STKE: A Proton Gradient Signals Asymmetry

Asymmetry dependence of proton correlations.

A dispersive-optical-model analysis of p+40Ca and p+48Ca interactions has been carried out. The real and imaginary potentials have been constrained from fits to elastic-scattering data, reaction cross sections, and level properties of valence hole states deduced from (e, e' p) data. The surface imaginary potential was found to be larger overall and the gap in this potential on either side of th...

Double-spin asymmetry in elastic proton-proton scattering as a probe for the Odderon

The magnitude of the double-spin asymmetry ANN in polarized proton elastic scattering is estimated using results from an earlier determination of the spin-flip coupling of the leading Regge poles [1]. The required Regge cuts are estimated using the absorptive Regge model. This estimate is then used to determine the sensitivity of experiments at RHIC to the presence of the Odderon. This manuscri...

Measurement of the Electrochemical Proton Gradient in

The pH gradient and membrane potential of submitochondrial particles from bovine heart were estimated by the uptake of ["C]ethylamine and ["'Cl]perchlorate, using filtration through a glass fiber prefilter and Millipore filter without washing to separate the vesicles from the medium. An external volume probe of ['HI sucrose was also used. Internal volume of the vesicles was measured by the exte...

Baryon Asymmetry of the Proton Sea at Low x

We predict a nonvanishing baryon asymmetry of the proton sea at low x. It is expected to be about 7% and nearly x-independent at x < 0.5×10−3. The asymmetry arises from the baryon-antibaryon component of the Pomeron, rather than from the valence quarks of the proton, which are wide believed carriers of baryon number. Experimental study of x-distribution of the baryon asymmetry of the proton sea...
