Weak capture of protons by protons
The cross section for the proton weak capture reaction H(p,eνe) H is calculated with wave functions obtained from a number of modern, realistic high-precision interactions. To minimize the uncertainty in the axial two-body current operator, its matrix element has been adjusted to reproduce the measured Gamow-Teller matrix element of tritium β decay in model calculations using trinucleon wave fu...
متن کاملTheory of Scattering of Protons by Protons
quantitatively in agreement, as regards 'magnitudes, variation with angle, and variation with voltage, with a simple phase shift of the spherically symmetrical de Broglie wave ("S wave") due to the collision or scattering, corresponding to a new attractive force overpowering the Coulomb repulsion, and give a rather accurate measure of the "potential well" which is therefore permissible as repre...
متن کاملPolarized Protons in HERA
Polarized proton beams at HERA can currently only be produced by extracting a beam from a polarized source and then accelerating it in the three synchrotrons at DESY. In this paper, the processes which can depolarize a proton beam in circular accelerators are explained, devices which could avoid this depolarization in the DESY accelerator chain are described, and specific problems which become ...
متن کاملKK̄ photoproduction from protons
We study the contribution of the Drell mechanism driven by K + and K − exchange to the reaction γN →K ¯ KN. Our calculation implements the full KN and ¯ KN reaction amplitudes in the form of partial wave amplitudes taken from a meson-exchange model (KN) and a partial wave analysis (¯ KN), respectively. Comparing our results to data of the LAMP2 collaboration we observe that the Drell mechanism ...
متن کاملProtons Trigger Mitochondrial Flashes.
Emerging evidence indicates that mitochondrial flashes (mitoflashes) are highly conserved elemental mitochondrial signaling events. However, which signal controls their ignition and how they are integrated with other mitochondrial signals and functions remain elusive. In this study, we aimed to further delineate the signal components of the mitoflash and determine the mitoflash trigger mechanis...
