P}_{t}$ and ${P}_{\ensuremath{\ell}}$, the transverse and the longitudinal recoil proton polarization, respectively. For elastic $\stackrel{\ensuremath{\rightarrow}}{e}p\ensuremath{\rightarrow}e\stackrel{\ensuremath{\rightarrow}}{p}$, ${G}_{{E}_{p}}{/G}_{{M}_{p}}$ is proportional to ${P}_{t}{/P}_{\ensuremath{\ell}}$. Simultaneous measurement of ${P}_{t}$ and ${P}_{\ensuremath{\ell}}$ in a …
