Probing moments of baryon-antibaryon generalized parton distributions at BELLE and FAIR

We analyze the time-like processes gamma gamma -> B Bbar and p p-bar -> gamma M at large Mandelstam variables within the handbag approach for which the process amplitudes factorize in hard partonic subprocesses and annihilation form factor. The latter represent moments of baryon-antibaryon generalized parton distributions. Symmetry relations restrict the number of independent annihilation form factors for the ground state baryons drastically. We determine these form factors from the present BELLE data on gamma gamma -> B Bbar with the help of simplifying assumptions. The knowledge of these form factors allow for predictions of p pbar -> gamma M for various mesons which may be probed at FAIR.Comment: 17 pages, 7 figure

QCD at high baryon density in a random matrix model

A high density diquark phase seems to be a generic feature of QCD. If so it should also be reproduced by random matrix models. We discuss a specific one in which the random matrix elements of the Dirac operator are supplemented by a finite chemical potential and by non-random elements which model the formation of instanton-anti-instanton molecules. Comparing our results to those found in a previous investigation by Vanderheyden and Jackson we find additional support for our starting assumption, namely that the existence of a high density diquark phase is common to all QCD-like models.Comment: 16 pages, 4 figures, final version to appear in Eur.Phys.J.

The Skyrme Model piNN Form Factor and the Sea Quark Distribution of the Nucleon

We calculate the sea quark distribution of the nucleon in a meson cloud model. The novel feature of our calculation is the implementation of a special piNN form factor recently obtained by Holzwarth and Machleidt. This form factor is hard for small and soft for large momentum transfers. We show that this feature leads to a substantial improvement.Comment: 9 pages, 5 figures; v2: some typos corrected, including eq. (9

Three in Ten Rural and Urban Medicaid Recipients May Be Affected by Potential Work Requirements

In this fact sheet, authors Andrew Schaefer and Jessica Carson explore whether rural and urban Medicaid recipients would be differentially affected by a work requirement. They focus on Medicaid recipients through a rural/urban lens because rural adults differ from their urban counterparts on a host of demographic characteristics. They report that about three in ten Medicaid recipients could be affected by a work requirement, a share that is similar in rural and urban places. Among Medicaid recipients potentially affected by a work requirement, the majority worked at least part of the previous year or were motivated to work but could not find a job, a share that is slightly higher in rural places than in urban. The especially high share of those already working or looking for work in rural places may warrant additional consideration from legislators representing rural areas. In both rural and urban places, legislators should consider whether the consequences to families losing health insurance coverage outweigh the relative benefits of enforcing work requirements

Simple circuit performs binary addition and subtraction

Ripple adder reduces the number of logic circuits required to preform binary addition and subtraction. The adder uses dual input and delayed output flip-flops in one register. The contents of this register are summed with those of a standard register through conventional AND/gates
